 Research & technology: not a cost (24 Feb 10)
Private companies must join the Government in increasing investment in research and technology if knowledge-based industries are to transform New Zealand's economy over the next decade, says the Prime Minister's chief science adviser.
Sir Peter Gluckman, speaking yesterday at a medical technology conference in Auckland, said private sector spending on research and technology was "dismally low".
"We're the only advanced country in which the Government spend [on research, science and technology] is actually higher than the private spend," he said.
Gluckman said the New Zealand Government spent 0.5 to 0.7 per cent of GDP on research and technology, while the private sector invested around 0.4 per cent "at best".
Conversely, he said, the private sectors of other advanced nations contributed as much as 2 per cent - out of a total spend of up to 3 per cent of GDP - on research and technology.
New Zealand had "paid the price" for failing to invest in knowledge-based sectors, he said. "For
many decades we've seen investment in research and science essentially as a cost
... rather than recognising it as a fundamental investment in the infrastructure
of our future."

 AgResearch
CEO resigns (4 Feb 10)
Today Dr Andrew West, Chief Executive of AgResearch Ltd, announced his intention to resign his position effective 30 June after six years in the role. AgResearch is the New Zealand Government’s principal research institute focused on this country’s dairy, red-meat and wool industries. AgResearch Chairman, Sam Robinson, has advised that the Board is not yet in a position to decide on the recruitment process for a new Chief Executive and will announce this in due course. Dr West has agreed to continue to lead AgResearch until mid 2010 to support the Board with the transition to a new Chief Executive.
“It has been fantastic to lead such an excellent and motivated group of staff for so long. It has been deeply fulfilling to bring an outstandingly competent institute closer to the industries that it was set up to serve. Likewise, I feel privileged to have worked with many others to assist in rebuilding recognition of the vital importance of New Zealand’s pastoral sector and more broadly the critical roles of science and technology,” said Dr West. “While it has been great to contribute in such ways, I believe that it has now got to the stage that AgResearch should continue to revitalise itself under new leadership. For me personally, I certainly intend to pursue opportunities in the science and technology space; these are areas where I believe that New Zealand is gaining real momentum”.
AgResearch Chairman, Sam Robinson, commended Dr West on his leadership of AgResearch. “Dr West focused AgResearch where New Zealand most needs it – on the pastoral sector and its associated food and textile products. The Board of Directors recognises his important contribution to the ongoing success of this company and wishes him well for his future beyond AgResearch”.
 $1b
sales boost possible for Zespri (9 Nov 09)
New Zealand kiwifruit sales could be boosted by between $300 million and $1 billion
a year within a decade thanks to a big investment venture announced by marketer Zespri and
the Government. Research Science and Technology Minister Wayne Mapp said $35.7
million would be invested over the next seven years in a joint research and development
programme by Zespri, the world's leading kiwifruit marketer, and the Crown Research
Institute Plant and Food Research. The Foundation for Research
Science and Technology would contribute $15.2 million and Zespri $20.5 million.
The funds are to accelerate and upscale New Zealand's kiwifruit breeding programme.
The boost will make it the world's biggest and most significant new kiwifruit
varieties R&D project. Zespri chief executive Lain Jager said a number of new
cultivars would be brought to market and it was "realistic" to expect that one
outstanding cultivar would be commercialised with forecast sales of $300 million
a year. Plant and Food Research chief operating officer Bruce Campbell told the
Business Herald his institute was planning for at least four "outstanding" cultivars
to be commercialised. "I think the numbers will be something like $1 billion
of sales by 2021." Kiwifruit is New Zealand's biggest horticulture export, accounting
for 45 per cent of all horticulture exports and 66 per cent of fresh fruit exports.
The industry's economic value is estimated at $1.45 billion a year. Zespri expects
the volume and value of the industry to at least double over the next 10 years.

 Ice
cream to battle chemo side effects (29 Oct 09)
Ice cream that could combat negative side effects of chemotherapy was today revealed
by diary giant Fonterra and Auckland University. The medicinal ice cream, known
as ReCharge, has started phase 2 clinical trials in New Zealand
to assess its effectives against chemotherapy induced diarrhoea (CID) and anaemia.
It could also reduce weight loss and damage to the immune system during chemo
treatement. Oncology centres throughout the country are taking part in the trial
and 10 patients are already signed up for a daily regime that includes eating
a 100gm tub of strawberry ice cream that contains two active dairy ingredients
that combine to address the side effects. LactoPharma, a partnership
between Fonterra and the university, screened dairy components for health effects.
Fonterra chief technology officer Dr Jeremy Hill said the two
bio-active milk components developed for the ice cream have the potential to
assist the body in coping with the side effects of chemotherapy. LactoPharma
is funded by Fonterra and the taxpayer through the Foundation for Research, Science
and Technology. They jointly invested $2 million to develop the ice cream. More

The inaugural NZ Institute of Food Science & Technology (NZIFST)
Student Product Development Challenge has been won by a team from Westlake
Girls High, with an Asian-style dumpling product called DelicAsia.
This is what the judges had to say about the product they developed: “This product
recognises the fusion of east:west cuisines and offers consumers flavours of
the west in a product form from the east. This team demonstrated great understanding
of their cultural differences to create a product that crosses cultures and meets
many needs.”
The team worked with the guidance of teacher Merryl Hamling, was mentored by
Futureintech Ambassador Fiona Greig from Beef + Lamb New Zealand, and sponsored
by Jerry Wellington FNZIFST. Products and
projects were judged by a by a team of senior food technologists and NZIFST Fellows,
Kay McMath, Dave Pooch, Gerard Hall and Marion Cumming. Final results and full

 Kiwifruit
good for liver, living longer (24 Oct 09)
A kiwifruit a day may be just as good at keeping the doctor away as an apple.
The furry fruit could be the key to living longer as it appears to be the perfect
food for preventing all sorts of liver problems, as well as keeping white blood
cells healthy, says Professor Robin Fraser, of Otago University's Christchurch
School of Medicine. Fraser, who has seen many unhealthy livers in his time as
a pathologist, is a convert to the benefits of the fruit. Fraser likened the
liver to a sieve that when working properly effectively filtered the carrier
of cholesterol. But those holes could be closed because of excess drinking, an
overly fatty diet, smoking, illicit drug use and stress, he said. That led to
atherosclerosis, which was a major killer through heart failure, strokes, gangrenous
feet and aortic aneurism. A daily dose of kiwifruit, along with a healthier lifestyle,
appeared to be able to reopen those holes in the liver, he said. Fraser, who
was speaking at the annual scientific meeting of the Royal College of Pathologists
of Australasia in Christchurch yesterday, said it was an exciting development.
He said kiwifruit was the most efficient way of getting the recommended dose
of vitamin C, the active ingredient that appeared to fix the liver. Dr Margreet
Vissers, the dean of research at Otago University in Christchurch, said that
while most people thought of oranges for vitamin C, kiwifruit was the better
option. "Out of one kiwifruit you will get the complete recommended daily allowance." More

 Potato
Genome Sequence released (23 Sep 09)
The Potato Genome Sequencing Consortium (PGSC), an international team of scientists including New Zealand’s
Plant & Food Research, has announced that it has released the first draft sequence of the potato genome. The PGSC started work on the project three years ago. The resulting 'blueprint' of how the potato works could revolutionise breeding programs.
Potato, a key member of the Solanaceae family, is a close relative of tomato, pepper and eggplant. It is the world's third most important crop and the most important vegetable crop. Access to the potato genome sequence, the “genetic blueprint” of how a potato plant grows and reproduces, is anticipated to assist potato scientists in improving yield, quality, nutritional value and disease resistance of potato varieties. More importantly, the potato genome sequence will permit potato breeders to reduce the 10-12 years currently needed to breed new varieties.
The PGSC was initiated in January 2006 by the Plant Breeding Department of Wageningen University & Research in the Netherlands and has developed into a global consortium of research groups from 14 countries.
 New Zealand’s Plant & Food Research is an original partner in the PGSC and leader of the work is Dr
Jeanne Jacobs who is also a member of the PGSC steering committee. Dr Jacobs says New Zealand will benefit from the genome sequencing as scientists gain insights into the genetic control of important attributes including disease resistance, nutritional value, colour and flavour.
“If you know exactly which part of the chromosome holds the genes for a particular trait, then you can precisely target crop improvements using molecular markers and so speed up breeding,” she says. “The research is also yielding genetic information important to the improvement of other crops that share some of their DNA sequences with potatoes,” says Dr Jacobs.
The potato genome has 12 chromosomes and is estimated to be 840 million base pairs. At the onset of the project, the PGSC employed an approach in which the work was allocated to each consortium member based on chromosomes and was focused on the diploid line RH89-039-16 (RH) of cultivated potato, Solanum
tuberosum. However, in the past two years, the advent of new sequencing technologies led to a significant change of approach within the PGSC and in 2008, the consortium initiated sequencing of the doubled monoploid DM1-3 516R44 (DM) potato derived from a diploid landrace of potato in order to simplify and complement the RH effort. In June 2009, PGSC members came together in Carlow, Ireland to plan the final phases of the project.
Currently, the PGSC is busy with finalising the sequence data for both RH and DM with an end goal of a high quality draft sequence of both of these potato lines by the end of 2009. Currently, genome coverage is greater than 70X using a combination of data generated by using three different sequencing platforms including two of the Next Generation Sequencing Platforms. The assembly, which covers 95% of the genes in potato, was possible due to a newly developed computer program by the Beijing Genomics Institute, a member of the PGSC from China.
This first draft genome assembly is now available in the public domain at www.potatogenome.net and updates will be made over the next six months as
additional data is generated including annotation of the genes, analysis of when and where they are switched on and off, and analysis of specific suites of genes that are critical to potato production.
A complete listing as well as contact details for all PGSC members can be found at www.potatogenome.net

 Iodine
deficiency stunts intelligence (9 Sep 09)
New research shows the intelligence of many kids in the past generation of New
Zealand children may have been stunted. In the first study of its kind, Otago
University researchers have now shown that giving children a little more iodine
to correct a mild deficiency in their diet measurably boosts their intelligence.
The findings have just been published online by the American Journal of Clinical
Nutrition. Mild iodine deficiency has been an increasing problem in New
Zealand over the past two decades and may be preventing children from attaining
their full intellectual
potential, said researcher Sheila
Skeaff. "While children eating fortified bread should benefit through
improving their iodine status, those who do not eat it should be taking steps
to increase their
iodine intakes in other ways," she said. Bread manufacturers have until this
month to comply with new regulations requiring the use of iodised salt. Skeaff
said salt used in the home should also be iodised. "Parents should also consider
giving children who do not eat commercial breads an iodine-containing multimineral
supplement," she said today. The Government last month rolled over on proposals
to add folic acid to bread to reduce the number of babies born with neural tube
defects such as spina bifida. Skeaff, principal investigator at the university's
department of human nutrition, said "Our findings ... show that the new era of
mandatory fortification of most bread with iodised salt is a good move ... which
may reap even greater benefits than initially thought." Food Standards Australia
New Zealand (FSANZ), has reduced the concentration of iodine in iodised salt
from 25mg-65mg per kg to 20mg-45mg, but required it to be used in baked cereal
products - bread, breakfast foods and biscuits.

 Butter
key to eczema control? (9 Sep 09)
Sufferers of eczema are often encouraged to avoid dairy foods, but now researchers
are to feed children enriched butter in a bid to alleviate the condition. Researchers
from Auckland and Otago universities will look at whether the spread, enriched
with linoleic
acid and eaten in small amounts as part of a normal diet, could help
ease eczema, which causes itchy, flaky skin. The acid substance is believed to
have anti-inflammatory properties. More than 100 children will be given butter
in a search for better protection to combat the onset of eczema. The researchers
are looking to recruit 50 children aged between two and 16 in the Wellington
region the rest will come from Auckland. Half will be given a single slice of
bread per day for six weeks with the specially enriched butter, and half will
be given normal butter.
One of the lead researchers, Peter Black, said eczema affected
up to 20 per cent of children in New Zealand. "We know it must be something to
do with our lifestyle, and another possibility is that changes in the diet are
involved. "In the last few decades there has been an increase in the consumption
of margarine and decrease in the use of butter." More at The
Dominion Post.
 Research
unlocking manuka honey’s secrets (3 Sep 09)
New research on New Zealand's world-famous antibacterial manuka honey has
unveiled another of its secrets. Watson and Son, a major New Zealand producer
of manuka honey, in collaboration with Professor Peter Molan of
Waikato University’s Honey Research Unit, has commissioned research by
a specialist research laboratory in Singapore, which shows that a specific
molecule acts to augment the antibacterial activity of methylglyoxal in
the honey – a process known as synergy. The unique type of antibacterial
activity in manuka honey was discovered in research at the University of
Waikato in 1982. Evidence shows manuka’s special antibacterial properties
are effective at healing wounds, but research also shows that this activity
is present in only some manuka honeys.
Last year, Waikato University Associate Professor Merilyn Manley-Harris of
the Chemistry Department, showed that methylglyoxal was responsible for the antibacterial
activity in manuka honey. However Prof Molan has long maintained there is also
a synergy at work in the honey and last October, New Zealand beekeeper-chemist
Denis Watson commissioned a specialist research laboratory in Singapore to investigate
several active fractions in manuka honey. Mr Watson is one of New Zealand’s largest
manuka producers. In partnership with iwi groups in the Far North he has more
than 15,000 beehives in manuka plantations around New Zealand. Dr Manley-Harris
and Prof Molan say they are delighted companies are taking the initiative to
commission research of this calibre. The results have proven the existence of
a formerly secret synergist: a special molecule that combines with the methylglyoxal
molecule and other fractions in the honey to create the very powerful antibacterial
activity the honey is world famous for. The discovery is also the key to understanding
why the clinically proven antibacterial activity is so effective and why international
research to date has shown that bacteria fail to develop the resistance that
is inevitable with conventional antibiotics. Research is now underway in a special
project between Waikato University’s Honey Research Unit and Watson and Son to
confirm the mode of action of the synergist and to further understand its interaction
with other fractions including methylglyoxal. This latest research will provide
the medical industry with a full scientific understanding of the antibacterial
properties of manuka. This research has huge relevance to the vitally important
active manuka honey industry, says Prof Molan. “The industry is now worth in
excess of $100 million in export earnings, but not all manuka honeys are equal
and the way to test potency has been an issue for some time,” he says. “My original
assay uses a simple test method of comparing the bacterial kill-zone of a honey
sample to the kill-zone of a standard antiseptic (in this case phenol). For a
variety of reasons this can’t be perfect and is open to interpretation and a
margin of error. The ideal objective is to have a simple analytical chemical
test that can be carried out by any lab anywhere in the world. But such a test
isn’t possible until we know what we’re trying to measure. Discovering the synergist
was the key,” Prof Molan says. “Our work now includes developing an algorithm
to find the strength of a honey’s antibacterial activity by measuring the level
of the synergist and the level of methylglyoxal present. It will then be possible
to very precisely determine the non-peroxide activity of manuka honey (the 'original
manuka activity') by chemical analysis.” Meanwhile, WaikatoLink, the research
commercialisation division of the University of Waikato, will launch a new global
consumer standard for manuka honey later this month. The standard will give consumers
complete assurance as to what they’re buying and will use Prof Molan’s name,
says WaikatoLink Commercial Manager Fraser Smith. “Professor
Molan is acknowledged as the discoverer of active manuka honey. He was awarded
the MBE for his work and is arguably the most published honey scientist in the
world. Consumers know and respect him and his work. Putting his name on the standard
and on the jar makes sense and gives consumers surety about what they’re getting”,
Mr Smith says.
 Massey
microbrewery to host craft brewing course (3 Sep 09)
New Zealand’s first residential short course in craft brewing will be held at
the Massey University Manawatu campus in November. Dr Peter Aldred and Dr
Frank Vriesekoop from the University of Ballarat in Australia will run
the course. Institute of Food, Nutrition and Human Health head Professor Richard
Archer says craft brewers have been clamouring for a short course since the University’s
microbrewery was opened in April last year. “The Brewers Guild of New Zealand
has been particularly keen that we mount a good short course,” Professor Archer
says. “This is it!” Course participants will learn about brewing raw materials,
malting and malts, hops and hop utilisation, brewery engineering, fermentation
and sensory evaluation, yeasts and spoilage organisms, hygiene and sanitation.
The course includes field trips and a final course dinner. Ballarat University
has been teaching brewing since 1971 and its short course is popular with Australian
brewers and maltsters. “Ballarat and Massey together can offer a hybrid course
tailored to New Zealand craft and microbrewers,” Professor Archer says. The first
course will run from November 6-11, starting with an introduction
and initial sensory evaluation session. It is limited to the first 16 people
registering. Participants will stay in at the Institute of Sport
and Rugby facilities.
 Caffeine
drinks may hurt teens (1 Sep 09)
Teenagers guzzling caffeine-loaded "energy" drinks might be causing
themselves long-term damage, research shows. A Canterbury University master's
project by Nika Anderson investigated the effects of caffeine consumption on
adolescent brain development in rats. During middle and later adulthood, the
27 male and 27 female rats treated with
caffeine were "probably more emotionally reactive" than the untreated control
rats.
They were less mobile and defecated and urinated more than the other rats. "Overall,
the results suggest that exposure to caffeine during adolescence produces some
small but significant increases in emotionality in adulthood," the study said.
The findings "may have clinical implications", because it was possible that adolescents
exposed to caffeine would also show increased anxiety later in life. A further
study this year had raised concern about energy drinks having a high potential
to cause acute caffeine toxicity. A Wellington schoolgirl last month collapsed
and needed to be treated by paramedics after she drank a high-powered energy
drink bought from a dairy opposite her school. The New Zealand Food Safety Authority
(NZFSA) is investigating the legality of
an "energy shot" drink with twice the caffeine of an average cup of coffee. Public
health nutritionist Bronwen King said too much caffeine could increase calcium
excretion, compromising bone growth. "This puts heavy users at risk of osteoporosis
later in life," King said. "As well, it affects concentration of kids in the
classroom, thus compromising
learning and cognitive development. "Energy" drinks are also high in sugar
and kilojoules that are not easily burned off and therefore contribute further
to
overweight and obesity." More at The

 AgResearch,
Fonterra, Massey University and Plant & Food Research collaboration launched (13
Aug 09)
Prime Minister John Key launched the Food Innovation New Zealand
(FINZ) initiative in Palmerston North yesterday. The Food Innovation
NZ initiative is a collaboration between the University, AgResearch, Plant & Food
Research, Fonterra, the Bio Commerce Centre, and the Riddet Institute (a
Government-funded Centre of Research Excellence hosted by Massey University),
supported by the Palmerston North City and Manawatu District councils.
It aims to dramatically increase New Zealand’s capacity in agri-food
innovation and enable the industry to better perform in domestic and international
markets. Massey vice-chancellor Steve Maharey said the
Food Innovation NZ partnership aimed to double the $22.9b export value
of food in 10 years. “Powerful underpinning food science will be created
by teams of scientists from Fonterra, AgResearch, Massey University and
Plant & Food Research” says Dr Andrew West, Chief Executive
of AgResearch. AgResearch has a large capability in dairy and red-meats
food science, primarily based in Hamilton and Palmerston North, and now
expanding into Canterbury too. This new collaboration will supplement those
AgResearch already has with the University of Auckland’s Liggins Institute
in Pastoral Foods for Human Health and its Nutrigenomics Centre, along
with the Universities of Otago and Waikato in areas of food science and
food agritechnology. It expands AgResearch’s link with Massey University
that, to date, has principally focused on livestock health and welfare. “It
is pleasing to work more closely with Fonterra, whose continued success
is important to New Zealand” says Dr West. The new collaboration will also
have a strong focus to provide scientific assistance to multinational food
companies, many of which use New Zealand-produced food ingredients. www.foodinnovationnz.co.nz
 AgResearch
and Lincoln University announce intent to develop a joint venture (12
Aug 09)
AgResearch and Lincoln University have announced their intent to develop
a formal joint venture to secure many of the benefits identified in their
previously proposed merger. “We will provide significant, additional benefits
to farmers and food and textiles companies through a tight collaboration” says Professor
Roger Field, Vice Chancellor of Lincoln University. “Through this
collaboration we will explore a much greater contribution by AgResearch
into education and PhD supervision, and a more integrated approach to extension
education and technology adoption. Lincoln University will utilise AgResearch’s
facilities in the North and South Islands to expand its current reach and
capacity into the land-based sector”. “This is an important collaboration
for the whole pastoral foods and textiles value chains” says Dr
Andrew West. “AgResearch is the most integrated pastoral sector
research organisation in the world, with 600 scientists and technicians,
13 research farms and four major campuses dedicated solely – absolutely
solely - to pastoral farming, dairy and red-meat food companies and woollen
textiles companies, and all associated industries. This collaboration with
Lincoln University will supplement those we have with The University of
Otago in livestock physiology and in food, with The University of Auckland
in food, with Waikato University in agritechnology and food processing
technologies, and with Massey University in livestock health, in animal
welfare and in food”. Professor Field and Dr West stated that Lincoln University
and AgResearch were exploring the joint use of research facilities and
farms and co-location of activities. Work to scope and establish the detail
of the joint venture is to begin in the near future.
 Unique
science collaboration for ground breaking agri-food research (10
Aug 09)
In a collaboration of unparalleled scientific expertise in New Zealand, AgResearch and
the University
of Auckland’s Liggins Institute are seeking to discover how nutrients
in food affect animals and humans to improve body composition. “We aim to investigate
how nutrients in foods are released during digestion and how those nutrients
then affect our metabolism. The interaction between the digestion and absorption
of nutrients i.e. the energy absorbed by the body from our diet, and how nutrients
affect our metabolism is a key focus of the research. This could have direct
benefits for people as two factors important in checking obesity are the absorption
of energy from the diet, and how we metabolise that energy,” said AgResearch
Chief Executive Dr
Andrew West. “This research could also be used to achieve beneficial
outcomes in productive animals - changing nutrient absorption and metabolism
so that the animal's body composition, like the meat they produce for example,
is more appealing and healthy for consumers. This would produce significant new
market opportunities for New Zealand farmers.” The Liggins Institute collaboration
with AgResearch has resulted in the formation of the Pastoral Foods For
Human Health Research Centre. The Liggins Institute was the first large-scale
research Institute established by The University of Auckland. It is committed
to world-class biomedical and clinical research in areas of major health importance. Professor
Sir Peter Gluckman heads the Centre’s research effort. “The Centre aims
to optimise the nutritional and health-giving qualities of foods from pastoral-based
sources for human consumption,” said The University of Auckland Vice-Chancellor Professor
Stuart McCutcheon. “A major research target is novel agri-food ingredients
with human health benefits. This focus includes animal feeds, animal welfare
products, ethical animal manipulation methods, and enhanced handling and processing
of food products.” “AgResearch and the Liggins Institute are jointly developing
two key Foundation for Research Science and Technology programmes on nutritional
epigenetics and agri-foods – one centred on animal productivity and the other
on food for human health, but both sharing core methodology and key research
staff from both organisations.” “This endeavour is an excellent example of the
fields of research we created the Liggins Institute to investigate. Better understanding
of the interrelationship between genetics and nutrition is vitally important
and any insights we uncover will be significant in dealing with a range of health
and mortality issues which currently concern governments and medical professionals,” said Professor
Wayne Cutfield, the newly appointed Director of the Liggins Institute.
AgResearch’s General Manager of Applied Biotechnologies, Dr Jimmy Suttie,
said the collaborative nutritional epigenetics research is a ground breaking
partnership in agri-food research for human health and animal productivity. “AgResearch
is the most integrated pastoral research organisation in the world. Our scientific
expertise, together with that of the Liggins Institute, provides an unparalleled
combination of capability in pastoral agriculture, agri-foods, human nutrition,
growth and health. Our work together is part of the exciting new era in agri-food
research for New Zealanders and the agricultural sector.”
 AgResearch
General Manager Food & Textiles Group appointed (28 Jul 09)
AgResearch has appointed Professor Warren McNabb as Science
and Technology General Manager of its Food & Textiles Group. AgResearch
Chief Executive Dr Andrew West says he is pleased to confirm Professor
McNabb in this important leadership position in the Institute. “Professor
McNabb will lead our scientists and technicians in rumen and livestock
metabolic sciences, and in science and technology directly supporting New
Zealand's dairy and red-meat food, and textile industries. AgResearch has
substantial capacity in food and textiles sciences that Professor McNabb
will develop further…,” says Dr West. Professor McNabb has until now been
Section Manager of Food, Metabolism & Microbiology at AgResearch. He also
holds an appointment at Massey University as Adjunct Professor at the Riddet
Institute.
Based at AgResearch’s Grasslands campus in Palmerston North, Professor McNabb
has been with AgResearch for 16 years, joining as a Research Scientist in the
then, Nutrition & Behaviour Group. Previously he was in Australia at CSIRO Division
of Plant Industry in Canberra where he was a CSIRO Postdoctoral Fellow working
on expression and manipulation of genes affecting the nutritive value of pasture
legumes. Educated at Massey University his PhD was in animal science where he
majored in nutrition and metabolic physiology. Professor McNabb is also a Fellow
of the New Zealand Institute of Agricultural and Horticultural Science and a
Professional Member of the New Zealand Institute of Food Science and Technology.
Professor McNabb’s new position as Science and Technology General Manager of
the Food & Textiles Group is one of the three Science and Technology General
Manager roles on AgResearch’s seven-member senior management team.
 Work
gets under way on biotech startup laboratory (28 Jul 09)
Work on a $30 million laboratory for start-up science companies begins
today, promising new inventions in food, medicine and environmental protection.
Auckland City Mayor John Banks will launch construction work on a purpose-built
addition to the University of Auckland's Institute
for Innovation in Biotechnology, on the corner of Symonds St and Waterloo
Quadrant.
The building will be an "incubator" for start-up biotechnology businesses that
might not otherwise be able to afford the latest technology. It is expected to
more than double the number of science companies working alongside University
of Auckland scientists under an existing programme from five to a dozen or more.
The new building is being paid for by the university ($20 million) and the Government
($10 million). Biotechnology companies have committed a further $10 million to
carry out research at the institute under a dollar-for-dollar science investment
partnership with the Government. Biotechnology has been earmarked as a growth
export industry for New Zealand, and in May scientists argued the Budget should
have allocated more money to new research. Institute director Professor
Joerg Kistler said there were three big growth areas for designing new
products - food, health and methods of cleaning up the environment. More at NZ
Herald.
 Concern
over high salt content in our food (22 Jul 09)
New research shows that New Zealanders are being fed much more salt in popular
processed foods, than people in other countries. Over 260 products, including
fast food and breakfast cereals were compared as part of the research. The research
found New Zealand to be high amongst countries with the most salt added to food. "In
our modern society we consume about nine grams of salt a day which is far too
much," says Rob
Walker from the Dunedin School of Medicine. The health group, World
Action on Salt and Health, says a KFC fillet burger, has the highest amount of
salt, nearly 3.7 grams, compared to the same burger in Australia and Malaysia.
There is more salt in Kellog's All Bran cereal in New Zealand than in America,
but not nearly as much as in Canada. And a six inch Subway fares worse in New
Zealand, too, with nearly twice as much salt as its Finnish counterpart. "Most
people are not aware of just how much they are consuming about 80% to 90% of
the salt in our diet comes through the processed food, what we add on with the
salt shaker in our meals is really only a small proportion of our daily intake
of salt," says Walker. The study says it is hypocritical of manufacturers to
make healthy claims about their products when salt is a major factor in cardiovascular
disease. More at TVNZ.

 New
research highlights sports recovery potential in blackcurrants (22
Jun
09)
A preliminary study by the New Zealand Institute for Plant & Food Research suggests
that natural chemicals found in blackcurrants may help balance the impacts exercise
can have on the body. Researchers have found signs that an extract derived from
New Zealand-grown blackcurrants - taken in capsule form before and after exercise
- has three potential effects: minimising muscle damage by modulating oxidative
stress, modulating inflammation and potentially enhancing the body’s natural
defenses against disease. The findings are published in the ‘American Journal
of Physiology – Regulatory, Integrative Comparative Physiology’. Negative
impacts from sustained sports training is a growing health issue. While exercise
is universally agreed to be healthy, extreme exercise – such as intense pre-event
training - can have some drawbacks, including lowering the body’s immune defenses
and the increasing risk of muscle damage.
The Plant & Food Research study, lead by Dr Roger Hurst, looked
at untrained individuals undergoing moderate exercise. It showed that those who
took the blackcurrant extract exhibited reduced markers for oxidative stress
linked to muscle damage and inflammation as well as increased activity linked
to immune response. “In our research, we chose a group of ten healthy everyday
people with a wide age range who exercised regularly and measured biochemical
indicators to assess the effect of taking the blackcurrant extract capsules before
and after exercise,” says Dr Hurst. “We found changes in the levels of biomarkers
that indicate antioxidant activity, inflammation modulating ability and a support
for the natural immune responsiveness to potential pathogens.” The positive link
between blackcurrants and exercise has been previously highlighted in studies
in Japan where scientists evaluated the ability of NZ-grown blackcurrants to
reduce inflammation in muscle groups related to sustained computer use and keyboard
typing. This Japanese research flagged the potential of blackcurrants to reduce
lactic acid build-up in muscles.
Dr Hurst says Plant & Food Research is yet to determine exactly what blackcurrant
compounds cause the observed effects, but he doubts Vitamin C is a factor because
the extracts tested contained only very low levels of the vitamin. “We’re looking
more closely instead at the role of flavanoids within the fruit. Flavanoids are
antioxidants, including anthocyanins, the compounds that gives blackcurrants
their brilliant black-red colour.” New Zealand-grown blackcurrants are known
to contain high levels of anthocyanins, which may be linked to the cultivars
grown here or to environmental conditions. The study was undertaken and funded
by Plant & Food Research in support of a wider research programme called ‘New
Berries’ funded by the Government and the New Zealand blackcurrant industry.
This programme investigates the antioxidant and immune supportive properties
of berryfruit and berryfruit products. It aims to use this knowledge to breed
elite New Zealand berries with assured health-promoting properties that will
have multiple end-uses including the development of functional foods.
Plant & Food Business Manager for Food Innovations Karl Crawford says the paper
has generated strong interest from industry and has also highlighted new areas
for further research. “This is early stage research, which by its very nature
often raises as many questions as it answers. That is certainly the case here.
We know we’re on the right track in our belief that fruit extracts, combined
with exercise, can have a beneficial effect on human health. In essence, this
latest study is predictive – it is showing us where we need to look if we want
to really maximise the health potential of fruit. “We know fruit and vegetables
are good for us, and science obviously has an in-depth understanding of fruit
composition and the potentially beneficial effects of fruit compounds at a cellular
level. This paper is part of one of the fastest growing areas in food and health
research – looking to build knowledge that links those two areas of established
science. It is exciting for consumers because the link for them will come in
the form of new functional food products that deliver a proven, specific benefit
to their health and wellbeing. “We’re talking about the potential to focus wellness
benefits from foods. That means moving from, say, broad claims about potential
antioxidant function toward far more specific information about benefits and
the mode of action behind them.” Note: Today, Monday 22 June, international health
and nutrition experts will discuss this and other advancements in functional
food science at the Inaugural Plant & Food Research Functional Foods Symposium.

 Price
of milk has implications for our kid's health (19 Jun 09)
Researchers at the University of Otago Wellington say that the
high price of milk and other dairy products over recent years is detrimental
to the health of children and has contributed to greater health inequalities
in New Zealand.
In a wide ranging case study published in Globalisation and Health Dr
Louise Signal and Moira Smith, from the Department
of Public Health at the University, have examined the health impacts of deregulation
of the market for milk since the 1980’s, and the impact on the nation’s health.
They say it is clear from a series of legislative changes that deregulation of
the milk market since the 1980’s has significantly reduced accessibility and
affordability of milk products for many low income families and their children. “What
we have seen is a relatively rapid increase in the price of milk, with trade
being the main priority of successive Governments since the 1990’s, rather than
the provision of milk to every household at an affordable price,”says Moira
Smith. “It means that milk, a basic nutritional product, fundamental to children’s
health, is often outside the reach of low-income families.” The researchers say
that despite payouts to farmers plunging from around $7 per kilogram of milk
solids to around $4.55kg, the retail price for two litres of milk ($3.21) is
the same as a year ago when adjusted for the CPI. Meanwhile the price of two
litres of soft drink has stayed much the same at around $2.00
for 1.5 litres. “Half a century ago governments supported the right of every
child to cheap milk at home. Now this has been removed and serious health inequities
have developed in New Zealand, particularly amongst lower socio-economic groups
and Maori and
Pacific peoples, 30% of whom fall into the lowest income group.” The researchers
point to a series of actions by successive governments: the removal of government
subsidies and control of the milk industry, the axing of price control, the application
of GST on food, and the linkage of retail prices to international commodity prices
(globalisation). This has resulted in an escalation in the price of milk for
New Zealanders, in a country where 25% of export income is earned from dairying.
Now only 38% of children drink milk daily, and 34% weekly, with 17% not drinking
it at all. The obvious solution according to the authors is for the Government
to reconsider
interventions to make milk more affordable for families. • Implement price control
or subsidies and not rely on a relatively uncompetitive domestic market to constrain
prices • Government assistance to low income families to ensure they can afford
to buy
healthy food • Milk as part of a ‘Breakfast in Schools’ programme in schools
in low-income
areas • Reduce or eliminate GST on healthy food choices such as milk and fresh,
non-processed
food.
 Researcher
develops free-range egg test (16 Jun 09)
A researcher has developed a technique to identify the difference between
eggs from caged hens and those from free-range and organically raised hens.
It is believed to be the first time that eggs from different farming systems
have been distinguished by using isotope analysis. While it is not something
the supermarket shopper could use every day, it has potential within the
egg industry to avoid mislabelling. Karyne Rogers, of
Geological and Nuclear Science's National Isotope Centre in Lower Hutt,
compared different brands of off-the-shelf eggs from cage, barn, free range
and organic farming regimes. Using isotope analysis, she found almost all
the eggs could be differentiated by relating the carbon and nitrogen found
in the egg to the hen's diet. This was possible as diet directly reflected
the type of farming environment where the hens were raised, Dr Rogers said. "Free-range
and organically farmed hens normally have access to a wider range of food
sources than caged hens, such as insects, vegetation or organic feeds,
and this changes the isotope fingerprint of their eggs," she said. The
findings, recently published in the Journal of Agricultural and Food
Chemistry, showed isotope analysis was a potentially useful technique
for identifying eggs from different farming regimes. More at NZ

Partnership
model agreed as best future for AgResearch and Lincoln University (8
Jun 09)
Three months of investigation by Crown Research Institute AgResearch and
Lincoln University have identified that a partnership model would be preferable
to a full amalgamation as it will be more cost effective and still achieve
significant benefits for New Zealand. The two organisations will remain
separate entities but focus on working much more closely together on a
range of partnership initiatives. AgResearch and Lincoln University announced
in March a combined consultative approach to investigate how they could
work more closely to develop land-based research and education through
investigating the option of a merger. The two organisations worked closely
and effectively in identifying the opportunities a new entity might deliver
and during this process it became clear the significant benefits to New
Zealand could be most cost effectively delivered from a partnership rather
than an amalgamation. A number of synergies and benefits of closer collaboration
between the two organisations have been identified through the investigation
process and it has been agreed to pursue a substantial partnership, the
form of which will be agreed in the near future. AgResearch Chairman Sam
Robinson says the joint investigation of the benefits of Lincoln University
and AgResearch working together has produced a better understanding of
the respective capabilities, strengths and expertise of the two organisations. “We
can see the potential for forming productive partnerships in post-graduate
supervision, commercialisation activities, and extension teaching,” he
says. “Knowledge transfer, through a sustainable partnership particularly
focused on technology adoption by the land-based sector is our best shared
path for the future.” Lincoln University Chancellor Tom Lambie says “We
are looking forward to a closer working partnership with AgResearch. I
believe this will still deliver significant benefits for the land-based
sector.”
 Supermarket
discounts favour unhealthy foods: study (27 May 09)
Supermarket shoppers may be encouraged to buy sugar-filled, calorie-rich drinks
by discounts and promotions, according to New Zealand research. A study, published
in Nutrition & Dietetics by Wiley-Blackwell, found healthy drinks were
less likely to be discounted in supermarkets. And the amount of the discount
was greater on products higher in fat, sugar and energy. The researchers looked
at about 1,500 discounts over a month in four supermarkets across Wellington.
They found only 15 per cent of all the non-alcoholic drinks discounted were classed
as ‘healthy’. ‘Our study shows healthy drinks are discounted less often than
unhealthy drinks. But there are more unhealthy drinks available in supermarkets
and this may explain
some of the difference,’ said author Dr Louise
Signal from the University of Otago. ‘Given the influence discounts
can have on what shoppers purchase, supermarkets could promote healthy options
by discounting the products that are nutritious and contain less saturated fat
and added sugar’ said Claire
Hewat, Chief Executive Office of the Dietitians Association of Australia
(DAA). She said this would encourage shoppers to purchase healthier choices at
the supermarket and would be an important step in addressing overweight and obesity.
As part of its comprehensive obesity strategy, DAA is calling for healthy food
to be more readily available and affordable for all Australians, tighter government
regulation of food marketing, and clearer nutrition information on food labels.
Beverages classed as ‘healthy’ in the study were water, plain reduced-fat milk
and plain reduced-fat soy beverages. And those in the ‘unhealthy’ group included
sweetened carbonated beverages, sports beverages and flavored waters and cordial.
 New
study: diet
more important than exercise (25 May 09)
New Zealanders' expanding waistlines have far more to do with overeating than
with lack of exercise, a controversial new study contends. The international
research has highlighted the disagreement over the causes of the obesity epidemic.
The study, based partly on United States food supply statistics, calculated that
the average weight of adults today should be 10.8kg more than 30 years ago. In
fact it was 8.6kg more in the US and the increase in New Zealand would be similar,
said a study author, Professor Elaine Rush, of the Auckland
University of Technology. The authors believe increases in physical activity
may have prevented people gaining the full 10.8kg. The study used medical sample
results from more than 2000 people, including 111 New Zealanders, to find the
energy-burning rates needed to maintain stable adult weight and normal child
growth. Professor Rush said the study showed how much the population - especially
in the most-deprived areas, where obesity was more prevalent - needed to cut
back
to return to the average weights of the 1970s. "Children would have to cut their
intake by about 350 calories a day - equal to one can of fizzy drink and a small
chocolate bar, and adults 500 calories - the equivalent of a large burger." Similar
results could be achieved by children walking for an extra 150 minutes a day
and adults an extra 110 minutes, but this was unrealistic, she said. More at NZ

 Cow’s
milk allergy in NZ children - new study to be launched (22 May 09)
A new pilot study will be launched into Plunket to investigate just how many
Kiwi children could be suffering from Cow’s Milk Protein Allergy and its affect
on their growth and development.
The research programme known as “The burden of food allergy” will be led by Auckland
University Professor Rohan Ameratunga, a specialist in adult
and paediatric allergies. Professor Ameratunga says he consults with at least
six new sufferers each week and international studies have shown that among infants
with Cow’s Milk Allergy,
92% have two or more symptoms. “Cow’s Milk Protein Allergy or CMPA is certainly
pretty common in New Zealand and I have noticed the numbers are increasing. I
hope our study will shed some more light on the prevalence of this condition
among Kiwi infants.” The research study, funded by the Auckland District Health
Board, will investigate
the number of children suffering cow’s milk protein allergies along with common
symptoms and severity.
Cow’s milk is one of the most common causes of food allergy in infants affecting
one in 50 children. It is caused when the immune system reacts to the protein
in milk, says Professor Ameratunga. Reactions can vary and may include; swelling
of the lips, face or eyes, hives,
welts, tingling in the mouth, wheezing or eczema. “Other gastrointestinal symptoms
can include reflux, vomiting, diarrhoea, and poor weight gain. In extreme cases
patients can experience anaphylaxis which severely affects the respiratory and
cardiovascular systems, he says. “At least 10% of the Cow’s Milk Allergy patients
I see would suffer from anaphylaxis,” says Professor Ameratunga. Registered Dietitian
Tara Chaplow, whose son also suffers from multiple food allergies welcomes the
new study.
She is concerned at the number of Cow’s Milk Allergy cases which may be going
undetected and the affect the allergy may be having on infants’ ability to thrive. “Often
the first sign of a Cow’s Milk Allergy will present when an infant is weaned
from breast milk to solid foods and formula. Their inability to process dairy
products derived from milk or any other foods containing milk affects their protein,
fat and micronutrient intake and impacts their growth,” says Chaplow. Chaplow
says this growth should be carefully monitored and cow’s milk substituted with
other foods or suitable formula to ensure children are meeting the dietary requirements
for their age group.
Parents concerned about cow’s milk allergies should consult their GP or Paediatrician.

 Pet
food research consortium launched (8 May 09)
A research consortium that aims to make New Zealand globally recognised
as the leader in innovative meat science for pet care, will be launched
by AgResearch, Mars and Massey University in Wanganui,
today. Protein Innovation New Zealand (PINZ) will be dedicated
to consolidating the important work carried out by Mars and AgResearch
in 2008. A Memorandum of Understanding will be signed by the three parties
in the presence of David Carter, Minister of Agriculture,
Forestry and Biosecurity. The project began in 2007 when the Foundation
for Research, Science and Technology identified AgResearch as the solution
to Mars’s challenge of delivering a premium pet food product to boost New
Zealand’s export markets. The Foundation has provided initial project funding
of $188,000 through its TechNZ business programme. AgResearch has extensive
knowledge and expertise in the field of added-value meat products. This
collaborative project has assisted Mars in enhancing the aesthetics and
palatability of Whiskas' cat food, manufactured at their Wanganui facility.
The result is a new premium pet food range – Whiskas' Tasty Textures -
which has been enthusiastically received over the Tasman. The range now
includes seven different products, which are exported to Australia and
look set to generate annual benefits of over $2 million for the New Zealand
economy. The success of this phase has secured internal funding from AgResearch
and Mars to continue the project over a two-year period in conjunction
with Massey University, which has the only independent Feline Nutrition
Unit in the Southern Hemisphere. The consortium’s mission is to better
understand the protein interactions and nutritional contributions of raw
meat materials and how this knowledge can contribute to the development
of highly nutritious pet foods that are clearly differentiated and compete
successfully in global markets. Erica Nicholls, the Foundation’s
Group Manager (Investments), says the Foundation’s decision to support
the project was based both on Mars being able to commercialise unique New
Zealand science quickly through its extensive channels to market, and on
the significant economic and social benefits, particularly to the Wanganui
community. “The consortium is an excellent example of businesses working
successfully alongside researchers from universities and research organisations,
and the partnership promises further significant benefits in animal and
human nutrition as well as in health sectors,” she says. It is hoped that
further funding from AgResearch and Mars will ensure that the PINZ group
can make inroads into a more fundamental understanding of raw meat materials. “And
it is expected that the new group’s research will lead to more specific
projects in the future with the goal of further developing export opportunities
for New Zealand,” says Jonathan Cox, Product & Innovation
Manager, Mars Petcare.
 AgResearch
and Liggins Institute form new nutrition research centre (5 May
09)
In a move to optimise the nutritional and health-giving qualities of foods from
pastoral-based sources for human consumption, AgResearch has put the official
seal on a collaboration with The University of Auckland’s Liggins Institute,
which will maximise research revenues from public good and industry sources.
Known as the Pastoral Food For Human Health Research Centre,
the aim of the collaboration is to carry out quality research in human nutrition
including determinants of body composition, development and metabolism. It will
exploit synergies between the two parties relating to research at the human/animal
interface, and will place priority on scientific excellence and a research programme
that is informed by, and relevant to, the needs of the pastoral, human health
and human nutrition sectors. The type of products targeted include novel ranges
of food ingredients that deliver human health benefits, animal feeds, animal
welfare products, ethical animal manipulation methods, and smart ways of handling
and processing food products. Its ultimate goal is to commercialise the resulting
research data. The Liggins Institute was the first large-scale research institute
established by The University of Auckland. It is committed to world-class biomedical
and clinical research in areas of major health importance. Professor
Peter Gluckman, who is spearheading the collaboration, is one of the
Institute’s founding directors and an award-winning expert on how discoveries
in biomedical research can be turned into improvements to long-term health. Commenting
on the newly-formed Centre, Dr Jimmy Suttie, AgResearch’s Applied
Biotechnologies Group General Manager, says “this Centre formalises a collaboration
that has taken place for many years. It allows AgResearch and the Liggins Institute
to examine holistically the interface between producing animal-based food, and
then using that food for the health and nutrition of humans.” “The combination
of capability in pastoral agriculture and human nutrition, growth and health
is unparalleled in New Zealand, and the creation of the Pastoral Food For Human
Health Research Centre dovetails neatly with the proposal for AgResearch to amalgamate
with Lincoln University, because this new entity will have access to research
capability with a wider range of foods,” he added.
New honey standard will sweeten producer earnings (24
Apr 09)
Waikato University’s Honey Research Unit is about to launch a new world-wide
standard to test manuka honey for its unique antibacterial activity, potentially
earning honey producers thousands of dollars more per drum. Waikato University
first discovered that the antibacterial properties in manuka honey are
effective in healing wounds in 1982, and the new world-wide standard will
be the first upgrade to testing for the properties since its inception.
The new test will provide more accurate and reliable ratings of manuka
honey’s antibacterial activity, and will be launched with its own trademark. Professor
Peter Molan, who heads the internationally renowned Honey
Research Unit at the university, says the existing test throws up too
many variables, with many producers losing money because of the old test. “We
know of drums of honey where the margin of error has been worth more than
$1000 and the honey producer has missed out on that because variables mean
the rating was wrong”, says Professor Molan. Developed over the past couple
of years, the new test will eliminate those variables and guarantees the
batch tested has an activity that is above the stated rating. “It’s far
more accurate, far more scientific and is quicker for the producer” says
Professor Molan. University of Waikato Vice-Chancellor Professor Roy Crawford
says Professor Molan is the most experienced person in the world regarding
manuka’s antibacterial properties. “Peter created this industry – he took
what was essentially a waste product - and his discovery and research have
made this a $100 million a year industry.” More at National
Business Review.
 Irritable
bowels could be calmed with spice (20 Apr 09)
The spice turmeric might be the magic ingredient to bring relief to people suffering
from irritable bowel disease.
Researchers at Nutrigenomics New Zealand have found that curcumin,
the major yellow component of the turmeric spice, reduces inflammation for those
suffering from irritable bowels. They said the discovery could help in the development
of diet-based treatments for people suffering from the disease. The results of
the study were published in the British Journal of Nutrition. "Crohn's
disease, a form of inflammatory bowel, can be aggravated or relieved by the sufferer's
diet," Plant and Food Research researcher Christine
Butts said. "However, due to the number of genes involved, different
people with different disease genotypes can be affected by different foods, so
there isn't a `one size fits all' solution. "Only by systematically linking particular
components to effects on the specific genotype can we get a true understanding
of the disease and how to treat it." More at www.stuff.co.nz.
 Researchers
accuse NZ of being a "laggard" in controlling the marketing of unhealthy
food to children (24 Feb 09)
Public health researchers at the University of Otago, Wellington say New Zealand
is lagging well behind other developed countries in the promotion of healthy
eating to children through the media and advertising. Their recently published
study shows that at a time when over 200,000 children in New Zealand (30%), are
either obese or over-weight, and we are facing rapidly increasing rates of diabetes,
the lack of direction regarding unhealthy food advertising is alarming. There
are 1.1 million children and young people in New Zealand potentially exposed
to this advertising on a daily basis. “The recent decision by the Government
to allow the sale of fat-laden pies and sausage rolls, and sugar-filled drinks
in schools is sending completely the wrong message to children and parents,” says
researcher Dr
Caroline Shaw from the Department of Public Health at UOW. The review
by Dr Shaw shows that there is still little or no control over the advertising
of unhealthy food to young children in New Zealand, despite the ongoing debate
about obesity. This is in contrast to other OECD countries where food advertising
aimed at children is more strictly regulated for health reasons. One of those
reasons is that international long-term studies have shown that 40-80% of children
who are obese in adolescence will remain so in adulthood. The UK has much tougher
regulations than New Zealand, and is looking at strengthening these further.
Sweden and Norway and the Canadian Province of Quebec have banned the advertising
of unhealthy food to children altogether. Dr Shaw says 70% of food advertising
on TV, in the time children watch, is counter to healthy nutrition, and that
television advertising in New Zealand supports unhealthy diets for children.
Research shows that children could easily see 7134 food advertisements in one
year if they watch TV two hours a day. Dr Shaw says there are straight-forward
solutions to the continuing marketing of unhealthy food to children, and the
growing obesity and related health problems
facing the community. • A clear Government vision which is independent from the
advertising and food industry. • More regulation or co-regulation to implement
this vision regarding unhealthy food advertising aimed at children. • Independent
monitoring of all forms of food marketing to measure success of policy interventions. • Initiating
controls over cross border marketing through international treaties.
 Fat-fighting
milk and ice cream may soon be for sale (24 Feb 09)
Fat-fighting milk and flab-destroying ice cream may soon be on the supermarket
shelves. Melbourne scientists have developed a way you can lose weight while
eating your favourite creamy treats. HealthLinx researchers have discovered milk
and dairy products contain a compound that actually stops the development of
fat cells, reduces fat cell absorption and lowers body weight. Working with Dairy
Australia the company aims to add the fat-destroying agent to milk, cheese, yoghurt
and ice cream. HealthLinx chairman Greg Rice said the protein already existed
in milk, but it had taken three years for scientists to extract it. Nutritionist
Dr Joanna McMillan-Price said evidence showed dairy products could help people
lose weight, but warned we should not mess around with our food. "We have to
stop looking for the complex scientific answers and change our life to exercise
and eat the right kind of food instead," Dr McMillan-Price said

 Carbs
are addictive, say Kiwi researchers (9 Jan 08)
Cornflakes, croissants and other carbohydrate-rich foods could be as addictive
as cigarettes, Auckland University researchers say. In fact compulsive eaters
might not be "greedy", but simply fighting addiction.
Lead researcher Simon Thornley, from Auckland Regional Public
Health Service, said heavily processed carbohydrates caused blood-sugar levels
to spike suddenly.
This "sugar rush" stimulated the same areas of the brain associated with addiction
to nicotine and other drugs.
His controversial paper, published in the journal Medical Hypotheses,
suggests the sugar content of foods can predict their "addictive potential" and
it calls for tougher regulation. Dr Thornley and his colleagues found that people
who binged on high-carbohydrate foods experienced symptoms of addiction loss
of control, a compulsion to keep taking higher amounts to get the same "buzz",
and suffering depression if they went "cold turkey". Like those addicted to cocaine
and alcohol, people with a higher body mass index had fewer brain pleasure receptors.
Speaking to Britain's Daily Mail, Dr Thornley said there was a good
case for treating highly refined foods in the same way as cigarettes banning
TV advertisements, taxing them and insisting on health warning labels. Low-carb,
high-protein diets, such as the popular Dr Atkins weight-loss regime which cuts
carbohydrates in favour of fatty foods, have been criticised by dieticians, who
say 40 per cent to 60 per cent of calories in a healthy diet should come from
carbohydrates. Good complex carbohydrates are found in starchy foods including
wholegrain breads, cereals, starchy vegetables and legumes. More at www.stuff.co.nz.
