‘Fishy’
supplements
Most fish oil supplements sold in New
Zealand contain less omega-3 fatty acids than their labels
claim, according to research by Liggins Institute
scientists.
Analysing 32 brands of fish oil
capsules marketed in New Zealand, the researchers found that
only three contained the same concentrations of omega-3
fatty acids as listed on the label, and that most products
contained less than two thirds the amount stated.
The scientists also measured the level of oxidation in fish oil products – suggested to be an indicator of freshness – and found that over half exceeded recommended limits. Surprisingly, this was not linked to the ‘best before’ date or country of origin.
The research was widely covered by both New Zealand and international media, of which many questioned why the research paper, published in the journal Scientific Reports this week, did not reveal the names of the brands tested in the study.
Earlier this week, the Science Media Centre contacted experts for comment on the study and its findings.
“If the results are accurate, then fish oil supplements in New Zealand can be added to a long list of dietary supplements for which there are serious discrepancies between what the manufacturer claims the consumer is getting and what is actually in the supplement," says Murray Skeaff, Professor in Human Nutrition at the University of Otago.
"The researchers should publish the
brand names of the fish oils supplements that were analysed
so that consumers may be able to identify the supplements of
highest quality.”
Name and shame?
The question of
whether scientists should play a consumer watchdog role is a
tricky one. In the overseas research cited by the New
Zealand researchers one Norwegian survey of fish oil
products named the specific brands tested, whilst a
similarBrazilian study did
not.
Speaking to the media, the paper's lead author Professor Wayne Cutfield made clear his aim was to raise awareness about the sector as whole and create change at a policy level (a bill totighten up the natural products industry is currently before Parliament). In an interview with ONE News he also raised the point that some of the brands may have changed fish oil suppliers since the testing and could be unfairly vilified in the media.
Further expert commentary and a round up of media coverageis available on the Science Media Centre website.
Where are
the rock wren?
Unfounded claims 1080 poison
killed rare birds has seen DOC on the offensive this
week.
The Department of Conservation has
rejectedclaims aired by an anti-1080
campaigner in the Nelson Mailthis week, that last
year's drop of 1080 in the South Island's Kahurangi National
Park killed numerous endangered rock wren that rangers were
monitoring in the area.
Of the 39 alpine birds that DOC had identified, 25 can no longer be found. However, DOC pointed out that no dead rock wren had been found and that, notoriously reclusive, the birds are very hard to monitor anyway.
A DOC spokesman told the New Zealand Herald that there was no evidence to suggest the poison dropped to control pest numbers in the wake of the beech mast event, had killed the birds it was intended to protect.
"We don't know what's happened - whether the heavy snowfall covered the nests or something else. There is a whole host of potential scenarios," he said.
Rock wren nest on the ground making them vulnerable to pests - but also to snow cover.
Last month, the Parliamentary Commissioner for the Environment, Dr Jan Wright, praised DOC on the result of its 'Battle for Our Birds' campaign, pointing out that rat populations had "crashed dramatically" following 1080 drops.
However, she did point out that there had been some casualties among native birds, wth three of 43 radio-tagged kea dying from 1080 poisoning.
For now however, the fate of the missing rock wren, a bird species classed as "nationally endangered", remains unknown.
RMA overhaul
on horizon
The Government has revealed its plans
for a long-anticipated overhaul of the Resource Management
Act (RMA), touting changes that will lead to more affordable
housing and a better managed
environment.
A number of
proposed reforms to the RMA were this week night outlined by
Environment Minister Dr Nick Smith. Major changes
foreshadowed included the prioritisation of housing
affordability and giving greater weight to property
rights.
A summary of the proposed reforms is available here.
“These
reforms will be pragmatic and moderate,” said Dr Smith.
“We want to reduce the mountain of plans and rules that
make the RMA a barrier to new housing and jobs, but retain
the core environmental controls that ensure we keep New
Zealand special and such a great place to
live.”
The SMC collected contacted experts for
initial reaction to the proposed
reforms.
Morten Gjerde, a
Senior Lecturer in Urban Design at Victoria University of
Wellington, agreed that there was room for improvement but
urged caution.
"What we have to keep in mind is the objective of balancing current needs with those of future generations and of the environment," he said.
"I’m a little worried that the full extent of proposed changes may lose sight of this goal."
Assoc Prof Caroline Miller, from Massey University’s School of People, Environment and Planning, was circumspect about the aim of lowering housing costs through RMA reforms.
“Affordable housing will not be achieved solely through RMA reform as it is a product of a complex range of factors including the cost and availability of finance, the cost of building materials, and the availability of adequately trained builders. Changing the RMA will change none of those factors," she explained.

see the birth of an island. Visually it was quite
spectacular, but there was no big sound coming with it, no
boom. It was a bit eerie."
