FACT SHEETS
Update
on Fibre
Did
you know that a high fibre diet may not
prevent or cure constipation unless you
drink enough water every day. Some high
fibre breakfast cereals may have around
10g of fibre per serve and if this cereal
is not accompanied by enough fluid - it
may, in fact, cause constipation.
Many
Australians consume about 20g of fibre
per day - yet the recommended intake is
at least 30g per day of fibre. How easily
can this be achieved
with food? more

WHAT'S
NEW IN NUTRITION RESEARCH
Artifical
sweetener 'Aspartame' (Equal) and health
The
European Union's Scientific Committee
of Food reviewed all the scientific research
to date on aspartame and concluded that
aspartame use (even at high intakes) was
not linked to any health problems such
as headaches, epilepsy, brain tumors and
other illnesses. The report can be found
at:
http://www.foodstandards.gov.uk/mulimedia/pdfs/aspartameopinion.pdf
Portion size and obesity
Two
US studies published this year have shown
that the portion size of meals and snack
foods eaten at home and at restaurants
(including fast food outlets) in the US
have increased over the last 20 years.
It is suspected that this 'portion distortion'
may be contributing to the rising prevalence
of overweight and obesity in the US and
probably also in Australia.
Many
people are unfamiliar with recommended
portion sizes - for some a portion is
whatever fills their plate - but one serving
of cooked rice or pasta, for example,
is only 1 cup (which fills only about
one third of your plate) and one serving
of meat is about 100g (which is the size
of a pack of cards). Have a look at HECs
Healthy
Eating Pyramid for recommended portion
sizes.
The
study published in the Journal of the
American Medical Association in January
2003 by Nielsen & Popkin http://jama.ama-assn.org/cgi/content/abstract/289/4/450
reported that portion sizes for most foods
served in the home and at restaurants
in the US have increased; 93 more calories
are consumed in a serving of salty snacks,
49 calories more in soft drinks, 50 more
in fruit drinks, 97 more in hamburgers
and 133 more from Mexican food. Most of
the increases were in fast food establishments
except for hamburgers, cheese burgers
and desserts where the increases were
greater at home than outside. The only
takeaway food which didn't change was
pizza.
Another
study published in the January 2003 Journal
of the American Dietetic Association reporetd
that portion sizes increased significantly
between 1990 and 1995 for soft drinks,
coffee, tea, and ready-to-eat cereal.
The
authors concluded that it is not enough
for health professionals to recommend
the right foods to eat - we also have
to control the quantity as well.
At
the healthy eating club our recommendation
is:
"A moderate
intake of a variety of foods is the key
to
good health and environmental sustainability"
