WHAT'S
NEW IN NUTRITION RESEARCH
Colon
cancer and vegies
A
study published in the December 2003 issue
of Cancer Causes and Control on 133,000
US adults reported that men with the lowest
intake of vegetables had a 79% increase
in colon cancer incidence in the 5 years
after diet was assessed. However, men
eating the most vegetables had only a
31% reduced risk of colon cancer which
was not statistically significant. Similarly,
women with very low intakes of fruit were
also at increased risk. This study suggests
that low intakes of plant foods may increase
risk of colon cancer and reminds us that
a day should not go by without eating
vegies and fruit more......
Cinnamon,
Diabetes and Heart Disease
Studies in rats have shown that cinnamon
lowers blood glucose and cholesterol levels.
A new study published in Diabetes Care
in December 2003 (Khan et al) has shown
that small amounts of cinnamon in humans
with diabetes can lower blood glucose,
cholesterol and triglycerides. Sixty Pakistani
men and women were divided into 6 groups
and given 1, 3 or 6 grams of cinnamon
(Cassia - red brown variety) or similar
amounts of placebo for 40 days. Blood
glucose and lipids dropped on average
by 20% and remained low for 20 days after
intake was stopped. Also, the impact on
blood levels was the same at all doses
i.e there was no dose response - so 1g
was as effective as 6g. The authors conclude
that inclusion of cinnamon in the diet
of peole with diabetes will reduce risk
factors associated with diabetes and heart
disease.
(PS there is also another
variety of true cinnamon not used in this
study which is tan in colour).

Antioxidant
phytochemicals: dietary phenolics
new theory about the mechanism by which
they act as antioxidants
Chronic
diseases like diabetes, heart disease,
arthritis, cognition diseases and cancer
have been linked to "oxidation"
of "cellular molecules" such
as proteins, lipids and DNA. This is where
damaging modified oxygen molecules attach
to molecules in cells and cause damage
and inflammation. This is why "antioxidants"
have received so much media attention
because they help to prevent or remove
the damaging oxygen molecules from interacting
with cellular molecules before they cause
damage and lead to disease. Some of the
most important antioxidants are phytochemicals,
especially the phenolic antioxidants,
found in plant foods (e.g grapes, berries,
olives, soy), herbs (e.g oregano) and
spices (e.g cinnamon,cumin, turmeric).
A new theory has been put forward by nutrition
scientists (Professor
Shetty and Professor Wahlqvist which will
be published in the next issue of Asia
Pacific Journal of Clinical Nutrition
March 2004) about how these
dietary phenolic antioxidants may be using
an alternate energy producing pathway
(pentose phosphate pathway) which also
involves an amino acid (proline) to stimulate
this antioxidant response. This also means
that foods high in protein, containing
the amino acid proline and proline precursors
(e.g fish, legumes), may help support
the phenolic-linked antioxidant response.
This is an interesting theory. Until the
details about the pathway are worked out,
remember to eat a variety of plant foods,
to use herbs and spices and where possible
to eat fish and legumes more
about this theory..... more
about antioxidants more
about herbs and spices.
