We have established
a project team with expertise relevant to studying folates from
food composition and processing effects to bioavailability and
functionality, with funding from the European Union until August
2003.
This team, `FolateFuncHealth',
brings together both consumer and commercial interests with an
overall aim to provide folate-rich and enriched-foods with specified
and scientifically-verified consumer benefits for optimal bioavailability,
function and health. Independent nutritional scientists, biochemists,
clinicians and food technologists will work together with industry
to achieve this goal.
Why are Folates
Important ??
If
women are supplemented with folic acid during the first few weeks
of pregnancy, the incidence and reoccurrence of neural tube defects
(e.g. Spina Bifida) are significantly reduced.
Marginal folate deficiency
is also associated with elevated plasma homocysteine, an emerging
risk factor for vascular diseases and stroke, and linked to certain
cancers, notably colon.
At the present time,
our understanding of the dose-response relationships in these
situations is limited, and together with uncertainties over bioavailability,
has led to much debate over folate requirements for optimal health
and function.
Current recommendations
suggest that protection from neural tube defects can be achieved
through intakes of an extra 400 mcg daily of folic acid as supplements,
fortified foods or natural food folates. The assumption is that
all three routes of administration would have equal effects on
folate status, although this may not be the case.
