Folic acid food cuts birth defects
LONDON: Fortifying flour and pasta products with
folic acid appears to cut the number of babies born
with
congenital
heart
disease
, the most common of all birth defects,
Canadian researchers said on Tuesday. While food
fortification is not mandatory in Europe, a 1998
Canadian requirement has led to a 6 percent drop
each year in the number of such defects in Quebec,
they reported in the British Medical Journal.
"These findings support the hypothesis that folic
acid has a preventive effect on heart defects,"
Louise Pilote of McGill University in Montreal and
colleagues wrote. "Public
health measures to increase folic
acid intake were followed by a decrease in the birth
prevalence of severe congenital heart defects."
Currently 67 countries fortify wheat flour, 47 of
them by mandate, Helena Gardiner of Imperial College
in London and Jean-Claude Four on of CHU
Sainte-Justine University Hospital Centre in
Montreal noted in an editorial. Folic acid helps the
body make healthy new cells. It is important that
women get enough of it before and during a
pregnancy to prevent major birth
defects involving a baby's brain or spine. Leafy
green vegetables, fruits, dried beans peas and nuts
contain folic acid. It can be added to grain
products or taken as a
dietary
supplement. Even with
fortification, many women do not get enough folic
acid. In their study, Pilote and colleagues
identified all infants born in Quebec with severe
congenital heart defects between 1990 and 2005.
Their analysis showed no change in how many babies
were born with severe heart defects in the nine
years before fortification. But there was a 6
percent decrease annually for each of the seven
years after fortification began.The dip may seem
modest but given the complex treatment for the often
fatal heart defects, even a small reduction can
significantly reduce costs health care costs, the
researchers said.
