Omega-3 May Protect Diabetics From Heart Failure
Increased intakes of Cardio-protective omega-3 fatty acids may protect
diabetics from heart failure, according to a new study from the
Netherlands.
A protective effect of high intakes of omega-3 fatty acids EPA
(eicosapentaenoic acid) and DHA (docosahexaenoic acid) was observed
according to findings published today in the European Journal of Heart
Failure.
Omega-3 fatty acids, most notably DHA (docosahexaenoic acid) and EPA
(eicosapentaenoic acid), have been linked to a wide-range of health
benefits,
including reduced risk of cardiovascular disease (CVD) and
certain cancers,
good development of a baby during pregnancy, joint
health, and improved
behavior and mood.
In this study the highest intake of marine omega-3 fatty acids linked
to a
reduction in the risk of heart failure of 33 per cent. However,
larger intakes
did not appear to offer any additional benefit.
"Scientists and health authorities are increasingly persuaded that the
intake
of fish - even in small amounts - will protect against the risk
of fatal myocardial
infarction," said nutrition investigators from
Wageningen University.
The Netherlands-based researchers recruited 5,299 men and women in 1990
with an average age of 67.5 who were free of heart failure. Over an
average of
11.4 years of follow-up a total of 669 people developed
heart failure.
Heart failure, which arises when the heart can no longer pump enough
blood
to meet the body’s needs, is the leading cause of hospitalization
among the over
65s, and is characterized by such symptoms as fatigue
and weakness, difficulty
walking, rapid or irregular heartbeat, and
persistent cough or wheezing.
The highest average intake of EPA plus DHA (over 183 mg per day) was
associated with an 11 per cent reduction in the risk of heart failure,
compared
to the lowest average intake (less than 34 mg per day), but
this was not statistically
significant.
In women, the highest intakes were associated with a 25 per cent risk
reduction,
and this was approaching significance, said the researchers.
The strongest effects were observed for diabetics, with the highest
versus lowest
intakes associated with a 42 per cent reduction in risk.
A study with older US adults, published in the Journal of the American
College of
Cardiology in 2005 (Vol. 45, pp. 2015-2021), reported risk
reduction of about
20 per cent for one to two weekly servings of fish.
“The mean intake of fish in our study was about 16 g, which roughly
equals
one serving of fish per week,” wrote the Dutch researchers.
It is possible that the type of fish consumed, or preparation methods, differs
between Europe and the USA.
