Fish Oil and Disease Prevention
Fish oil may reduce the risk of heart attack and improve overall
heart health. Researchers at the Vet. Affairs Medical Center report
that dha and epa, major components of fish oil, offer substantial
protection against coronary heart disease.
Their study involved over 6,000 middle-aged men.
Researchers working at the Veterans Affairs Medical Center state
that DPA and DHA, primary components of fish oil, provide substantial
protection against coronary heart disease. This study involved
more tha six thousand middle-aged men who had samples of their
blood taken between 1973 and 1976.
During the next seven years, 94 of these men had a heart attack
or died suddenly due to heart disease. The 94 men were matched
with 94 healthy men and the fatty acid profile of their blood
samples compared.
The researchers discovered that the 94 men with heart disease
tended to have a higher serum level of the saturated fatty acid
palmitic acid and stated that a high level of this acid increases
the risk of CHD by 68 percent. Palmitic acid is the main saturated
fatty acid in most diets. This acid is known to cause an increase
in both total cholesterol and low-density cholesterol levels;
the researchers, however, found that the detrimental effect of
a high intake of palmitic acid persisted even after allowing for
its cholesterol- increasing effect.
The researchers also determined that men with a higher blood
level of the Omega-3 unsaturated fatty acids, docosapentaenoic
acid and docosahexaenoic acid had an almost 50 percent lower risk
of developing heart disease than did men with lower levels. Furthermore,
the researchers found that men with CHD tended to have a higher
serum level of Omega-6 fatty acids derived from linoleic acid.
Fish Oil may reduce heart attack fatalities by balancing certain
electrical rhythms in the heart, thus preventing blood clots from
forming. George Billman, professor of physiology at the Ohio State
Univ., says that omega-3 fatty acids in fish oil make the tissues
in the muscles of the heart less susceptible to damage caused
by a lack of blood flow. It looks like omega-3 fatty acids protect
against the changes induced by ischemia, said Billman. Billman,
along with researchers at the Massachusetts General Hospital and
Harvard University Medical School, published the results of the
study in a recent issue of the journal 'Circulation'.
The omega-3 fatty acids in the study seemed to do the work of
anti-arrhythmic drugs. This work was funded by the American Heart
Association, Ohio Valley Affiliate, and the National Institute
of Diabetes and Digestive and Kidney Diseases of the National
Institutes of Health.
Dr. Barry Sears, a leading authority in the field of drug delivery
systems and dietary control of hormonal response, states that
Research is increasingly emphasizing the broad benefits of high-grade
fish oil.
