Omega-3 Fish Oil Nutritional Supplements
Beneficial For Supporting Cardiovascular
Health, Reducing Risk of Diabetes and
Assisting Weight Management
Omega-3-rich supplements may improve blood lipid levels
of people with metabolic syndrome, reducing the risks of
developing serious health problems, reports a new study.
The research, published in The Journal of Nutrition, suggests
that the effects of metabolic syndrome, a major risk factor for
insulin resistance and diabetes can be reduced through the
addition of omega-3 fatty acids in low-fat, higher complex
carbohydrate diets.
“Fish oil supplements correct many metabolic alterations
associated with insulin resistance, including reduced
postprandial plasma triglyceride concentration” stated the
researchers from the University of Cordoba, Spain.
Metabolic syndrome is the name given to a group of risk
factors that frequently include obesity, hypertension, high
levels of blood lipids, and high blood sugars. The condition
is a common precursor to type II diabetes, and is also strongly
associated with increased risk of major health problems such
as heart disease and stroke.
The causes of metabolic syndrome are unknown, although
they are thought to involve both genetic and environmental
factors, including poor diet.
One way to increase the overall health and reduce the risks
of people with metabolic syndrome, has been to eat a diet
low in saturated fat and high in complex carbohydrates. However,
previous research has suggested that this diet does not help to
reduce high levels of blood lipids, with some studies observing
such a diet could even be raising blood lipid levels.
The new study looked into the effects of four different diet
combinations on blood lipid metabolism, in 117 patients with
metabolic syndrome.
In accordance with previous suggestions, the researchers found
that a low-fat, high-complex carbohydrate diet had “several
detrimental effects”, including significantly increasing total
triglyceride levels, and triglyceride rich lipoprotein cholesterol
levels.
In contrast, intake of the same diet supplemented with
omega-3 was found to have no effects on blood lipid levels,
with researchers observing that a diet rich in monounsaturated
fats, or a low-fat diet rich in complex carbohydrates and
omega-3 fatty acids, resulted in lower circulating blood lipid
levels than a diet rich in high saturated fats or a diet low in
fats and high in complex carbohydrates.
The data from the study suggest a place for higher omega-3
intake in people with metabolic syndrome, and supports previous
research that suggests monounsaturated fatty acids can have a
positive effect on blood lipid levels.
“The long-term effect of the low-fat, high-complex carbohydrate
diet, pre vs. post intervention phases, showed several beneficial
effects of long chain omega-3 PUFA supplementation,” stated
the researchers.
“Our data suggest that long-term intake of an isocaloric, low-fat,
high-carbohydrate diet supplemented with long chain omega-3...
have beneficial effects on postprandial lipoprotein response in
patients with metabolic syndrome,”
