Senior citizens interested in improving their health and possibly protect against clogged arteries should turn to the animals who live under the sea.
A new study from Columbia University Medical Center contributes more evidence that adding fish to one's diet can significantly benefit their health.
Previous studies have found the omega-3 fatty acids found in certain fish can help in preventing mental illness, lower fat in the bloodstream and delay some disabilities associated with aging.
However, a new study has found a diet rich in those fish oils may also prevent the accumulation of fat in the aorta, the main artery leaving the heart.
Dr Richard J Deckelbaum, who led the study, conducted experiments with three separate populations of mice where each group was fed a different diet: a balanced one, another high in saturated fat, and a third high in omega-3 fatty acids.
It was found the diet containing omega-3 prevented LDL cholesterol (or bad cholesterol) from entering the arteries.
Omega-3 fatty acids can be found in tuna, sardines, salmon and other cold water fish.
Those who don't like fish may want to turn to nutritional supplements to incorporate omega-3 in their diet.
