Fats, Fish Oil and Omega-3-Fatty Acids (cont.)

What are the benefits of omega-3-fatty acids?

Scientific evidence is mounting that fish oil (predominantly omega-3-fatty acids) can reduce the risk of sudden cardiac death. Some scientists also believe that omega-3 fatty acids can improve one's blood lipid (cholesterol and triglyceride) levels and decrease the risk of coronary heart disease.

What is coronary heart disease?

Coronary heart diseases are heart conditions caused by atherosclerosis (hardening and narrowing) of the coronary arteries, arteries that supply blood and oxygen to the heart muscle. Coronary arthrosclerosis is typically silent; people can have coronary atherosclerosis for years to decades without any symptoms or signs of heart disease. Symptoms and signs of coronary heart disease develop when the diseased arteries become critically narrow or completely blocked so that they can no longer deliver adequate blood and oxygen to the heart muscle. Obesity, high blood cholesterol, high blood pressure, cigarette smoking, and diabetes mellitus can accelerate the arthrosclerosis process, and increase the risks of developing coronary heart disease. Coronary heart diseases include heart attacks, sudden cardiac death, angina, heart failure and heart rhythm disturbances.
