While attaining a low blood cholesterol is considered healthy, it is only one of many factors affecting heart disease which must be considered. This publication explains more fully the relationship of diet to coronary heart disease and the health benefits of fish oil. N3 fatty acids are found mostly in fish, but are contained in other foods as well. Fish oil is the best food source of these fatty acids. Here's how it works.
Platelets are clot-forming blood cells which prevent excessive bleeding.
Overly active platelets, however, may speed the build-up of plaque, a deposit of fatty or fibrous material which narrows a blood vessel wall. Elevated blood cholesterol also contributes to the acceleration of plaque formation. When plaque narrows an artery it is easier for a blood clot to get stuck in the artery and this can cause a heart attack. Because platelets also form blood clots, this is likely to occur. That's why it is desirable to reduce platelet activity and why N-3 fatty acid, fish oil, is beneficial.
