Although egg yolk is a rich source of cholesterol, the effect of eggs in raising serum cholesterol is variable and in some subjects there is no effect whatsoever. However, oxidized cholesterol can increase atherosclerosis even with normal serum cholesterol. In order to attenuate oxidation of cholesterol in eggs, it is necessary to limit the degree of heat applied. This means that we should use only soft-boiled eggs which should be almost like water. We can also avoid egg yolk altogether and get a highly nutritious egg food from the egg white alone. The saturated fats from milk products, especially butter, are highly atherogenic. There are available many butter substitutes in the form of margarines. But many of these margarines have hydrogenated vegetable oils which result in the production of trans-fatty acids. The trams-fatty acids are as atherogenic as saturated fats. There are available, however, margarines without the trans-fatty acids. These are found only in large supermarkets. Fish oils contain N3 fatty-acids which, unlike vegetable oils which contain N6 fatty-acids, can prevent atherosclerosis and sudden death by counteracting ventricular arrhythmias, acting as antioxidants, antithrombotic, anti-inflammatory agents, and decreasing triglycerides and blood pressure.
