Traditional Fats

Most primitives ate very fatty diets, so why weren't they all dying in
droves of heart disease? Because animal fat doesn't actually cause heart disease
nor does cholesterol.

Most arterial clogs are about75% UNSATURATED, with almost half being Polyunsaturated. Oils that contain a much higher amount of OMega 6 fatty acid
also contribute to atherosclerosis and cancer. On top of this we have
trans-fatty acids which are vegeteble oils that are compressed, and heated
to resemble animal fat, but unfortanetly are biochemically structured much
differently. So reach for the butter not the margarine or vegetable spread
( the actual color of margarine is grey )

Here is more information on why primitives on natural native diets
consumed fat.
