Effects of dietary treatment on lipoprotein levels in hyperlipoproteinaemia.

Diet constitutes the basis of all lipid lowering therapy. The mechanisms responsible for the effects of the different dietary measures are not yet fully understood. Dietary treatment 'normalized' the lipid levels in over 50% of the mild to moderate hyperlipoproteinaemic states encountered in a middle-aged population with clinical manifestations of atherosclerotic cardiovascular disease. Triglyceride and cholesterol determinations in isolated lipoprotein fractions supplied additional information on the character and extent of the lipoprotein changes induced by diet.
