Plasma Lipids: Optimal Levels for Health compiles reports on optimal blood lipid levels. This book discusses the optimal levels of blood lipids that suffice for optimal physical and mental development of man while at the same time does not detrimentally affect human health. Clinical, epidemiological, and experimental evidence agrees that the ideal (optimal) serum cholesterol level for children aged 10-14 should be 120 mg% and that the ideal (optimal) cholesterol level for adults should be 160 mg%. This text stresses that if these are indeed the optimal levels, and so many people have levels far above these values, then it is evident why a large proportion of the population succumbs to cardiovascular disease. This publication is intended for physicians and scientists concerned with the optimal values of health.
