The portfolio diet for cardiovascular risk reduction.

Prompted by current dietary recommendations for the control of serum cholesterol to new targets to reduce the risk of coronary heart disease (CHD), and by the CHD risk reduction claims made for certain foods or food components, studies are now being undertaken using combinations of cholesterol-lowering foods in one diet (eg, a dietary portfolio) rather than single foods to achieve more effective dietary control of serum cholesterol. This approach has increased the potential relevance of dietary therapy and may yield nutrition strategies that bridge the gap between what is regarded as a good diet and drug therapy.
