Portfolio diet
The Portfolio Diet is a therapeutic
Background
Heart disease is the leading cause of death in the United States.[4] Several risk factors have been identified as associated with cardiovascular disease. They include high blood pressure, high blood cholesterol, being overweight or obese, and smoking.[5] The American Heart Association (AHA) and American College of Cardiology (ACC) suggested life style management to control risk factors in order to reduce cardiovascular risk. One of the strategies is to reduce dietary saturated fat, which should reduce low-density lipoprotein in the blood (LDL) which is considered “bad” blood cholesterol.[6] If dietary and life style management proves ineffective on its own, medication is added, such as statin, to reduce blood cholesterol levels. Soy protein, nuts, viscous fibre, and plant sterols have been found to have a cholesterol lowering effect. The U.S. Food and Drug Administration has approved a health claim for these foods. David Jenkins believes that inclusion of all these foods in the diet is more effective at lowering cholesterol.
Diet
A typical portfolio diet includes a daily intake of about 50 grams of nuts (such as almonds, peanuts and walnuts), 2 grams of plant sterols, 10-25 grams of soluble fiber (from sources such as oats, barley, and psyllium), and 50 grams of soy protein.[3]
Health effects
There is high-quality evidence that the portfolio diet significantly reduces LDL-C and has positive effects on cardiometabolic risk factors.[1]
