Abstract
The present article summarizes the effects of diets containing either cow's milk or soy protein beverage on plasma lipids and lipoproteins in children with familial hypercholesterolemia. After a stabilization period of 6 weeks without any hypolipemic medication, 10 subjects aged 6-12 years were randomly assigned to either cow's milk or soy protein beverage with subsequent crossover after a washout period, each of 4 weeks duration. During the experimental periods, subjects were fed diets containing 20% of energy as protein, of which 35% was from cow's milk protein or soy protein isolate, 28% of energy as fat with a polyunsaturated:monounsaturated:saturated fat ratio of 1:3:3, and <200 mg/day of cholesterol. The soy protein beverage, compared to cow's milk, induced significant reductions in plasma triglycerides and very-low-density lipoprotein cholesterol, as well as a significant increase in high-density lipoprotein cholesterol, indicating that consumption of soy protein beverage may be beneficial for the prevention of coronary heart disease in children with familial hypercholesterolemia.
