Abstract
Two dietary comparisons were made to study the effect of natural carbohydrates on serum cholesterol concentration in man. In the first experiment, sucrose and gluten were substituted isocalorically for the carbohydrate and protein of bread and potatoes. The exchanges involved (as percentage of total energy intake) were 17 and 2% of carbohydrate and protein, respectively. In the second similar experiment, sucrose and soybean protein were substituted for leguminous seeds. The corresponding exchanges were 16 and 2% of total energy. The sucrose diet and the bread and potato diet caused identical serum cholesterol levels, whereas the diet containing leguminous seeds caused a serum cholesterol level lower by 9% than that of the sucrose diet. It is concluded that the substitution in the diet of the natural carbohydrates of leguminous seeds for sucrose produces a lowering of serum cholesterol concentration in man.
