Some effects, in baboons, of chronic ingestion of glycerol with sucrose or glucose.

Six mature male and six mature female baboons were given fat-free diets high in sucrose or glucose together with glycerol, a chow diet with glycerol, and a fat-free high sucrose diet without glycerol. In the male animals, the concentration of triglyceride, cholesterol, glucose, and glycerol in fasting serum was significantly greater when sucrose and glycerol were given together compared with the other diets. The fasting serum triglyceride and cholesterol were significantly greater in the females on the sucrose + glycerol diet compared to the glucose + glycerol diet. It is suggested that glycerol and fructose (in sucrose) share a metabolic pathway that leads to an enhancement of serum lipid concentrations.
