Abstract
1. The serum glycerides of men were raised 1–2.5 h after the ingestion of glycerol, whereas in young women given glycerol the serum glycerides were not raised. In men who had a supplementation of glycerol to their free-choice diet there was a rise in the concentration of fasting serum glycerides, a rise that was not found when a similar supplementation was given to young women.2. These findings would support the tentative suggestion that dietary fructose does not follow the Emden-Meyerhof pathway to the same extent as glucose. The increased serum glyceride levels reported after high-fructose diets may be due to an increased availability of the glycerol moiety of glycerides.
