Short Term Effects of Feeding Male Subjects with Glucose Syrup Fractions and <i>D</i>-Glucose

Abstract

Adult male volunteers were fed for 5-day periods on diets consisting of 7.5 g carbohydrate/kg body weight/day and 1.0 g calcium caseinate/kg body weight/day. The carbohydrates used were <i>D</i>-glucose, low molecular weight fraction of glucose syrup, and intermediate molecular weight fraction of glucose syrup. At least 99.9 % of all carbohydrates were absorbed and metabolised as judged by faecal and urinary analyses. All diets tended to result in a decrease in fasting serum glucose levels. Glucose tolerance tests showed peak rises above fasting level in capillary blood in the order <i>D</i>-glucose > low molecular weight fraction of glucose syrup > intermediate molecular weight fraction of glucose syrup. All fasting serum cholesterol and phospholipid concentrations dropped substantially after 5 days. Fasting serum triglyceride levels rose on the <i>D</i>-glucose and low molecular glucose syrup fraction diet but fell on the intermediate molecular weight glucose syrup fraction diet. The percentage triglycerides and cholesterol in the total skin surface lipids showed the opposite trend. Each dropped most on the <i>D</i>-glucose diet, showed less change on the low molecular weight fraction of glucose syrup and rose substantially on the intermediate molecular weight fraction of glucose syrup. Total skin surface lipids, on the other hand, rose on the <i>D</i>-glucose and low molecular weight glucose syrup fraction diets, and dropped on the intermediate molecular weight glucose syrup fraction diet.
