EFFECT OF DIFFERENT PROPORTION OF CARBOHYDRATE AND PROTEIN IN DIETS ON THE BLOOD GLUCOSE LEVEL OF HEALTHY MAN / 营养学报

ABSTRACT

Blood glucose level responses to different diets were examined in 12 healthy man. The test breakfasts consist of different proportion of protein and carbohydrate. Three kinds of test breakfast were fed respectively for each person. Blood glucose were measured before and 1, 2 and 4 hr after breakfast. The results indicated that high-CHO diet maintained higher level of blood glucose than other diets in 1-2 hr after breakfast. However the blood glucose level began dropping from 2 hr and dropped below fasting level at 4 hr after breakfast. The high-protein diet resulted in decreasing of blood glucose level in 1-2 hr after breakfast. The blood glucose level then increased continuously until 4 hr after breakfast.The results in this experiment showed that adjustment of the proportion of carbohydrate and protein in diets could maintain the blood glucose to a higher and stable level.
