[Blood glucose and insulin secretion after meals rich in simple and complex carbohydrates, in non-insulin-dependent diabetics].

In 10 well controlled non insulin-dependent diabetics, 25 g of complex sugars were replaced by the same amount of simple sugars in each of two isocaloric meals identical in their lipid, protein and carbohydrate contents. This had no detrimental effect on postprandial glycaemic and insulin responses. There were no statistically significant changes in areas under the curve and kinetics of glycaemic, insulin and peptide C responses after ingestion of limited amounts of simple sugars. It appears from these results that well controlled, non insulin-dependent diabetic patients without marked postprandial fluctuations in glycaemia (as confirmed by self-performed capillary blood tests) can be authorized to take 25 to 40 g of simple sugars (preferably fructose) during meals.
