OBJECTIVE: To investigate the metabolic effects of dietary fructose and
sucrose in type II diabetic patients. RESEARCH DESIGN AND METHODS: Sixteen
well-controlled type II diabetic subjects were fed three isocaloric diets
for 28 days each. The three diets provided 50-55, 15, and 30-35% of total
energy from carbohydrate, protein, and fat, respectively. In one diet, 20%
of total calories were derived from fructose; in another, 19% of total
calories were derived from sucrose; and in the control diet, only 5% of
daily calories were derived from sugars, all other carbohydrates being
supplied as polysaccharides. RESULTS: No significant differences were
observed between either the fructose or the sucrose diet and the control
polysaccharide diet in any of the measures of glycemic control, serum lipid
levels, or insulin and C-peptide secretion. CONCLUSIONS: Our data suggest
that in the short and middle terms, high fructose and sucrose diets do not
adversely affect glycemia, lipemia, or insulin and C-peptide secretion in
well-controlled type II diabetic subjects.
