The metabolic effects of fructose incorporated in the normal diets of 13 poorly controlled, Type 2 diabetic patients were studied in a 6‐month, randomized, crossover study. Patients used 60 g day −1 of crystalline fructose in divided amounts as part of their isocaloric (1400–3900 kcal), weight‐maintaining diet. During fructose supplementation, the distribution of carbohydrate‐derived calories was 35 % complex and 15 % simple, the latter solely from fructose. This was compared with the patients' values on their usual diabetic diet (carbohydrate 50 % (mostly complex), fat 38 %, and protein 12 %). After 6 months of taking fructose, fasting serum glucose decreased from 12.6 ± 1.1 (± SE) to 9.8 ± 1.3 mmol I −1 ( p < 0.02), while it was unchanged on normal diet (11.0 ± 0.1 vs 11.6 ± 0.9 mmol I −1 , NS). Glycosylated haemoglobin was also reduced from 11.3 ± 0.4 to 9.9 ± 0.5 % ( p < 0.05) on fructose, but unchanged on the control diet (10.4 ± 0.7 vs 11.2 ± 0.7 %, NS). No significant long‐term deleterious changes were observed in the fasting serum lipids, lipoproteins, and apolipoproteins A‐1 and B‐100. Fructose was well tolerated without significant effects on body weight, or lactic acid and uric acid levels.
