摘要
Background This prospective, randomized, controlled study was designed to investigate the effects of a diabetes specific formula （Diason low energy： 313.8 k J/100 ml）, compared with a standard formula, on insulin sensitivity, serum C peptide, serum lipids and free fatty acid （FFA） in type 2 diabetics. Methods In total of 71 type 2 diabetics completed the study. Enteral formulas were given orally as the sole source of nutrition to the subjects for 6 days. Venous blood samples （0.5, 1, 2, 3 hours） were collected at day -7 after a 75 g oral glucose tolerance test （OGTT）, day 1 after a standard test meal （1673.6 k J） and after 6 days of either the test diabetes specific formula or a standard formula. Plasma glucose, serum insulin, C peptide and lipids were.measured. Results After the intervention period, the diabetes specific formula resulted in a significantly lower postprandial rise in blood glucose concentrations at 0.5 hour （P 〈0.05） and 1 hour （P 〈0.01）; significantly lower peak height of plasma glucose （P=0.05）; significantly lower plasma insulin concentrations at 0.5 hour （P〈0.01）, 1 hour （P〈0.01） and 2 hours （P 〈0.01）; and a significantly lower plasma insulin peak compared to controls; both OGTT and a standard test meal （P 〈0.05）. The glucose and insulin area under the curve after the diabetes specific formula compared to the standard formula were significantly lower. The C peptide level was lower after 6 days of both nutrition formulas compare to 75 g OGTT, but not different from the standard mixed meal. Both formulas were well tolerated. Conclusions In summary the diabetes specific formula with a relatively high monounsaturated fatty acid and high multi fiber proportion significantly improved glycemic control. On top of this, the insulin sensitivity （HOMA-IS） was significantly improved and may therefore directly improve the impact on long term complications. The disease specific formula should therefore be the preferred option to be used by d
