Objective To investigate the effects of different medical nutrition therapy on blood glucose variability in elderly patients with type 2 diabetes .Methods Eighty‐five patients with type 2 diabetes were randomly divided into three groups ,29 cases in the control group ,27 cases in the low GI diet group ,29 cases in water‐soluble dietary fiber group .Each patient was established a individuality diabetic diet recipe according to the guidelines of medical nutrition therapy ,combined with oral hypoglycemic agents , The breakfast and dinner for patients in low GI diet group were completely instead of low GI diet ,while the breakfast and dinner for patients in water‐soluble dietary fiber group were added 10 g dietary fiber .Blood glucose ,blood lipid ,renal function and blood glu‐cose fluctuation were observed before and after one‐month intervention .Results Compared with before intervention ,the concentra‐tion of blood glucose after the intervention in each group were decreased (P < 0 .05) ,the glucose fluctuation index in low GI diet group and water soluble dietary fiber group decreased obviously after the intervention (P< 0 .05) .After the intervention ,average fasting blood glucose ,postprandial glucose average ,and mean blood glucose in low GI diet group were significantly lower than those in control group (P< 0 .05) ,Meanwhile ,the blood sugar standard deviation and MAGE in low GI dietary intervention group and in water‐soluble dietary fiber group were significantly lower than that of control group (P< 0 .05) .Conclusion On the basis of the di‐abetes diet recipes and oral drug treatment giving low GI dietary replacement therapy or adding water soluble dietary fiber ,for eld‐erly patients with type 2 diabetes ,could effectively control the blood glucose level ,and significantly reduce glucose variability .
