复合降糖乳粉（下称复合乳粉）是以脱脂乳粉为基质，强化γ－亚麻酸及锌Ｚｎ４ｍｇ％）、铬（Ｃｒ３＋）等而成。动物实验结果：复合乳粉对正常大鼠血糖无影响。灌胃第５周时，中、高剂量复合乳粉组（剂量分别６．６７ｇ／ｋｇｂｗ和１３．３３ｇ／ｋｇｂｗ）对四氧嘧啶所致高血糖大鼠血糖有明显降低作用，（高血糖模型组３６．８２，中剂量组２８．４５，高剂量组２９．２０ｍｍｏｌ／Ｌ），并改善由四氧嘧啶所引起的高血糖大鼠的糖耐量。（灌胃葡萄糖后２小时，高血糖模型组３３．８９，中剂量组３１．７７，高剂量组３０．３４ｍｍｏｌ／Ｌ）。人体试食试验是３０例Ⅱ型糖尿病人食用复合乳粉（４０ｇ／ｄ），一月后，空腹血糖平均下降（１．４５±１．１７）ｍｍｏｌ／Ｌ，餐后２小时血糖下降（２．３４±２．８５）ｍｍｏｌ／Ｌ，其中显效４例占１３．３％，有效１６例占５３．３％，无效１０例，总有效率达６３．３％，而３０例服用鲜牛奶（２５０ｇ／ｄ）的对照组的空腹血糖平均下降（０．３９±０．７８）ｍｍｏｌ／Ｌ，餐后２小时血糖下降（１．０９±０．７）ｍｍｏｌ／Ｌ，显效为０例，有效７例，总有效率达２３．３％，无效２３例。实验组与对照组能量摄入分别为（７．０１±１．９６）及? Compound hypoglycemic milk powder (hereinafter referred to as composite milk powder) is based on skim milk powder as matrix, strengthening γ-linolenic acid and zinc Zn  4mg%), chromium (Cr3 +) and so on. Animal Experimental Results: Compound milk powder has no effect on blood glucose in normal rats. At the 5th week after gavage, the medium and high dose compound milk powder group (doses of 6.67g / kg bw and 13.33g / kg bw) significantly reduced the blood glucose of alloxan-induced hyperglycemic rats (hyperglycemia model Group 36.82, medium dose group 28.45, high dose group 29.20mmol / L), and improve alloxan induced hyperglycemic rats glucose tolerance. (2 hours after intragastric administration of glucose, 33.89 cases of hyperglycemia model group, 31.77 cases of middle dose group and 30.34mmol / L of high dose group). The trial of human diet consisted of 30 cases of Type II diabetics with compound milk powder (40g / d). After one month, the average fasting blood glucose (1.45 ± 1.17) mmol / L and blood glucose .34 ± 2.85) mmol / L, of which, 4 cases were markedly effective, 13.3% effective, 16 cases were effective, 53.3% were ineffective and 10 cases were ineffective. The total effective rate was 63.3% 250g / d), the average fasting blood glucose (0.39 ± 0.78) mmol / L in the control group and 1.09 ± 0.7 mmol / L 2 hours after the meal decreased significantly 7 cases, the total effective rate was 23.3%, 23 cases were ineffective. The energy intake of experimental group and control group were (7.01 ± 1.96) and
