摘　　要：目的探讨分别饮用牛奶和豆浆对健康男性大学生血浆中钙、磷、胰岛素、葡萄糖、雌二醇和睾酮水平的影响。方法将36名大学生随机分为牛奶组、豆浆组,矿泉水组,每组12人,连续3周每天饮用指定样品1000mL,测定干预前后血浆中相关生化指标的变化。结果干预前3组间指标无明显差异;干预后牛奶组和豆浆组血钙水平分别上升了0.19和0.20mmol/L(P<0.005);豆浆组血磷水平(1.34±0.17)mmol/L明显高于矿泉水组(1.17±0.20)mmol/L(P<0.05);牛奶组血浆雌二醇水平(37.92±10.98)pg/mL明显高于矿泉水组(30.42±9.22)pg/mL(P<0.05);3组之间血浆胰岛素和血糖无明显差异。结论饮用牛奶后血钙水平在正常范围内有所上升;饮用豆浆后血钙、血磷均在正常范围内有所上升;饮用牛奶提高了雌二醇水平。Objective To study the effects of milk and soy milk intake on plasma calcium,phosphorus,insulin,glucose,estradinl,and testosterone in healthy young men.Methods Thiryt-six male undergreduate students were randomly assigned to milk group,soy milk group and water group for a 3 weeks dietory intervention.The plasma levels of biochemical indicator were determined before and after the inrvention.Results Plasma calcium increased by 0.19 mmol/L（P 0.05） and 0.20 mmol/L（P 0.05） after the intervention with milk and soy milk,respectively.After intervention,plasma phosphorus level was significantly higher in the soy milk group（1.34 ± 0 17 mmol/L） than that of in the control group（1.17 ±0.20 mmol/L,P 0.05）.The plasma estradiol level was significantly higher in the milk group（37.92 ±10.98 pg/mL） than that of in the control group（30.42 ±9.22 pg/ml,P 0.05）.The intervention did not significantly change plasma insulin and blood glucose（P 0.05）.Conclusion The results suggest that the effects of heavy consumption of milk and soy milk on health should be further investigated.
