目的研究补充组氨酸对代谢综合征女性宏量营养素摄入肝肾功能、及血清钙、铜、锌、磷水平的影响。方法采用临床随机对照双盲干预试验,共招募100名代谢综合征的肥胖女性,随机分为组氨酸补充组和安慰剂组,组氨酸组每天补充4g/d组氨酸,安慰剂组服用安慰剂共持续12w。干预结束计算基线和干预后受试者的膳食营养素摄入、测定肝肾功能指标及血清钙、铜、锌、磷水平。结果干预前,干预组和安慰剂组的总能量、蛋白质、脂肪和碳水化合物摄入,肝脏酶指标、血清尿素氮、尿酸、肌苷,血清钙、铜、锌、磷没有统计学差异。干预组氨酸12w后,干预组和安慰剂组的总能量、蛋白质、脂肪和碳水化合物摄入,肝脏酶指标、血清尿素氮、尿酸、肌苷,血清钙、铜、锌、磷无统计学差异。干期间两组人群无任何不良反应。结论补充组氨酸4g/d 12 w后,对代谢综合征妇女的膳食摄入、肝肾功能和血清钙、铜、锌、磷水平无影响。
Objective To investigate the effects of histidine on the intake of liver and kidney, serum calcium, copper, zinc and phosphorus in women with metabolic syndrome. Methods A randomized double-blind clinical trial was conducted. A total of 100 obese women with metabolic syndrome were enrolled and randomly divided into histidine supplementation group and placebo group. Histidine group was daily supplemented with 4g / d histidine and placebo group Taking placebo for a total of 12w. At the end of the intervention, dietary intakes of the subjects were calculated at baseline and after intervention. Liver and kidney function indexes and serum calcium, copper, zinc and phosphorus levels were measured. Results Before intervention, the total energy, protein, fat and carbohydrate intake, liver enzymes, serum urea nitrogen, uric acid, inosine, serum calcium, copper, zinc and phosphorus in intervention group and placebo group were not statistically different. After intervention with histidine for 12 weeks, total energy, protein, fat and carbohydrate intake, liver enzymes, serum urea nitrogen, uric acid, inosine, serum calcium, copper, zinc and phosphorus in the intervention group and the placebo group were not statistically difference. Two groups of people during the dry without any adverse reactions. Conclusion After 4g / d of histidine supplementation for 12 weeks, there is no effect on dietary intake, liver and kidney function, serum calcium, copper, zinc and phosphorus in women with metabolic syndrome.
