Abstract
- The effect of varying energy and protein intake on nitrogen balance in adult men engaged in heavy manual labour was investigated. 2. Low protein and energy levels resulted in negative N balance and urea index (Waterlow, 1963) was decreased. 3. Urinary excretion of hydroxyproline was found to be sensitive to dietary protein level, but not to energy.
摘要
- 研究了不同能量和蛋白质摄入量对从事重体力劳动成年男性氮平衡的影响。2. 低蛋白和低能量水平导致氮负平衡，且尿素指数（沃特洛，1963年）降低。3. 发现羟脯氨酸的尿排泄量对膳食蛋白质水平敏感，但对能量不敏感。
