The effect of four menstrual cycle phases on changes in dietary intake, urinary nitrogen excretion, and urinary volume was examined in nine women confined to a metabolic unit, maintained at a constant activity level, and fed an ad libitum, rotating, staff-weighed diet. No significant changes in intakes of energy, protein, and fat occurred throughout the menstrual cycle although significant changes were found for intakes of ascorbic acid and water in food. A significant increase in consumption of carbonated, sugar-containing beverages was found in the luteal phase as was a significant increase in urine volume. Results suggest food choices and urine volume may be responsive to physiological regulators associated with hormonal changes in the menstrual cycle. Findings also suggest that energy intake is not altered across the menstrual cycle when physical activity is controlled and an accurate dietary assessment method is employed.
在9名被限制在代谢单元、保持恒定活动水平并随意食用由工作人员称重的轮换饮食的女性中，研究了四个月经周期阶段对饮食摄入量、尿氮排泄量和尿量变化的影响。在整个月经周期中，能量、蛋白质和脂肪的摄入量没有显著变化，尽管食物中抗坏血酸和水的摄入量有显著变化。在黄体期，含碳酸和糖的饮料的消费量显著增加，尿量也显著增加。结果表明，食物选择和尿量可能对与月经周期激素变化相关的生理调节因子有反应。研究结果还表明，当身体活动得到控制且采用准确的饮食评估方法时，整个月经周期的能量摄入量不会改变。
