晚餐与肥胖 晚餐吃得过饱,血糖、血中氨基酸及脂肪酸的浓度就会增高,从而促使胰岛素大量分泌。因为人们在晚上一般活动量较少,热能消耗很低,多余的热量在胰岛素的作用下大量合成脂肪,逐渐使人发胖。因此,中老年人晚餐宜清淡,摄入的热量不应超过全天总热量的30％,这对于防止和控制发胖有益。 Dinner and obesity dinner too full, blood sugar, blood levels of amino acids and fatty acids will increase, thus contributing to the secretion of large quantities of insulin. Because people generally less activity at night, heat consumption is very low, the excess heat in the synthesis of fat under the action of insulin, and gradually make people fat. Therefore, the elderly should be light dinner, intake of calories should not exceed 30% of total heat throughout the day, which is beneficial to prevent and control fat.
