人常说:早餐吃好、午餐吃饱,晚餐吃少;也有这样说的:满足早餐,吃好午餐,节制晚餐。两种说法虽然有别,但其精神实质基本相同,也都说得很有道理。 对中老年人来说,晚餐不仅要吃少,而且要吃清淡。摄入的热量不得超过全天量的30%,这对防止和控制发胖大有好处。科学研究发现,人的基础代谢下午高于上午,下午迷走神经容易兴奋,兴奋的迷走神经可使胰腺分泌旺盛,各种消化酶含量增多,消化吸收能力加强。晚餐酒足饭饱,血糖和血中氨基酸、脂肪酸浓度增大,促使胰岛素大量分泌,而晚上活动又少,能量消耗低,多余的热量在胰岛素的作用下,大量合成脂肪储存在体内,因而逐渐使人发胖。俗话说:“千金难买老来瘦。”肥胖对中老年人来说,是很不好的。
People often say: eat breakfast, lunch full, eat less dinner; also said that: to meet the breakfast, eat lunch, control dinner. Although there are differences between the two versions, their spiritual essences are basically the same, and they all make sense. For the elderly, dinner not only eat less, but also to eat light. The amount of calories you consume should not exceed 30% of your daily dose, which is good for preventing and controlling fat gain. Scientific research found that people’s basal metabolism in the afternoon than in the morning, afternoon vagus nerve easy excitement, excitement of the vagus nerve can make pancreatic secretion, increased digestive enzymes, digestion and absorption strengthened. Supper full meal, blood sugar and blood amino acids, fatty acids increased concentration, prompting a large number of insulin secretion, and less activity at night, low energy consumption, excess heat in the role of insulin, a large number of synthetic fat stored in the body, and thus gradually Make people fat. As the saying goes: “It’s hard to buy old and thin.” Obesity is very bad for middle-aged and elderly people.
