老年人由于能量的需要减低,食物摄入量可稍少。第一,最好将主要必需的营养分为四类:①肉、鱼、家禽、豆类,②牛奶及奶制品,③蔬菜、水果,④谷类。一般由前二组中选二种,后二组中选四种即可供给必要营养的80～120%,同时保持能量的摄入;第二,不要饮酒及摄入纯脂肪和碳水化合物。不要接受一些关于营养方面的错误传说,过量地专吃某种食物或不吃某种食物,以免导致膳食的不平衡,甚至营养低下。水果、蔬菜、粮食中摄入的中等量的纤维,对老年人很理想,既可减少便秘,又可改善肠肌的强度
Elderly due to the need to reduce energy, food intake may be less. First, it is best to classify the most essential nutrients into four categories: ① meat, fish, poultry, beans, ② milk and dairy products, ③ vegetables, fruits and ④ cereals. Generally, two groups are selected from the first two groups, and four from the latter two groups can supply 80 to 120% of the necessary nutrients while maintaining energy intake. Second, do not drink alcohol or consume pure fats and carbohydrates. Do not accept some erroneous rumors about nutrition, over-eating a particular kind of food or not eating certain foods, so as not to lead to imbalances in the diet, or even low nutrition. The moderate amount of fiber in fruits, vegetables and grains is ideal for the elderly, which can reduce constipation and improve the strength of intestinal muscles
