进餐时饮果汁有学问果汁不能代替水果,人们一般早餐很少吃蔬菜和水果,所以早晨喝一杯新鲜的果汁或纯果汁应该是一个好习惯,补充身体需要的水分和营养。可惜的是人们常常喝一杯牛奶,就无法再喝下别的了。要注意的是,空腹时不要喝酸度较高的果汁,先吃一些主食再喝,以免胃不舒服。 Drinking fruit juices at mealtime is not a substitute for fruits. People generally eat vegetables and fruits for breakfast, so having a glass of fresh fruit juice or pure fruit juice in the morning should be a good habit to replenish the body’s water and nutrients. Unfortunately, people often drink a glass of milk, they can no longer drink anything else. It should be noted that, fasting do not drink high acidity juice, eat some staple food before drinking, so as not to stomach.
