Breakfast accounts for about 30% of the total heat energy of the whole day, lunch 40% and dinner 30%. In the proportion of breakfast energy sources, carbohydrates should account for 55%-65% of the total energy, fat should account for 20%-30%, and protein should account for 1 1%- 15%.
Breakfast should consider everyone's appetite and taste, preferably hot porridge, hot oatmeal, hot milk and hot soybean milk, avoid drinking iced coffee, iced tea and iced milk, and eat less fried food.
In addition, acidic and alkaline foods can not be ignored. Many people are used to eating steamed bread, fried food and soybean milk for breakfast. Some people eat eggs, meat and milk. Although these foods are rich in carbohydrates, protein and fat, they are all acidic foods. If there is too much acidic food in the diet, it will easily lead to blood acidification, causing physiological acid-base imbalance in the body, and calcium deficiency will often occur. Therefore, if you can eat some vegetables and fruits containing alkaline substances, you can achieve the balance of dietary acid, alkali and nutrients.
