We classify foods into six categories according to their ingredients: cereals, vegetables, fruits, milk, eggs, beans, fish and oils. Know the weight, calorie, quantity and equivalent exchange table of three nutrients (protein, fat and carbohydrate) of each food.

The following is the recommended proportion of food per day, with grain accounting for the largest and oil the smallest.

When in use, you only need to allocate three nutrients according to the total calories needed for the whole day, and then refer to the exchange table and choose the appropriate food types and amounts according to your personal preferences, so that you can make a whole-day recipe.

The first step in using the food calorie conversion table is to know which food belongs to which category.
