Method for judging the calorie level of food

1, the greater the moisture content in food, the lower the calorie value. Conversely, the more dry goods, the higher the calorie value.

For example, compared with different vegetables, vegetables with high moisture content, such as wax gourd, cucumber, lettuce, etc., are "watery", and the heat is only10 ~ 20 kcal/100g. In contrast, although sweet peas and beans are also considered as high-moisture foods, there are a little more "dry goods", and the calories are 30-50 kcal/100g. The calories of potatoes and yams containing starch are even higher, reaching the level of 60-80 kcal/100g.

2. For fruits, vegetables, fruit juice, sweet drinks and other foods, the higher the carbohydrate, the higher the calorie.

This kind of food is usually low in fat (except durian and avocado), and it is also low in protein. Their main source of heat is carbohydrates (including sugar and starch), especially sugar. Sugar is a solute. The more sugar, the lower the proportion of water in fruits or drinks.
