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 low in protein. Their main source of heat is carbohydrates (including sugar and starch), especially sugar. Therefore, the same kind of fruit, sweet varieties have higher calories than non-sweet varieties.
3. When the total amount of dry goods is almost the same, the higher the fat content, the higher the calorie value. Because the calories of 1g protein and starch/sugar are 4 kilocalories, while the calories of 1g fat are 9 kilocalories, the higher the fat ratio, the higher the calorie value. For example, the energy of adzuki bean is 324 kcal/100g, that of soybean is 390, and that of raw peanut is 574. Because their fat content is 0.6%, 16% and 44% respectively.
4. The higher the digestion and absorption rate, the higher the heat. Dietary fiber in food will slow down digestion and absorption, and resistant starch is not easy to digest and absorb. However, resistant starch is often counted in the calorie value. Resistant starch is difficult to digest in the small intestine, and will directly enter the large intestine, becoming the "food" of beneficial bacteria in the large intestine and producing healthy "short-chain fatty acids". Natural whole grains, starchy beans and potatoes all contain some "resistant starch". However, after fine processing, foods with dietary fiber removed usually have higher digestion and absorption rate, such as rice steamed bread, biscuit bread and so on.
High calorie food:
1, Yuba: 457 kcal (100g)
Yuba is a traditional food that people in China like very much, and it has a strong bean flavor. However, compared with other bean products, the calorie of yuba is slightly higher, with 457 calories per 100g (82 calories for tofu, 40 calories for dried tofu/kloc-0, and 244 calories for oil tofu). When the branches and bamboos are fried with yuba, the heat is higher, reaching 472 kilocalories per100g, which exceeds the heat of pork with the same weight. Therefore, it is best for people who need to control their weight not to eat yuba often, or to reduce the intake of staple food appropriately when eating yuba.
2. Canned juice: 255 calories (one can)
Many people choose fruit juice instead of fruit, but they can't get enough minerals and vitamins, because many minerals and vitamins have been lost in the process of making fruit juice. The only remaining vitamin C will also be reduced by light. Most of the juice is concentrated back to the plateau, and a lot of sugar is added. So, if you think drinking fruit juice is more nutritious, come to a can every day. The high sugar in fruit juice will make you gain weight 12 kg after one year.
