Steamed bread is high, 100g steamed bread is 200 kcal, and rice 100 kcal. Every100g of raw rice contains about 330 kilocalories. This amount is basically equivalent to lean pork. However, rice will not be eaten dry, and each serving of rice needs to add more than 1.5 times of water when cooking. Therefore, after cooked rice, the heat per100g of cooked rice is reduced to about120kcal, which is only equivalent to the heat contained in one and a half apples.

In contrast, the calorie per100g of steamed bread is about 2 10 kcal, the calorie of staple sweet bread is about 280 kcal, and the calorie of biscuits is as high as 450 kcal. That is to say, in terms of starch content, the same volume of rice has higher water content, while the starch content is lower than that of steamed bread, bread and biscuits.

Digestion and absorption rate of rice and steamed bread

The raw materials of rice and steamed bread come from rice and wheat. Both of them contain phytic acid, which can promote the digestion of human body, and phytic acid will not be destroyed during the cooking of rice. However, steamed bread needs to be fermented in the production process. Some phytic acid will be further lost during fermentation.

Phytic acid in rice is directly cooked without fermentation, and there is more phytic acid, which will affect the absorption of nutrients. If you don't eat it while it is hot, it will produce resistant starch and waste some calories, which is why "cold rice is easier to lose weight".
