In fact, their calories are similar, steamed bread is a little higher, but eating steamed bread is easier to get fat than eating rice, mainly because the structure of flour is simpler and easier to be digested than rice. Digestion here is the process of transforming polysaccharides into monosaccharides. After food is digested, it will enter our blood in the form of glucose, which will raise our blood sugar. When we don't exercise enough, sugar will exist in the form of fat, and we will get fat. So if you are a heavy manual worker, eating steamed bread is better than eating rice, because steamed bread has high digestion efficiency and can make you feel energetic immediately (sugar is the main way to do muscle work), but now we generally don't do that kind of work, so eating rice is also a good choice, and we must control the amount. If we eat too much, we will get fat.
