The statement that four kinds of people cannot eat oats is wrong. As long as the people who are not allergic to oats can eat oats in moderation, but people with weak digestive ability need to reduce the amount. Each 100 grams of oats contains 389 calories, of which 66.3 grams of carbohydrates, 10.6 grams of dietary fiber, 16.89 grams of protein, 6.9 grams of fat, 54 milligrams of calcium, 429 milligrams of potassium. Oats belong to the higher calorie food, while the dietary fiber content is also very high, is conducive to promote intestinal peristalsis, promote defecation, constipation patients can eat more appropriately. At the same time, oats is a high potassium food, hypertension patients can eat more in moderation. However, due to the relatively high fiber content of oats, the weak digestive ability of the population if consumed too much oats can easily lead to flatulence, stomach pain, indigestion and other symptoms, so it is necessary to properly control the amount of intake. People who are allergic to oats should not eat oats.
