You can eat millet soup, lotus root powder and thin noodles with acute gastroenteritis. You can drink more warm water to avoid dehydration and eat a diet that is easily absorbed and does not increase the burden on the stomach and intestines. Millet soup is made from millet and adds a lot of water to boil out the nutrients in the millet. Drinking millet soup can replenish the body’s energy without causing irritation to the intestinal system and help recovery. Lotus root powder is a high-calorie food that has the effect of strengthening the spleen and appetite. Lotus root powder is rich in water and does not produce food residues when digested in the intestine, making it a suitable food to eat during an acute gastroenteritis attack. Noodles are made from starch, which can supplement the body’s nutrition. Since they are rotten, they do not burden the stomach and intestines, and are suitable for consumption after acute gastroenteritis has subsided.
