Sushi is not recommended for people with stomach problems. Because sushi is mostly made of rice or japonica rice, and it is cold, which is not conducive to digestion and has a heavy burden on the stomach. When eating sushi, vinegar and mustard are spicy and stimulating foods. People with a bad stomach suggest eating some warm food, eat less and eat more meals, and remember to eat cold, greasy and spicy food.

Sushi itself is made of cold rice. Eating cold food in winter is easy to cause gastrointestinal discomfort even for healthy people, but it is not absolute. People in Japan and Korea eat it every day, and it's nothing. The key is to have a little hot soup.
