Persimmons and tomatoes

Purple sweet potato should not be eaten with persimmon, because purple sweet potato will lead to increased gastric acid secretion, and persimmon contains more tannic acid and other substances, which will react with gastric acid to form precipitation. Mild people will feel gastrointestinal discomfort, and severe people will cause gastrointestinal bleeding and gastric ulcer. Therefore, people with gastrointestinal weakness or digestive dysfunction should avoid eating purple sweet potatoes with persimmons. Purple potato should not be eaten with tomatoes, because tomatoes contain a lot of acidic substances such as malic acid and citric acid, which easily make purple potatoes form substances that are difficult to digest and absorb in the stomach. People with weak spleen and stomach or poor digestive function and food intolerance are prone to abdominal pain, diarrhea and indigestion if they eat it.
