In midsummer, many people from Henan travel to Qingdao, Rizhao, and Lianyungang to see the sea. Enjoying the sea breeze, eating seafood, and relaxing must be very pleasant. However, it is important to remember not to eat fruit immediately after seafood to avoid food poisoning.
Both seafood and fruit are considered "cooling" foods. Eating a large amount of seafood can easily cause diarrhea.
Additionally, seafood like fish, shrimp, and crab are rich in nutrients such as protein and calcium. When consumed together with fruits containing tannic acid, such as grapes, pomegranates, hawthorn, or persimmons, it not only reduces the nutritional value of the protein but also tends to cause the calcium in the seafood to bind with the tannic acid, forming a new substance that is difficult to digest. This substance irritates the stomach and intestines, leading to discomfort in the body. In mild cases, symptoms like vomiting, dizziness, nausea, abdominal pain, and diarrhea may occur, while in severe cases, it can lead to gastrointestinal bleeding.
It is best to wait for an hour before eating fruit. If you experience gastrointestinal discomfort, you can detoxify by drinking a soup made from a handful of mung beans. The mung beans should be boiled for only 5 minutes; there is no need to cook them until they are soft, as long as the soup turns green. Then, drink the soup.
