海味中的鱼、虾蟹,均含有丰富的蛋白质和钙等营养物质。如与含鞣酸较多的水果同食,不仅会降低蛋白质的营养价值,而且易使海产品中的钙质与鞣酸结合成一种不易消化的物质,并能刺激肠胃,引起肚子疼、呕吐、恶心等症状。因此,合鞣酸较多的水果如柿子、葡萄、山楂等,不宜与海味同时食用。 Seafood fish, shrimp and crab, are rich in protein and calcium and other nutrients. As with the more tannin containing the same food, not only will reduce the nutritional value of protein, but also easy to make seafood with calcium and tannic acid into a non-digestible substances, and can stimulate the stomach, causing stomach pain, vomiting , Nausea and other symptoms. Therefore, tannin more fruits such as persimmons, grapes, hawthorn, etc., should not be consumed with seafood at the same time.
