1, seafood lemon
Rumor: seafood meets lemon or other foods containing vitamin C, which is equivalent to arsenic. The reason is that soft-shell foods such as shrimp contain high concentrations of pentapotassium arsenic compounds, which react with reducing agent vitamin C and become toxic trivalent arsenic.
Clarification: The arsenic content in actual seafood is very low. The arsenic content per kilogram of seafood is not more than 0. 1 mg, and arsenic poisoning will occur only after ingesting dozens of mg. It seems that arsenic is produced by ingesting several kilograms or even dozens of kilograms of seafood at a time, which requires a lot of fruits and vegetables.
2. Crabs and persimmons
Rumor: Crabs and persimmons are cool, and the reaction after eating together will cause pain and diarrhea.
Clarification: Persimmon contains tannic acid, while crab is rich in protein. These two substances will interact. But I'm not sure if there is a reaction in the human environment. This effect will not cause diarrhea, poisoning or other obvious discomfort. Other foods rich in protein, such as fish, shrimp, meat and eggs. Similar to crabs, they are prone to spoilage, bacterial reproduction, diarrhea or allergic symptoms, but this has nothing to do with persimmons.
3. Beer and seafood
Rumor: beer and seafood will interact after eating together, leading to gout.
Clarification: The disadvantage of this combination is that there are more purines, which will increase the concentration of uric acid (metabolite of purine) in blood. But the main reason is not the reaction between them, but because they are all high purine foods. In addition, high purine foods are not only beer and seafood, but also meat and soybeans. No matter how these foods are matched, they will cause harm to gout patients or hyperuricemia patients, but they have no other harm to healthy people with normal uric acid in their blood.
