1, seafood should not be eaten with foods with high vitamin C content, especially fruits.

In recent years, due to improper treatment of industrial wastewater and improper use of pesticides, surface water and seawater have been polluted and arsenic content in water has increased. The arsenic content in some animals and plants, such as shrimp and kelp, has also increased significantly. Arsenic is divided into trivalent arsenic and pentavalent arsenic, pentavalent arsenic is basically non-toxic and trivalent arsenic is highly toxic. The well-known dramatic arsenic is trivalent arsenic. There are high concentrations of pentavalent arsenic compounds in soft crustaceans such as river shrimp or sea shrimp due to environmental pollution.

Although pentavalent arsenic is non-toxic, if it is taken together with vitamin C, especially high-dose vitamin C, it can reduce pentavalent arsenic in shrimp to trivalent arsenic due to its reduction, which is seriously harmful to human health. Therefore, friends who need to take large doses of vitamin C due to illness should draw a clear line with shrimp food. In order to prevent accidents, even friends who take small doses of vitamin C should keep a distance from shrimp temporarily, otherwise chronic arsenic poisoning may occur for a long time, and symptoms such as fatigue, numbness, dermatitis, anemia and renal insufficiency may occur.

2. Seafood cannot be eaten with beer at the same time, which may cause gout. ?

Seafood contains purine and monophosphate, while beer is rich in vitamin B 1, which is an important catalyst for decomposing these two components. Drinking beer while eating seafood can easily lead to a sharp increase in blood uric acid level, induce gout, and lead to gouty nephropathy and gouty arthritis.

3. you can't eat a lot of vitamin c at the same time when eating shrimp and crabs. Because crustacean seafood such as shrimps and crabs contain high concentrations of pentavalent arsenic compounds, which are harmless to human body, but if a large amount of vitamin C is taken at the same time, pentavalent arsenic will be reduced to trivalent arsenic, namely arsenic trioxide, commonly known as arsenic, which will lead to acute arsenic poisoning and even life-threatening in severe cases.

Don't mix seafood with fruit. Because seafood contains high protein, calcium, phosphorus and other nutrients, if it is eaten together with foods with high tannic acid content, it will not only reduce the nutritional components of seafood, but also combine calcium in seafood with tannic acid to form a indigestible substance, which will lead to vomiting, dizziness, nausea, abdominal pain and other symptoms. Therefore, fruits with more tannic acid such as tea, persimmon, grape, pomegranate and hawthorn should not be eaten with seafood at least two hours apart.
