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.
Metals tend to accumulate on the heads of seafood. Try not to eat shrimp heads and fish heads.
So; To be prudent, shrimp should be avoided during taking vitamin C.
Not only that, don't eat fruit before and after eating seafood.
Shrimp should not be eaten with some fruits. Shrimp is rich in nutrients such as protein and calcium. If you eat with fruits containing tannic acid such as grapes, pomegranate, hawthorn and persimmon, not only will the nutritional value of protein decrease, but tannic acid will combine with calcium ions to form insoluble conjugates, which will stimulate the gastrointestinal tract and cause discomfort, vomiting, dizziness, nausea, abdominal pain and diarrhea. Seafood should be eaten with these fruits at least 2 hours apart.
