Eating shrimp and persimmons in normal amounts is not harmful to the human body.
The vitamin C in persimmons will convert the non-toxic pentavalent arsenic in seafood into toxic trivalent arsenic, and the main component of arsenic is trivalent arsenic. However, this is only theoretically possible and requires special experimental conditions. The amount that people normally consume is far from the level of poisoning.
So eating shrimp and persimmons on the basis of normal consumption does not require special solutions.
Extended information:
Persimmons should not be eaten on an empty stomach and should not exceed 200 grams per day. Persimmons contain a large amount of tannic acid and pectin. If eaten on an empty stomach, they may become insoluble under the stimulation of gastric acid. If the sediment is not discharged, it will remain in the stomach and form gastric persimmon stones.
In addition, those with weak gastrointestinal function, the elderly and children should eat less, and do not eat foods with high calcium and iron content immediately after eating. The total amount of fruit consumed by normal adults is about 200 grams per day. If you eat persimmons, it should not exceed 200 grams per day.
