Usually, seafood and fruit together are not harmful, so shrimp and grapes can be eaten together in moderation. However, if there is an allergy to seafood itself, it is recommended to eat less or not to eat seafood. Some people believe that due to the contamination of seawater, shrimp contains a certain amount of pentavalent arsenic, which reacts with vitamin C in fruits to produce toxic trivalent arsenic and can lead to food poisoning, so they may think that shrimp and grapes cannot be eaten together, but the actual probability of such poisoning is relatively small, which is a misunderstanding. Some people have gastrointestinal discomfort reactions after eating shrimp and grapes, such as nausea and vomiting, which may be due to shrimp not being fully cooked, or improper cooking methods, or excessive consumption, or grapes not being fully cleaned and unclean diet. Therefore, if there is no seafood allergy, ensure that the shrimp is cooked and the grapes are cleaned, you can consume them together in moderation.
