Shrimp and crab foods contain a certain amount of pentavalent arsenic compounds, and watermelon contains vitamin C, which has the function of oxidation. Eating the two together may also produce toxicity and toxic reaction. Therefore, it is generally recommended not to eat watermelon immediately after eating crabs, and to eat it at least 2 to 3 hours apart, so as to effectively absorb the nutritional value of both without causing toxic side effects.
Crabs belong to high protein foods, and watermelons are equally cold. After they are eaten together, they will react in the stomach, which will easily lead to gastrointestinal tract diseases and even food poisoning. It is suggested that watermelons should not be eaten within one hour after eating crabs.
Crabs, shrimps and watermelons are cool, so avoid eating watermelons after eating, otherwise it will easily lead to gastrointestinal discomfort and diarrhea symptoms.
When you have gastrointestinal problems, you should pay special attention to diet conditioning. The diet is mainly light and digestible food. Eat less sweet and sour, spicy, cold and greasy products.
