After eating crabs, it is recommended to wait for a while before eating other fruits, including peaches. This is because crabs belong to seafood, and some people are allergic to seafood or easily cause indigestion. It is safe to eat peaches after 1-2 hours unless you are allergic to crabs or have digestive system problems. Personal physique is also a factor to consider. Some people have weak ability to digest and absorb certain foods, which is easy to cause gastrointestinal discomfort. If you are a person with sensitive digestive system, it is recommended to wait longer after eating crabs to ensure that the digestive system is fully recovered before eating peaches or other foods.
