Crab and grapes cannot be eaten together. Crab is rich in protein, if eaten together with fruits containing tannic acid like persimmon, grape, pomegranate, hawthorn, green fruit, etc., it will not only reduce the nutritional value of protein, but also easy to make the protein and tannic acid combine to form a kind of solidified substance that is not suitable for digestion. This substance can irritate the mucous membranes, causing abdominal pain, nausea, vomiting and other symptoms.

How long can you eat crabs after eating grapes

You can eat crabs about 2-3 hours after eating grapes. Crabs and grapes can not be eaten at short intervals, if the interval of 2-3 hours should not be a problem, because the general food as long as the interval of more than 2 hours will not have a reaction.
