When there is a cough it is best not to eat crayfish, because if they are not handled very cleanly, it is easier to cause acute gastroenteritis. Once severe diarrhea occurs, the body’s resistance will decline, which is not conducive to recovery from a cough. In addition, many businesses make crawfish spicy, and during a cough, spicy, stimulating food is not allowed. Therefore, it is better not to eat crayfish during coughing, and it is better to eat simple, light and easily digestible food.
