Patients with allergic purpura can eat chicken. In the diet of patients with allergic purpura, the general principle is to try to reduce the consumption of spicy foods and some potential irritants such as celery, coriander, and shiitake mushrooms, which should be eaten sparingly. Chicken is not considered an irritant and can be consumed. In addition to strict dietary precautions to avoid allergens, patients with allergic purpura should also avoid vigorous exercise and strictly avoid getting cold and infections, as both vigorous exercise and infections can potentially trigger acute episodes of allergic purpura.
