1. Under normal circumstances, people who are allergic, weak spleen and stomach, gout and other people need to fast. Arctic shell is rich in protein, vitamin A, calcium, iron, phosphorus, zinc and other nutrients, which can provide nutrition and energy for the body, and has the effects of nourishing yin and calming the yang, strengthening the spleen and appetizing, nourishing the liver and tonifying the kidney.

2. People with allergic constitution are forbidden to eat Arctic shellfish, because they may have allergic reactions after eating, and are prone to rash, cough and other symptoms.

3. People with weak spleen and stomach also need to fast Arctic shellfish, because Arctic shellfish is a cold food, and people with weak spleen and stomach have poor spleen and stomach function, so eating Arctic shellfish is easy to stimulate the spleen and stomach, and may cause symptoms such as diarrhea and nausea.

4. In addition, people with gout also need to fast the northern shell, because the northern shell is rich in protein, and the rich protein is metabolized in the body, which is easy to produce purine and then form uric acid, which leads to high uric acid and gout.
