Second, allergic patients should pay attention to the balance of diet and nutrition, and eat less greasy, sweet and irritating food, cigarettes and alcohol. Some foods are also allergens, so we should pay attention to distinguish them. Eating more foods rich in vitamins can enhance the body's immune ability. According to nutritionists, onions and garlic contain anti-inflammatory compounds, which can prevent the onset of allergies. Other vegetables and fruits can also resist allergies, among which broccoli and citrus are particularly effective. People with allergic constitution had better drink some soybean milk every day.
Thirdly, desensitization therapy can be used to help some patients with severe symptoms to change their allergic constitution. In this treatment, the doctor will chemically change the patient's serum to dilute it. Inject the changed allergen and antigen immersion liquid made of milk, pollen and other substances under the skin, and gradually increase the concentration of allergen to adjust the human immune system, so that the allergic person can produce resistance to allergic substances, thus effectively preventing allergies.
