Foods rich in vitamins can enhance the body's immune function. Eat more foods with anti-allergic function to enhance the skin's defense function. According to nutritionists, onions and garlic are spicy foods containing anti-inflammatory compounds, which can prevent allergies. Other vegetables and fruits can also resist allergies, among which broccoli (cabbage) and citrus are particularly effective. Because it is rich in vitamin C, which is a natural antihistamine, if you take 1000 mg from your diet every day, it will be enough to avoid allergies. People with allergies have less free amino acids in their blood than healthy people. If the free amino acids in their blood can be increased, the incidence of allergies will be greatly reduced. The content of this substance in soybean milk is the richest, and people with allergies had better drink some soybean milk every day.

Several foods that can prevent pollen allergy

Honey: American immunologists believe that honey is very effective for pollen allergy. If you insist on drinking a spoonful of honey every day for two years in a row, you can safely spend the spring and summer when pollen allergy is high. Experts speculate that there may be two therapeutic mechanisms. First, the trace amount of bee venom contained in honey works, which is one of the "natural drugs" used by doctors to treat allergic diseases such as bronchial asthma; Secondly, because honey contains certain pollen grains, people will have certain resistance to pollen allergy after getting used to it, which is the same as the principle of desensitization therapy. As for the drinking method of honey, experts suggest that it is best not to heat it at high temperature, and it is best not to drink honey-allergic babies and babies under 1 year old.

Jujube: Japanese scholars found that jujube contains a lot of anti-allergic substance cyclic adenosine monophosphate, so it is suggested that allergic people eat more jujube, boiled or raw, one capsule per 10/0, three times a day. Stewed with 50 grams of auricularia auricula and 30 pieces of jujube, it has the effect of treating allergic purple spots. However, jujube should not be eaten with carrots and cucumbers, otherwise it will destroy vitamin C. In addition, jujube is not suitable for patients with high sugar content, damp heat, tooth decay, frequent toothache and constipation.

Flammulina velutipes: Singaporean researchers found that the stems of Flammulina velutipes contain a kind of protein, which can inhibit allergic diseases such as asthma, rhinitis and eczema. Even if you are not sick, you can eat Flammulina velutipes to strengthen your immune system. Researchers hope that in the future, protein in Flammulina velutipes can be made into drops or masks, which can be stuck (or dripped) in the nostrils to treat allergies. Experts also said that if Flammulina velutipes is only eaten as general food, protein in it may be destroyed by gastric acid after digestion in gastrointestinal tract. It is not known whether the human body can absorb it.

Carrots: Japanese experts have found that beta carotene in carrots can regulate the intracellular balance and effectively prevent allergic reactions such as pollen allergy and allergic dermatitis.
