Have you noticed that more and more people around you are getting allergies? Cases of itchy nose, itchy skin, shortness of breath, etc. seem to be increasing. Where does the problem lie? Diet is one of the most important factors in causing allergies. How can you deal with food allergies? Common symptoms of food allergy Common symptoms of food allergy are as follows: rhinitis, shortness of breath, coughing in the respiratory system; itchy or red eyes; rash, eczema, angioedema, redness, itching in the skin; abdominal pain, nausea, vomiting, diarrhea, bleeding in the digestive tract, itching in the oropharynx and other discomforts may occur in the digestive system. Causes of food allergies Allergies are caused by the body’s immune system overreacting to foreign allergens, resulting in many uncomfortable symptoms. In order to confirm which substance is causing the allergy, detailed tests must be conducted to find the antibodies and other related substances produced by the immune system in response to the substance in order to be identified. Currently, blood analysis can be used to identify allergies, but not all allergens can be found. Another type of food allergy is not related to the immune system, for example, some people will have skin allergies when eating strawberries, chocolate, or shellfish; others will be sensitive to MSG; and others will have migraines caused by food. This may be caused by the body’s inability to adapt to the specific ingredients of certain foods or to metabolize and eliminate them. For people with asthma problems, they can also be induced by cold temperatures after eating cold food or perhaps even just drinking ice water. In fact, because each person’s body type is different, the causes of allergies are also different. Allergies are also related to genetics. If the parents are allergic, the children will have a higher chance of developing allergies. Foods that may cause allergies Generally speaking, milk, soy, peanuts, eggs and fish are commonly mentioned in pediatrics as foods that may cause allergies in infants and children after consumption. Foods that cause allergies in adults commonly include fish, drupes, peanuts, crustacean seafood (such as shrimp and crab), and flour. With the modern food industry, there are also some people who are allergic due to food additives, such as colors, antioxidants, and preservatives. Such foods containing additives, such as preserves, golden needles and some candies, should be eaten sparingly by allergy sufferers to avoid triggering asthma. A frequently mentioned allergy food is none other than seafood. For many people, however, it is the “lack of freshness” in seafood that causes the discomfort caused by the excess histamine it contains. Only a few people are born with a lack of enzymes to break down histamine, so eating fish, even freshly caught fish, can cause allergies due to the small amount of histamine. In addition, some foods do not necessarily have to be consumed, even if only contact, may cause itchy, red and swollen skin allergic reactions, such as bananas, avocados, kiwi, chestnuts, papaya, pineapples, peaches, figs, potatoes, cherries, grapes, celery, tomatoes, carrots, wheat, hazel beans, and even apples and pears have been recorded! Allergy avoidance diet principles ① Avoid foods that cause allergies This is the simplest and most effective way. If you suspect that a certain food is causing allergies, it is best to try it once or twice after the allergy occurs to confirm the culprit of the allergy and to avoid the problem of partial eating or nutritional imbalance. ②Take enough vitamins Italian researchers have found that eating more fruits containing vitamin C can help relieve the symptoms of asthmatic children. There are other reports that people with vitamin C deficiency are particularly prone to allergies. This may be because vitamin C can help the integrity of the body’s tissues, making it less likely that allergens will invade the body and trigger allergies. To reduce allergy symptoms, people suffering from allergic rhinitis, asthma and other diseases should first control the amount of oil they use on a regular basis, eat less fried food, avoid using sunflower oil or corn oil, and choose canola oil, soybean oil, etc. They should also moderately increase the intake of fish such as salmon, mackerel, herring, swordfish and walnuts.
