Food allergy is a hypersensitivity to particular food ingredients. It’s relatively widespread and occupies second place after pollen allergies. Currently more than 2% of adults are sensitive to one or more certain foods. Food allergy can be either mild and cause no problems or severe and become a real trouble for an allergy sufferer. Food allergy reaction appears when a particular ingredient you’re allergic to comes to your body. Human immune system may consider some foods inimical and so it produces special chemicals to fight with them. You will notice this in the form of allergic reactions. The reaction depends on how severe your food allergy is. If you have mild to moderate food allergy, you may feel stomach upset and hives or rashes within several hours. Moderate food allergy sufferers experience allergy reaction symptoms much faster. You might feel numbing of lips and mouth within 30 minutes or an hour. Those people who have severe food allergy should be extra attentive to what they eat as even small amounts of food they’re allergic to can cause serious problems like anaphylaxis – the most dangerous food allergy form. Its symptoms include throat and tongue swelling that cause difficulty breathing. Sometimes throat swelling can stop airflow and thus, death of a patient. Overall up to 200 people die from anaphylaxis every year in the US, so if you suffer from severe food allergy and have eaten something you’re allergic to, seek medical help right away. Food allergy is almost impossible to cure. The best suggestion here is to avoid eating the product that causes allergy reactions. As we primary eat food that consists of several ingredients, check food labels. In general fish, various types of nuts, milk, eggs, soy, seafood and wheat are among most frequently food allergy causes. If your allergy is severe, you must check food labels carefully as sometimes due to manufacturing process products can be impure. For example, chocolate might have small portions of nuts. This happens because of cross-contamination. Quite often the same machines are used to produce allergen-containing and allergen-free food (chocolate with nuts and pure milk chocolate). Even though the machines are cleaned, traces of allergens still can appear on the surface and can possibly be found in products that are allergen-free. Certainly, food allergies, especially sever one, implies making some adjustments to lifestyle. You will need to be attentive to what you eat, check food labels carefully and ask waiters in restaurants whether the meals you’re going to eat is clear from allergens or no.
