The presence of proteins in certain foods is responsible for the allergic reaction after intake of even very small quantities. Some of the common food items that lead to allergies are soy, peanuts, walnuts, pecans, fish, shellfish, milk, eggs etc. Allergic response may be in the form of red, itchy rashes or patches on the skin, stuffy, running nose, teary eyes, swelling of tongue, throat irritation, vomiting, stomach spasm or loose motions.
A grave allergic reaction is termed as anaphylaxis, which is an acute response to allergens. You need to consult a physician immediately if after consuming some food you feel croakiness, tension or a swelling in the throat, puffed, chest stiffness or difficulty in breathing, tickly effect in hands, feet, lips or any other part of the body. To check your allergic affinity for certain doubtful foods you can fix an appointment with an allergic or immunologist. They perform some immediate tests to find out what you may be allergic to. In case, you are allergic to a specific food best prevention is to avoid.
The food items as well as food products containing the allergic proteins should be avoided. You should always check the ingredient labels on food products. Food allergy should not be confused with food intolerance. Food allergy is due to the immune system reaction to particular foods. Even when dining out check with the restaurant for ingredient information. Food proteins causing allergies are known by different names.
There are many milk proteins such as casein, caseinates, rennet casein, Lactoglobulin, lactulose, lactalbumin, lactalbumin phosphate etc. Egg proteins are albumin or albumen, meringue or meringue powders etc. are the items containing egg protein. Artificial flavors, marshmallows, nougat, pasta, lecithin, macaroni, marzipan lao etc. contain egg proteins.
