Many studies have shown that additives such as monosodium glutamate (MSG), the sugar substitute aspartame and several food dyes do not cause allergic reactions. Studies of MSG have shown that most symptoms attributed to MSG cannot be reproduced during blinded MSG challenges. However, in some sensitive people, food additives can cause an adverse reaction. This sensitivity is almost always an example of food intolerance, rather than true allergy.

The most common foods behind allergic reactions include nuts, peanuts, milk, egg, wheat, and soy bean proteins. Some food preservatives, such as metabisulfate and monosodium glutamate (MSG), can also cause allergic reactions. See similar questions...

Nothing has been substantiated on any poisoning by Kombucha Tea. Allergic reactions are rare, however, not impossible, since Kombucha is a food. See similar questions...

Wasps, honey bees, hornets, yellow jackets and ants are the insects most likely to cause strong allergic reactions. Some biting insects (mosquitoes, flies, lice, kissing bugs and fleas) can cause allergies as well because they inject saliva to thin the blood when they bite. Finally, some caterpillars are covered with hairs that contain a substance irritating to human skin and this can sometimes cause allergic reactions. See similar questions...

The most common food allergies are to eggs, peanuts, tree nuts (such as almonds, pecans, cashews, Brazil nuts and walnuts), milk, wheat, soy, fish, and shellfish. See similar questions...

We have no idea if it will cause an allergic reaction on you or your family. As with ANY product, use a small portion on your forearm and check it every hour for eight hours before using. If you have any reaction whatsoever, you can send the entire kit back and we will refund your money for the product. See similar questions...

Dust mites themselves are not inhaled; rather, proteins found in their waste particles cause allergic reactions. These proteins, referred to as an allergens since they cause allergic reactions, can be found in dust mite feces, skin, and decomposing body fragments. Dust mite feces contain a powerful enzyme that breaks down the droppings so that remaining fecal nutrients can be eaten by dust mites if food is scarce. See similar questions...

Yes. If you have ever had hives, facial swelling, asthma (wheezing), or shock after taking a pain reliever or fever reducer, do not take ALEVE. You may have a serious reaction. See similar questions...

Anaphylaxis is a severe, potentially fatal allergic reaction. It's difficult to precisely report how many people die from anaphylaxis because the cause of death may often appear to be a heart attack. Fatal anaphylaxis normally occurs because of extreme allergic reactions to foods such as shellfish, cod, or peanuts, or to the venom of stinging insects like wasps or fire ants. Approximately 100 Americans die annually from anaphylaxis induced by stinging insects. See similar questions...

Since our latex is derived from a synthetic petroleum base versus natural latex, which uses rubber tree sap, we avoid the impurities and proteins that cause allergic reactions to latex. See similar questions...

Foods that commonly cause allergy in infants and children are egg, fish, milk, peanuts, soy, and wheat. Foods that commonly cause allergy in adults are soy, fish, shellfish, peanuts and nuts. However, food allergy may develop to any food that is included in the diet, and may develop at any time in life. See similar questions...

Allergic reactions caused by PPD containing hair dye, in mild cases usually only involves dermatitis to the upper eyelids or the rims of the ears. In more severe cases there may be marked reddening, swelling and blistering of the scalp and the face. The eyelids may close completely and allergic contact dermatitis reaction become widespread.

The most common manifestations of allergic reactions to foods may involve the skin (causing rash, hives, itching or swelling), respiratory tract (wheezing, cough, chest tightness, shortness of breath, sneezing, runny nose), cardiovascular system (dizziness, lightheadedness, loss of consciousness, chest pain) and gastro-intestinal tract (including stomach cramps, nausea, vomiting, and diarrhea). Experts do not know why some people have mild reactions and others have life threatening reactions. See similar questions...

The most serious allergic reactions to food are those that involve the respiratory or cardiovascular systems. See similar questions...

Although this theory was popularized in the 1970's, well-controlled studies conducted since then have produced no evidence that food color additives cause hyperactivity or learning disabilities in children. A Consensus Development Panel of the National Institutes of Health concluded in 1982 that there was no scientific evidence to support the claim that colorings or other food additives cause hyperactivity.

Other reactions to foods may be due to food tolerance (e.g., lactose intolerance) rather than food allergy. These reactions do not involve the immune system. See similar questions...

In general there are three kinds of reactions to insect stings. The first kind, normal reactions, involve pain, redness, swelling, itching, and warmth at the site of the sting. The second kind, toxic reactions, are the result of multiple stings. Five hundred stings within a short time are considered likely to kill because of the quantity of venom involved. As few as ten stings within a short time can cause serious illness. See similar questions...
