Living With A Food Allergy

Food allergies effect such a large number of people that it seems most people know at least someone with a food allergy. These allergies can be difficult to live with and even worse they send thousands of people to the emergency room each year; they are also the cause of a few deaths each year.
Many people suffer from a food intolerance, which shouldn’t be confused with a food allergy. They are two distinct and different conditions that result in different consequences.
Many people have an intolerance of certain foods or additives, but this is very different than having a food allergy. An allergy can show within minutes of eating the trigger food, while an intolerance will result in a belated reaction to the food. An allergy is an immune response while an intolerance is more related to improper digestion.
A food allergy is the body’s reaction to a substance that it views as possibly harmful. The immune system works to constantly protect our bodies from these things it deems harmful. The allergen is seen by the body as one of these substances so the immune system goes to work trying to protect the body by releasing protective chemicals. One of the chemicals released is histamine, which can affect the nose, eyes, throat, skin or GI tract.
How do you know if you’re having an allergic reaction? Some of the signs are a tingly feeling in or around the mouth, swelling of the tongue, throat or lips, nausea, vomiting, diarrhea, hives or shortness of breath. In more serious cases the reaction can lead to anaphylactic shock which involves several systems in the body and can even lead to death.
Food allergies seem to be more prevalent every day but the majority of allergies are caused by just eight foods — eggs, milk, peanuts, tree nuts, seafood, shellfish, wheat and soy. In the United States these eight are responsible for over ninety percent of food allergies. While allergens may vary to some degree from country to country these eight are generally the most common.
The best treatment for allergies is to avoid the allergen. This may sound simple enough with a food allergy (vs and airborne allergy), but unfortunately it isn’t always that easy. Often times these allergens may be hidden in processed foods. To help with this the U.S. requires that food labels list the eight common allergens.
The labeling has been a big help, but unfortunately it doesn’t assure the food is completely free of allergens. They can also slip into the food system through cross-contamination. This can be a problem when a plant products multiple foods, some of which contain common allergens. The machines are cleaned before processing a new food, but traces of the allergen can remain and be passed to the next food that’s processed.
Luckily most labels now have an allergy section where they list what other types of foods are processed in the same facility, but there are other things food allergy sufferers will need to look for as well. Ingredients that contain allergens can be listed under different names, for example casein and whey are forms of milk protein. Those with a dairy allergy will need to avoid these ingredients.
People with allergies will need to be familiar with the signs of a possible allergy reaction. They will also need to know how to treat themselves to prevent or reduce the chances of anaphylactic shock. Treatment usually involves the use of an epinephrine injector, often called an EpiPen.
