Allergies - Food

Unless your immune system has been compromised, the body fights back very effectively when a substance the body identifies as "foreign" enters.

These foreign substances are called antigens. When the body detects one, the immune system manufactures specific antibodies that attach to and neutralize the antigen; however, for those with allergies, a normally harmless substance such as grass pollen, peanuts, or wasp venom can cause an immune response that results in what we know as allergy symptoms.

Food allergies may start during infancy. Parents who have food allergies, or other type of allergies probably pass these traits on to their children. Occasionally, food allergies go away without any type of treatment by the time the child is 10 years old; however, other allergies seem to then occur.

Yearly flu shots are recommended for seniors (paid for by US Medicare), healthcare workers, and people with chronic lung diseases. However, there are those for whom it is not recommended: people who have a severe allergy to chicken eggs or who have had a severe reaction to a flu shot in the past; children less than 6 months old; people who have a moderate or severe illness with a fever. (They should wait until their symptoms lessen before they get the flu shot.)

Because there are no cures for allergies, it is important to know the most common triggers for allergies caused by indoor and outdoor air, triggers for allergies involving the eyes and skin, for food and drug allergies, for insect, and latex allergies.

Editor's Note:

"Race" is sometimes mentioned as a risk factor in the development of certain cancers and a number of other diseases. When you read this in a discussion about an illness, note that the explanation seldom refers to anything biological. Instead, it usually refers to behavior, such as eating habits. The kinds of behavior usually mentioned as risk factors are culturally determined. They are not genetic or biological.
