Advice on Becoming Familiar with What Causes Food Allergies

It's hard to pinpoint exactly what causes allergies, especially if you have a delayed allergic response.

Typically people who have an immediate reaction can pinpoint their allergy down to one or two foods. However, those who experience delayed allergic reactions may be allergic to as many as 14 or 16 different foods. To learn how to track your diet and target the cause of your allergies, keep reading.

Understanding the Allergic Response

A food allergy is actually an immune system function. Basically, the body senses a substance that it doesn't like or want inside the body. It responds by releasing white blood cells along with histamine and leukotrienes, which cause inflammation. That inflammation can occur in the stomach, intestinal tract, throat, mouth or in the form of a rash.

In addition to sending out white blood cells, the immune system also powers up its antibodies. These try to rid the body of any traces of the offending food in the intestinal tract, blood or stomach. Unfortunately, they can cause long-term harm.

With immediate-onset allergies, symptoms will appear within one to two hours of eating even a small amount of culprit food. They often manifest as hives, hay fever, asthma or swelling of the mouth, lips or respiratory tract.

With delayed allergic reactions, you may not see symptoms for as many as 3 days. Typically, delayed reactions are caused by a large amount of the culprit food.

Finding Out the Diet Resulting in Your Allergies

Keep Track of Everything You Eat

The best way to monitor your consumption and track down an allergy is to keep a food diary. By monitoring everything you eat and tracking your symptoms, you will start to see a pattern, eventually allowing you to pinpoint certain trigger items you eat.

Eliminate Culprit Foods

If you suspect a certain food is causing your allergies, don't eat it for three weeks, and then reintroduce it to see if it causes problems. If it does, you've pinpointed your allergy.

If you believe your allergy may be caused by multiple culprit foods, try eliminating all the suspect items from your diet for three weeks. After this cleansing period, begin to eat a little of each individual food, one-by-one. Allow for a four-day window between introductions. During this period, keep a careful eye on your symptoms.

Also, be aware that when you give up a food to which you are allergic, you may experience temporary withdrawal symptoms, such as headaches, fatigue, and irritability. This is normal and should not be cause for concern.

Eliminate the Culprit Food

Once you identify your culprit foods, you can omit them from your diet altogether, in which case all your symptoms should disappear within three to six months. Or, if you are not severely allergic, see whether you can eat a small amount once every four days or more without trouble. You may need to exclude the culprit foods completely for six months before you gradually reintroduce them in this way.

By understanding your allergies, the types you have and seeing the relationship between then and what you eat, you can find out which afflict you and gain relief.
