If you suspect that you are allergic to a specific food, a simple test can help you determine if you are correct. By recording your blood pressure after consuming the food in question, you can reveal if you are having an allergic reaction. Using a watch with a second hand, sit down and relax for a few minutes. When completely relaxed, take your pulse at the wrist or neck. Count the number of beats in a sixty-second period. A normal pulse reading is 52-70 beats per minute. Consume the food that you are testing for an allergic reaction. Wait 15-20 minutes and take your pulse again. If your pulse rate increased more than ten beats per minute, omit this food from your diet for one month, and then retest.

Food allergies and food intolerances are not the same. Those with intolerance lack certain enzymes needed for digestion, and therefore do not break down the food properly. Undigested food can enter the bloodstream and cause a reaction. After repeated exposure to the food, symptoms will arise. Sometimes symptoms arise immediately upon chewing, or just a tickle in the throat or cough. Other times it is difficult to identify, as it may be a delayed reaction hours later. You might be able to tolerate the offending food once or twice a week. But as soon as you eat the food daily, intolerance can occur. An allergy occurs when a person has an antibody response to the ingested food every time.
