Many methods are available to detect food allergies. If you have been eating a lot of a particular food, you are more likely to register sensitivity with many of these methods. Common food sensitivities include wheat (gluten), corn, dairy, soy and eggs.
Applied Kinesiology. This procedure employs testing of muscle strength to assess food sensitivities. It is a way to tune in to the body’s energy system. A food that reacts in the body will generally cause a muscle to go weak. The test is performed by having the person taste a food and then testing the muscles. Kinesiology in the hands of a skilled practitioner can be very accurate, fast and inexpensive.
Avoid and Challenge Testing. A simple and effective method is to eliminate a suspected food for a week or two and then reintroduce it. Many people will notice they do not feel as well if they reintroduce an offending food. Energy may decrease, or one may develop a runny nose, bags under the eyes, headache, upset stomach, gas or other symptoms.
Blood Tests. Among the blood tests used to detect allergies is the RAST (radioallergosorbent) test. This tests for IgE or IgG antibodies in the blood, and is fairly accurate. Another good test for food allergies is the ELISA (enzyme-linked immunosorbent assay) test, often excellent to detect hidden food allergies and sensitivities.
