Food Detective - FAQs: Food IgG Antibody Testing

Is it possible to be affected by foods that are not detected by IgG antibody tests?

Some foods may cause a classical allergic reaction involving the production of a type of antibody called IgE. These will not be detected by any IgG food test. There are also many foods that can cause a reaction in the body without involving the immune system but produce symptoms similar to IgG reactions. For example, amines in chocolate, cheese and red wine may cause migraines; some food additives such as tartrazine can cause hives, rashes and asthma; monosodium glutamate in Chinese dishes produces sweating and dizziness; and ‘Nightshade’ alkaloids in potatoes, tomatoes and peppers can affect the joints. These are very difficult to test, but you should avoid them if you suspect they are affecting you.
