What is Food Sensitivity?

Food sensitivity refers to your body's delayed immune reactions to foods that trigger IgG antibodies. In a food sensitivity reaction, the IgG antibodies attach themselves to the food antigen and create an antibody-antigen complex. These complexes are normally removed by special cells called macrophages.  However, if theses complexes are present in large quantity and the offending food is still being consumed, then macrophages can’t remove them quickly enough.  The food antigen-antibody complexes accumulate and are deposited in various body tissues. These complexes release inflammation causing chemicals, which may play a role in numerous diseases and conditions such as migraines, fatigue, weight gain, irritable bowels and more.  


Why Test for IgG Food Sensitivity?

There is good evidence to support the health benefits of eliminating IgG reactive foods from your diet. IgG food sensitivities can be a contributing cause of migraine headaches, irritable bowel syndrome, bloating, indigestion, eczema, ADD, fatigue and inability to lose weight.  Because IgG food reactions are delayed reactions (taking hours or days to develop) this makes it difficult to determine which food is responsible for the reaction without doing testing.


What types of food are tested?

The standard 120 food antigen test ($375) tests for food in different food categories such as dairy, meat, vegetables, fruits and miscellaneous. The 160 food antigen test ($475) tests for only vegetarian food such as dairy, vegetables and fruits. The 200 food antigen test ($550) tests for a variety of food sources including meat and vegetarian food. You can view a complete itemized list of what is tested here
