Why test IgG for food sensitivity?
There is a growing body of evidence to support the clinical benefits of eliminating IgG-reactive foods from the diet. IgG food sensitivities have been implicated in migraine headaches. Bloating and indigestion are also common food sensitivity reactions, as is fatigue. Continued consumption of reactive foods may contribute to weight gain and/or difficulty losing weight. Because IgG food reactions take hours or days to develop, this makes it difficult to determine which food is responsible for the reaction without doing testing. Several research studies suggest there are benefits to performing food elimination diets based on what foods cause an IgG food reaction.
This article discusses the beneficial implications of IgG testing. It provides information on how individuals had health improvements after an elimination of foods that tested positive for IgG reactivity.
