Myths vs facts: IgG and Stress

IgG tests are often marketed for detecting food intolerances, but scientific evidence is weak. Elevated IgG levels typically reflect normal immune exposure, not intolerance. Stress can influence immune function, but a direct causal link between IgG and stress is not established. Measuring IgG against specific foods lacks clinical validation. MyBody-X does not offer such tests in the provided context. Consumers should be cautious: these tests are not recognized medical diagnostics and may lead to unnecessary dietary restrictions. Evidence: mixed – mechanistic studies exist, but clinical validation is lacking.
