What role does IgG Unverträglichkeitstest play in longevity?

The IgG food intolerance test is marketed as a tool to identify food sensitivities, but it lacks validation in mainstream medical science. IgG antibodies to foods are a normal immune response and often indicate tolerance, not intolerance. Regarding longevity, some proponents suggest that avoiding IgG-positive foods could reduce chronic inflammation and thereby slow aging. However, no robust clinical studies demonstrate a causal link between IgG test results and extended lifespan. While chronic inflammation is a known risk factor for age-related diseases, the IgG test is not a validated method to detect or manage it. The evidence is weak and largely based on marketing claims. Consumers should be aware that the test may lead to unnecessary dietary restrictions and potential nutrient deficiencies. For evidence-based longevity, established interventions such as a balanced diet, regular exercise, and stress management are more reliable.
