What role does IgG play in Blutzucker?

The role of IgG in blood sugar regulation is often misunderstood. IgG antibodies are part of the adaptive immune system and are produced upon repeated exposure to certain foods. They are not directly involved in acute blood sugar control – that is primarily managed by insulin, glucagon, and other hormones. Some commercial IgG food sensitivity tests claim that type-III allergies can cause chronic inflammation, thereby impairing insulin sensitivity. However, the scientific evidence for this is weak: IgG levels often merely reflect food intake and do not reliably correlate with symptoms or metabolic outcomes. Current guidelines (e.g., from the German Society for Allergology) advise against using IgG tests to diagnose food intolerances. An indirect link via gut health and inflammatory markers is plausible but not well-proven. For optimizing blood sugar, focus on established factors like glycemic load, fiber, exercise, and sleep – not IgG values. The evidence here is best classified as 'marketing' or 'unclear', as claims exceed the scientific consensus.
