How are IgG and blood sugar related?

The relationship between IgG food sensitivity tests and blood sugar is not supported by strong evidence. IgG tests measure immune responses to foods, not glycemic impact. While some practitioners suggest that food-induced inflammation could impair insulin sensitivity, this link remains hypothetical and unproven in rigorous clinical trials. Blood sugar regulation is primarily governed by carbohydrate intake, insulin secretion, and physical activity – not by IgG antibody levels. Using IgG tests to guide dietary choices for blood sugar control is not recommended by major diabetes or allergy organizations. If you have concerns about blood sugar, focus on validated approaches: monitor glycemic index/load, maintain a balanced diet, and consult a healthcare provider for proper testing (e.g., HbA1c, oral glucose tolerance). Relying on IgG tests may lead to unnecessary dietary restrictions without measurable benefit. Evidence grade: marketing/unclear. Safety note: do not replace standard diabetes management with unvalidated food sensitivity tests.
