Schilddrüsen-TSH Wert Selbsttest: which diet helps?

A TSH self-test measures thyroid-stimulating hormone in the blood and can indicate potential thyroid dysfunction. However, a single reading without clinical context is insufficient for diagnosis. Diet can support thyroid function but cannot correct all TSH abnormalities. Key nutrients include adequate iodine (e.g., iodized salt, seafood), selenium (Brazil nuts, tuna), and zinc (meat, legumes). For Hashimoto's thyroiditis (common cause of elevated TSH), some evidence suggests a gluten-free or anti-inflammatory diet may help, but the evidence is limited. For low TSH (e.g., Graves' disease), ensuring sufficient calorie and nutrient intake is important. Caveat: Self-tests are screening tools, not diagnostic. Results must be reviewed by an endocrinologist. The evidence for dietary effects on TSH is mostly mechanistic or observational; large randomized trials are lacking.
