Hashimoto's Hypothyroidism Protocol
Berg states that 90% of hypothyroidism is Hashimoto's, an autoimmune condition where the body produces antibodies against the thyroid, leading to underactivity. He emphasizes that avoiding gluten from grains is crucial, likely because gluten can fuel autoimmunity. Selenium, obtainable from just one Brazil nut, supports thyroid function and the immune system. Vitamin D3 in high doses further modulates immunity. This protocol addresses the root immune dysfunction rather than just replacing thyroid hormone.
Gluten can trigger autoimmune reactions in genetically susceptible individuals by increasing intestinal permeability and molecular mimicry. Selenium is a cofactor for thyroid hormone conversion and supports regulatory immune cells. Vitamin D modulates the immune system, potentially reducing thyroid autoantibodies.
A very important thing about that condition is to avoid gluten from grains. You need to take more selenium. You can get enough selenium from having one Brazil nut. Selenium also improves the immune system and so does vitamin D. So, you're going to need high doses of vitamin D3 for Hashimoto's.
