Polyunsaturated fats cause the most damaging effects on your thyroid compared to any other food. They are responsible for a number of direct and secondary effects that suppress your thyroid.
Direct Effects of Polyunsaturated Fats on Your Thyroid Polyunsaturated fats block your thyroid from functioning on three different levels.
1. Polyunsaturated fats block the signal that tells your thyroid to secrete its thyroid hormones. So, right from the start, your thyroid won’t be releasing enough thyroid hormones to fully support your cells.
2. Polyunsaturated fats block the transportation of thyroid hormones in your bloodstream to your cells by tying up the transport proteins responsible for delivering these essential hormones.
3. Polyunsaturated fats block the responsiveness of your cells to the thyroid hormones that eventually make it to your cells. This makes your cells require even more thyroid hormones to produce the same amount of energy and maintain a healthy metabolism.
