Brazil nuts have the highest amount of selenium of any food on the planet ounce for ounce. Eating Brazil nuts can reduce inflammation, support brain function, improve your thyroid function and heart health, speed up your metabolism, and support healthy blood sugars. Your thyroid contains high levels of selenium, which is used to make and metabolize thyroid hormones. These hormones regulate many metabolic functions in your body, including how many calories you burn. Selenium also plays a major role in improving insulin resistance, and lowering glucose blood sugars, HbA1c, and bad cholesterols.
