I summarized several studies which found that selenium supplementation reduced inflammation and damage to thyroid tissue, lowered thyroid antibody levels in the blood, and improved the conversion of T4 to T3.

But many choose a vegetarian diet is… Read More

Earlier in January, US News & World Report issued its annual ranking of the best diets to follow for several different goals and health conditions, including weight loss. As you may know, the Paleo diet was ranked last in the “Best Diet Overall” category of the 32 diets they reviewed.
