Led Zeppelin, Black Sabbath … while you may be a heavy metal fan, your thyroid? Not so much. That’s because heavy metals, mercury in particular, are chemically similar to iodine — an element the thyroid needs and readily absorbs. When metals like mercury take the place of iodine at binding sites, thyroid hormone production grinds to a halt. The good news is you can naturally detoxify with fruits that are rich in pectin — a gelatin-like fiber that sticks to toxic compounds in the blood and flushes them out of the body through the urine. In fact, citrus pectin increased mercury excretion in the urine by 150 percent within 24 hours of supplementation, according to one study. As a weight loss bonus, research shows pectin can limit the amount of fat your cells can absorb. You’ll need about four pieces of whole fruit daily to reap the benefits. Grapefruits, oranges and peaches are all good sources, but since most pectin is found in the fibrous pith and peel, whole apples are one of the best.
