Are heavy metals in herbal teas a concern?
Yes. Heavy metals like arsenic and lead in some foods and products are worth actively reducing in your diet.
What's actually in it
Heavy metals like arsenic, lead, cadmium, and mercury occur naturally in soil and water. They enter food through contaminated soil, irrigation water, and food processing.
Some foods concentrate heavy metals more than others. Rice absorbs arsenic from soil and water. Leafy greens accumulate cadmium. Some spices have been found to contain lead from contaminated growing regions or processing.
