Rice (arsenic), large fish like tuna and swordfish (mercury), leafy greens (cadmium), spices (lead), chocolate (cadmium and lead), and baby food (multiple metals) are common sources.
How to reduce heavy metal exposure from food?
Wash and rinse rice before cooking, vary protein sources, choose smaller fish, wash produce thoroughly, and use CheckIt AI to identify products tested for contaminants.
