Frequently Asked Questions

Which foods have the most heavy metals?
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.
Are PFAS in food packaging?
Yes — PFAS 'forever chemicals' are found in microwave popcorn bags, fast food wrappers, pizza boxes, and other grease-resistant food packaging. They migrate into food and persist in the body.
