Can lead exposure harm cardiovascular health?
Lead exposure is linked with cardiovascular disease burden. Old pipes are a water issue, and some glazed or low-quality cookware can add lead to food, especially with acidic cooking.
Short answer
Yes. Lead exposure is linked with cardiovascular harm. This page should not pretend that one pan or one pipe tells the whole story. Lead risk adds up across water, dust, soil, paint, and food-contact items.
What the research found
A 2026 Frontiers in Public Health analysis used Global Burden of Disease 2021 data. It estimated about 1.48 million deaths and 30.0 million DALYs from cardiovascular disease attributable to lead exposure in 2021.
For cookware, a 2026 study in Journal of Public Health Management and Practice tested glazed-clay pottery sold near the Mexico-US border. Acidic food cooked in lead-glazed pottery had much higher soluble lead than nonacidic food.
What to do at home
Do not cook acidic foods like tomato sauce in old, imported, handmade, or cracked glazed pottery unless the seller gives clear lead-safety proof. For everyday food contact, choose stainless steel or glass when you can. For old pipes, use local water testing and a certified water filter, because cookware swaps do not fix plumbing lead.

What to use instead
For food-contact swaps, start with stainless steel or glass tools. For old pipes, test your water and use a certified filter because kitchenware cannot fix plumbing lead.
