BPA Exposure and Cardiometabolic Health: What One Large U.S. Study Found

Educational only — not medical advice.

Bisphenol A (BPA) is a chemical used in the production of polycarbonate plastics and epoxy resins. These plastics are commonly found in food containers, canned food linings, and some water bottles. Because BPA can migrate into food and beverages, researchers have become increasingly interested in its potential effects on human health.

A widely cited analysis published in JAMA (September 2008; 300(11):1303–1310) used data from the National Health and Nutrition Examination Survey (NHANES) to explore the relationship between BPA exposure and chronic disease risk in U.S. adults.

What the study examined

Urine samples from 1,455 participants were tested for BPA levels. Researchers then compared BPA concentrations with the presence of:

  • Coronary heart disease

  • Heart attacks

  • Angina

  • Diabetes

  • Liver enzyme elevations

What the researchers found

Higher urinary BPA levels were associated with:

  • A greater likelihood of coronary heart disease

  • Increased odds of heart attack and angina

  • Higher rates of diagnosed diabetes

  • Elevated liver enzymes, which may reflect liver cell stress

The findings do not prove that BPA causes these conditions, but they highlight a potential link between BPA exposure and metabolic or cardiovascular stress.

Why this matters

BPA is widespread in the environment, and exposure is common. For individuals looking to lower their toxic load—especially those with metabolic, cardiovascular, or hormonal concerns—reducing BPA exposure is a reasonable low-risk strategy.
