Nonstick and stain-repelling chemicals are convenient, but in terms of health, they might not be worth it. Previously linked to infertility, high cholesterol, and ADHD, a September 2012 study published in the Archives of Internal Medicine also shows a connection between perfluorooctanoic acid (PFOA) chemicals and heart disease. Regardless of age, body mass, or the presence of diabetes or other diseases, researchers found that people with the highest PFOA levels in their blood were twice as likely to have cardiovascular disease compared with people with the lowest levels.

More PFOA avoidance tactics? Stay away from fabrics, furniture, and carpeting advertised as “stain repellent,” and eat fast food less – many fast-food containers contain PFOA-containing grease barriers. …
It may seem that there is a never ending parade of things to avoid, but what we can do reasonably is update our daily activities as we learn new things to stay as healthy as possible.
