- Per- and polyfluoroalkyl substances (PFAS) such as Perfluorooctanoic acid (PFOA)are a class of chemicals used to make things non-stick, stain-resistant, and waterproof. Some microwave popcorn bags, fast-food wrappers, rain jackets and other consumer products use these chemicals’ slippery properties. Unfortunately, PFAS and their bi-products accumulate in the environment and may harm human health, potentially causing abnormal thyroid hormone levels, reduced immune system response, act as endocrine disruptors in males and females, and cancer.
- Fall produce, including apples, winter varieties of squash, kale and Brussels sprouts, whether eaten fresh, frozen or canned, provide healthful benefits, say registered dietitians, who offer tips to get the maximum nutrition from this season’s bounty. Leave the skin on fruits and vegetables. This is because plenty of the food’s nutrients are housed in the skins, which are edible and delicious. Cooking produce with fat makes certain nutrients more bioavailable, and adding spices like cinnamon and cardamom can boost antioxidants.
When recipes call for a non-stick pan or other non-stick cookware, try substituting it with cast iron or stainless steel. These durable alternatives serve the same purpose when used properly. There are many coatings and materials marketed as healthy alternatives to non-stick, but ceramic coated pans, cast iron and stainless steel are time-tested and proven to be safe. For cooking in the oven, ceramic or glass are good options.

There are many coatings and materials marketed as healthy alternatives to non-stick, but cast iron and stainless steel are time-tested and proven to be safe. If you already own non-stick cookware, consider the following while using to prevent the release of PFAS:
• Cook at medium and low temperatures and use ventilation.
• Never cook on high heat, as this may release PFAS into food or the air.
• Use wooden cooking utensils to prevent scratching the coating of the cookware, as scratches can promote the release of PFAS.
