Phase out plastic containers
More and more studies are connecting certain plastics to health problems, with No. 3 (PVC) and No. 7 plastics that contain bisphenol A (BPA) raising the most warning flags. BPA is also found in many plastic takeout containers and canned food liners.
No. 6 plastics (polystyrene, also known as Styrofoam) also leach chemicals into food and drink. While Nos. 1, 2, 4, and 5 plastics are considered safer options, we suggest storing your food in glass containers, and choosing a stainless steel reusable water bottle for bringing beverages on the go.
