1. Avoid the worst plastic offenders If you check the bottom of any plastic container, you’ll see a number (1 through 7) inside a triangle made of arrows. The worst plastics are:#3 – Polyvinyl Chloride, an extremely toxic plastic that contains dangerous additives such as lead and phthalates and is used in plastic wrap, some squeeze bottles, peanut butter jars, and children’s toys#6 – Polystyrene, which contains styrene, a toxin for the brain and nervous system, and is used in Styrofoam, disposable dishes, take-out containers, plastic cutlery#7 – Polycarbonate/Other category, which contains bisphenol A and is found in most metal food can liners, clear plastic sippy cups, sport drink bottles, juice and ketchup containers 2. Use non-plastic containers Carry a reusable water bottle and travel mug wherever you go. Pack your lunch in glass (Mason jars are wonderfully versatile), stainless steel, stacking metal tiffins, cloth sandwich bags, a wooden Bento box, etc. Take reusables to the supermarket, farmers’ market, or wherever you’re shopping, and have them weighed before filling. (Here is a list of 7 plastic-free lunch options.) 3. Never drink bottled water Buying bottled water in North America is absurd, especially when you consider that bottled water is less regulated than tap water; it’s usually just filtered tap water; it’s exorbitantly expensive; it’s a gross waste of resources to collect, bottle, and ship it; and it results in unnecessary plastic waste that’s usually not recycled.

While this mentality has been the norm for years at special bulk food stores, it’s fortunately becoming more common in supermarkets. You’ll save money in food costs and, if you drive, in the gas used for extra trips to the store. Search for items such as large wheels of cheese, without any plastic packaging, and stock up on those whenever possible. (Read Why I'm hooked on grocery shopping with glass jars.)
