Teflon (t-fal and all other non stick pans, a good replacement is simply a seasoned carbon steel pan)

Use glass tuperwares instead of plastic.

Silicone cooking utensils only preferably, metal is of course okay, stay away from any other plastic other than silicone in the kitchen). Silicone is non-porous, cannot foster bacteria and burns at 400C rather than melt. I advise good quality silicone since curing is the predictor of durability and is what impacts price in silicone manifacturing.

Try to not smoke cigarettes specifically, cigars and pipes are fine even vaping. The reason is cigarette paper is sprayed with BFR (a flame retardant) so as to reduce the risks of cigarettes causing house fires if someone falls asleep with a lit one in their hands. PhilipMorris will kill you quicker with additives than tar from tobacco.

Avoid fast foods, as well as grease or water repelling clothing (even Gore-tex and others). They re PFAS coated, mcdonald's food for example is wrapped in packaging that does not stain despite the food being very greasy because PFAS coatings are heavily used in the ready-made food industry.

Try to avoid frozen meals or already prepared food you did not cook yourself (that sadly includes trader joe, I consulted for them once and they are not better than everyone else when it comes to forever chemical uses, Costco on the other hand is very careful manifacturing-wise and that is where i shop) since the packaging uses a lot of polyethylene and styrene which as an engineer myself I wonder how on earth we allow them in the food industry.

Canned food since the steel of cans is coated with a thin layer of epoxy on the inside ( this includes canned drinks and canned alcohols ), cosmetics, parabens for fabrics (dry cleaned clothes, enterprise carpet cleaning services, and artificial textiles such as polyesther in clothing, try to stick to natural cotton).

Finally the most important; all fragrances, cosmetics and UV blocking chemicals (sunscreen is horrible for your hormones). Fragrances in particular are terrible for the environment and for you as well. Non perfumed soap and detergents have a big impact on the environment. Finally, if you have kids, do not let them put non-silicon toys in their mouth, and avoid recycled paper products (toilet paper made of recycled paper for example).
