> There's definite leaching of plastic compounds into food, which gets exacerbated when heated. My concern is the number of unknown unknowns. BPA became a big part of the consciousness a few years ago, and now it's PFAs, but what else?
PFAS and BPA are not used for (multi-use) food containers I think. Don't get me wrong! Avoiding throwaway packaging, where possible, absolutely makes sense. I specifically mean to find the culprit with Tupperware (or multi-use plastic food containers in general).
> My general view is that glass is super-durable, microwave-safe (I would never microwave Tupperware), and the cost tradeoff is minor, so it seems worthwhile.
Glass breaks faster than plastic containers (usually). I still use glass containers, but I am always aware that they break relatively easily.
Regarding microwave-use I am with you. Not a fan of microwaving plastic, even if it is safe for many plastic materials (the term plastic is vague I admit).
