Depending on the era, clay pots often had led glazing, which could leach out into acidic foods/beverages. Generally glass is going to be fine, as long as it’s not painted/coated on the surface that touches the food or your lips. That said, the cap is almost certainly plastic/plastic coated. Plastics are all suspect IMO, particularly in hot liquid applications (looking at you, Pho delivery). Aluminum seems like it would be fine, but the cans all use internal rust inhibiting coatings (which vary from beverage to beverage) that are also suspect. Parchment paper is fine, butcher paper is coated, as you point out. Oh, and your drinking water is probably full of microplastics. Personally, I use glass storage for leftovers, reverse osmosis filter for drinking water, only buy liquids packaged in glass, and try to buy whole ingredients/cook my own food. But I still sometimes enjoy a can of beer or a take out meal. I figure if there is a hazard, it’s dose dependent, and I just try to be a little thoughtful about where I’m picking up exposure.
