Canned goods are great, they last, keep the nutritional values, packaging can be recycled, etc
The ‘they last’ means also less trips to the store, and less logistics is good for everyone and everything.
Unless canned food is acidic, then the cans are layered in plastics & are basically plastic bottles with extra steps.
Perhaps there is even an argument to be made how a large scale industrial processing can be (which doesn’t man is, but in proper countries it should be) much better, not only precise, but clean, with in some cases inherently far better ingredient quality (at least because of timing the ingredients), and more efficient too. It just takes less to implement an extra precaution or control in such an environment vs a big kitchen (or just someone mixing the ingredients at the store).
Often canned goods use no or at least much less preservatives compared to ‘fresh’ counterparts, simply bcs they just aren’t needed (and either way it’s cheaper to perfect the mechanical preservation processes than adding extra stuff in).
