I recently gave up eating takeout every night, but I’m too lazy to cook, which led to me replacing it with basically nothing but canned food. Like I’ll mix a can of beans and a can of mixed vegetables together, put half in a bowl and put the other half in a container for tomorrow, put salad dressing on it, and then that’s my dinner. I also eat a half can of fruit per day, because I found the shelf life and inconsistencies with produce to be too annoying.
On the one hand, I think I’m eating better than I was when I was doing nothing but takeout. My salt consumption has plummeted, and in general, I think the nutritional facts for my canned meal are better across the board than the takeout meals I was doing.
On the other hand, if there’s some long term issue with eating too much canned food, then I’m definitely going to be affected by it. I was thinking cats lead pretty good lives with nothing but canned food, so maybe I’ll be ok.
Anyway, am I going to die a horrible canned food death, or am I ok?
Canning frequently requires processing and heating. These have consequences for some vitamin levels, so they’re not exactly the same. Vitamin C is one of the bigger losses in canned food, often 60% or more because it hates oxygen and heat. Frozen fruit and vegetables are typically better for that reason, but canned is still fine if you account for it and your cans are also BPA free.
Assuming both canned and frozen foods are manufactured in ideal circumstances otherwise.
