Looking for any information out there on the saftey of using canned foods. Being on a low income and from a busy background, it is often easier and cheaper to buy some canned foods. The only two I regulary consume is a diced italian tomato mix, with garlic, onion and basil, no preservatives or additives, and wild caught pink salmon. Maybe totalling 6 cans in total between both per week. Is there any dangers involved with the can's or does the simplicity, ease and cost effectiveness outweigh any negatives?
Quick answer -- canned salmon is okay, actually quite good given where you live. Canned tomatoes -- not bad if you have no alternative but BOXED would be much better. Acid in tomatoes, specifically, reacts with the metal in the cans and leaches bad chemicals that you then ingest. I did exactly what you are proposing last year -- lived in Namibia and had no other options (other than fresh). But if you can get something like POMI in a box, that would be preferable.
I would agree with Cave Tomboy above, if you are left with no choice select which is necessary and limit consumption of canned products per week.
Can you purchase fruits and veggies in season and cut and freeze them for future use? Box or enclosed in glass tomatoes are becoming more available but still pricy, perhaps purchase in bulk, balance the skin off and freeze as well?
There are specifically BPA-free cans. You'd have to do some digging on the Internet, but why not limit your consumption to these if you are going to be using cans. My vote it eliminate them altogether, especially if you are feeding children from them.
