Of all fruits and vegetables, tomatoes fare the worst when stored in cans. This is because tomatoes are very acidic and the acidity will cause the chemical that lines the cans to permeate into the food. Cans are known to contain about 50mcg of the toxic bisphenol-A, or BPA, which can severely affect adults and especially children.
Consumer Reports' latest tests of canned foods, including soups, juice, tuna, and green beans, have found that almost all of the 19 name-brand foods we tested contain some BPA.
Background: BPA is a toxic chemical linked to reproductive abnormalities, neurological effects, increased risk of breast and prostate cancers, diabetes, heart disease and other serious health problems.
Comment: You might want to consider avoiding tomatoes altogether as they are nightshades. The nightshade family also includes potatoes, peppers, okra and eggplant and is linked to chronic pain and inflammation.
Aluminium Poisoning
When food is stored in an aluminium can, over time, it will gather some of the aluminium that it is stored in. This is especially so with tomatoes with its high acidity.
To avoid the toxic BPA, avoid canned foods completely and consume fresh fruits and vegetables. Another way is to switch over to brands that use glass containers instead—especially for acidic foods like tomatoes.
Comment: Another good idea would be to learn how to do your own canning. Food preservation is a good skill to have and this way you can have more control over quality and avoid consuming added potentially toxic ingredients.
