Wait a minute - tomatoes are bad? Thankfully, no. Fresh tomatoes are super healthy and actually have cancer fighting properties. The canned variety, however, are a completely different story. There's a few reasons why you should ditch canned tomatoes from your pasta sauces and we're going to start with the can itself. Most cans are lined with BPA, the same cancer-causing chemical that can be found in plastic bottles.
In the case of tomatoes, BPA in the can lining is even more harmful than normal. This is because of the high acidity of the tomatoes. It tends to leech the BPA from the can and into the tomatoes, making it worse than sipping on a plastic water bottle. Buy fresh tomatoes and blend them up instead or buy tomatoes in a glass jar to avoid potential cancer.
