Especially in low season, canned food (like tomatoes or corn) may seem like a good alternative when fresh vegetables are out of reach. Unfortunately, many cans on the market contain a substance that is unhealthy – bisphenol A (BPA). It is used in the form of epoxy resin that insulates metal from food. It also penetrates into the veggies inside the can.
It’s the case of especially tomatoes because they are particularly susceptible to the absorption of this dangerous substance, which make of it really junk food. It is worth to know that the use of bisphenol A (BPA) has been banned in Canada, the USA and the Scandinavian countries. In the fall or winter, it is definitely better to choose silage and, for example, frozen vegetables (they do not lose their values and it is certain that they were harvested in the season).
