CAN the BPA. Seek out brands with BPA-free cans, or, choose to buy foods in glass jars or Tetra Pak containers, especially if the food is acidic. Pretty much all cans in the US are lined with BPA, especially if acidic foods like tomatoes or if vinegar or lemon juice are added as preservatives. It seems the acidity eats away at the more natural plant-resin lining. Here is a list of some USA brands that don't use BPA in cans. Tomato Options: Eden Organics glass jars, Pomi by Boschi Food & Beverage of Italy (in boxes), Trader Joe’s (in Tetra Pak box containers). Do your best and please don't stress!
