Lead is no longer allowed to be used in canned foods, but the lining of the can often contains BPA, a coating that can contribute to our overall toxic ‘load’. You can find cans that are labeled “BPA free” but often the alternatives of BPS or other coating material is no better. So, while you might use canned goods occasionally, whenever possible try making your own beans and storing them in glass containers for use later in the week. A slow cooker is great for making beans very easily (and less expensively). Just remember to soak them overnight in water before cooking them to optimize digestion. Best!
