I cannot always purchase frozen beans (pintos, great northern, etc.). So when I do buy canned, I buy organic and I rinse the beans in a colander under cold water. It washes off all the preservatives and additives and makes me feel better about using beans in a can.
I haven't found any beans with under 2 grams of sugar per serving. Does anyone have any suggestions of a brand that does?
I do however purchase only frozen and fresh vegetables and organic meats.
