I just ate a bag of pretzels that said "USDA Organic" on the side. One of the definitions of organic means "made from living matter". To me this equates to things like lettuce and cabbage, and those things have 0 calories.
Also, the government has approved them as Organic, which means you are probably free to eat as many as you want while getting the same effects as if you were to just eat lettuce all day long.
There are a lot of things that are labeled as USDA Organic, like cheeseburgers, etc. Go out and see what you can find that is USDA Organic so you can finally be healthy!
