So - it's important to differentiate between "bad carbs" which I assume everyone to mean over-processed, and mostly simple carbs like pasta, sugar, etc. - and "good carbs" - fruits, vegetables, whole grains (which can be good or bad depending on YOU.) I can't handle grains at all (except for rice), so I just don't eat those. However, it's important to recognize that even starchy carbs can be important to your health. Pre-biotic starches (sweet potatoes, plantains, yuca) are the preferred food for some of the probiotics that colonize your gut. Doesn't matter how wonderful your probiotics are if you're not feeding them!
