If you have no symptoms I would let well enough alone and eat a healthy diet without too much concern about starch. My understanding is that gut bacteria help break down starch so if you have no problems you may have a good gut. Maybe shifting your food would shift your bacteria and who knows if that would be an improvement. If I were you I'd skip gluten, sugar and processed food in general but not worry about healthy starches unless you start to experience symptoms. Just my opinion! Hope you continue to feel well!
