A little late to the party here, but oh well. I love potatoes. I grew up eating them almost every single day out in the rural countryside of southwest Virginia, homegrown from the garden during the summers, and I've never had any issues. They are the one food, to me, that I can rely on (asides from meat) to not cause any digestive/lingering (if anything, they aid in digestion) issues when I eat them. My favorite method of cooking them is rubbing them with melted coconut oil and throwing them in the oven on 350 for an hour.
