Raw Potato and several other foods contain resistant starch which significantly lowers blood sugar. Just Google "resistant starch blood sugar" for more info. It works. Just a few bites of raw potato will do it. They also sell potato starch which you can mix into a drink. DO NOT EAT LARGE AMOUNTS OF RAW POTATO. I don't think it would kill you or anything but resistant starch is an anti-nutrient so more is not better and I'd guess you could get an upset stomach from too much. Diabetes drugs also have their drawbacks so I still think this is worth doing. Obviously do NOT eat any part of the potato that's green or sprouted. That part is poisonous. Again, just Google "resistant starch" for more info.
