Refrigerate cooked potatoes
Cook potatoes or other root vegetables, then chill them for about 24 hours before you eat them. The cooling process turns high-glycemic vegetables into low- or moderate-glycemic vegetables, and that transformation helps keep your blood sugar levels more stable. Even if you reheat the veggies, this trick works. As a bonus, cooking with extra-virgin olive oil helps keep the veggies from slowing down your metabolism.
