Almonds
Almonds provide a healthy, low-carb mix of monounsaturated fats plus magnesium, which is believed to be instrumental in carbohydrate metabolism. A large study out of Harvard University found that high daily magnesium intake reduced the risk of developing diabetes by 33 percent. Therefore, including more magnesium-rich foods like almonds, pumpkin seeds, spinach, and Swiss chard in your diet is a smart move.
