These sweet treats aren’t forbidden. Although they do contain sugar, the rate at which it enters the bloodstream is slowed by fiber. Fruits with a red, blue or purple hue might be particularly beneficial, because they’re loaded with anthocyanins, compounds that heighten your body’s sensitivity to insulin.
Nuts and Seeds
Craving a snack? Grab a handful of nuts. Even though they’re high in calories, they’re also packed with filling protein and healthy fat that can help keep your weight in check. If you’re a fan of walnuts, you’re especially in luck, because their high level of polyunsaturated fatty acids improves the body’s sensitivity to insulin.
Green Leafy Vegetables
Pretty much everyone, with or without diabetes, should eat a lot of veggies—ideally at least three servings per day—and green leafy types, including spinach, kale and such salad staples as romaine, should top the list. They have high fiber and water content that satiates your appetite on fewer calories, and they’re an important source of magnesium, which improves the body’s ability to turn glucose into energy and keep your metabolism humming (a process that is impaired in people with diabetes).
