Not a fruit in the culinary sense, but avocados are a great choice for people with diabetes.
They contain zero sugar and a whopping 7 grams of fiber per 100 grams.
Even better, they are high in healthy monounsaturated fats. Research shows diets low in poor quality carbohydrates and high in monounsaturated fats can improve insulin sensitivity.
Avocados are great in a salad or as a dip. They are even delicious on their own; just add a pinch of salt to taste.
