4. Sour Cherries
Fruit does contain natural sugar and it will raise your blood sugar, but some fruits still score low on the glycemic index and can be safely eaten on a diabetes diet. Sour cherries are a great example.
They contain a compound called anthocyanin that has been found to protect against both diabetes and obesity. Sour cherries have a relatively low GI score, too. Only grapefruit scores lower, so both of these fruits can be a great substitute for sweeter bananas, pears, and apples.
