Along with vegetables, vegans eat a lot of fruit as not only are they delicious and healthy, but they contain the nutrients you need for a balanced diet. Many fruits contain a lot of sugar, but some have a low enough glycemic count to be appropriate for diabetics as well. Since fruit contains natural sugar, it is something you can enjoy as a vegan and diabetic. Enjoy fruits like apples, blueberries, and grapefruit. Avoid fruits that sit in syrup.
