I live in a sub-tropical climate and berries, except for strawberries, are very seasonal and expensive. On the other hand, Mango, banana, pineapple, oranges, mandarins, melons are all plentiful and relatively cheap and I have always eaten them. As a new type 2 (as result of steroid treatment) I have to give up these tropical fruits and buy frozen berries. Not happy! And because my diabetes is medically induced, giving up my fruits does not seem to do much good - my tests are all over the place. Never realized that living with diabetes was so difficult - but I'll get buy.Berries!
Strawberries
Raspberries
Blueberries
Blackberries
Test them though, some can, some cannot
Best of luck
