Fruits are very important for everyone and for diabetics, even for insulin-dependent diabetes, NEVER fruit juices!

Concerning Diabetes:

Excellent:
Berries[raspberries,blackberries]
Strawberries
Guava
Kivi
Apricot
GRAPEFRUIT [if you don’t use statins
and some other medicines]
Avocado
Coconut [“the white meat”]
Goji [in small amounts]

Eat also the following fruits but a bit more in moderate amounts:
Blueberries,
Apples
Oranges [NEVER JUICE]
Mandarins
Peaches

Even in smaller amounts:[but for sure allowed, especially after a meal]
Grapes
Pinapples[Ananas]
Mango
Cantaloupe
Watermelon
Sweet cherries

Not connected to fruits but very important for diabetes:
Pulses are vital for diabetes: black beans, lentils, chickpeas[hummus], soybeans etc
Use a pressure cooker for pulses!

There is so much more, but these were just a few hints.
I just sent a mail about fibres and diabetes.
