looks like 2 types of nuts/fruit both called chestnut. one stretched longer and a light shade of brown
Agreed.
Now lets move to my initial question which I posted, do they have any effect on controlling blood sugar? Have you tried it for managing diabetes?
Would chestnuts not be mostly slow burning carbohydrates? I am no medical professional but that sounds like a good way to avoid sugar spikes/drops while keeping a consistent blood sugar level.
