Hi What sweets are best for type 2 Diabetic
None, really
There are some made with artificial sweeteners which, on the whole, don't taste great and, as an added bonus, can upset your stomach a treat.
The only real option is to have chocolate with a high cocoa content. Aldi and Lidl both do similar products (90% cocoa, I think), with about 5g carbs per portion but they are a bit too bitter for me, though I can manage the next step down - 75% cocoa - which has about 7.5 g of carbs per serving.
Strawberries dipped in melted dark chocolate are another alternative to consider, but you'll need to exercise portion control
