Onion is not bad for a diabetic but as with any vegetable, it will effect your blood sugars. I have been a diabetic for many years and things still surprise me on how they can effect blood sugars.
Lettuce by itself can lower blood sugars as it works as a flushing agent
Bananas will raise blood sugars but not very much or very fast.
Real Lemon will lower blood sugars
Being diabetic has taught me that it is a game of balance and you can't be 100% at figuring it all out as your body reacts differently to the same thing depending on the other conditions around.
