Hi and welcome. AS you may have gathered already there are loads of people on this forum you can talk to. Virtually all of us have diabetes of different types and will try to help you understand the condition and take control of it. You've already had some very good diet advice. It is a bit confusing at first but give it time. The nurse was right about bananas and in general exotic fruits need to be kept small as they have high sugar content. In general root veg are quite high in carbs so keep portion sizes down. Beans and lentils, although carby, are low-GI and with good fibre so are quite a good choice as they are absorbed slowly and fibre is an essential part of diet
