Hello again,
All carbs turn to glucose once inside the system. It doesn't matter what colour they are, although the brown varieties take a little longer to digest. It makes sense that we should reduce all carbs as extra glucose in the blood stream is not what we need. The starchy ones are the worst culprits - bread, potatoes, rice, pasta and cereals. We also need to be careful of fruits and milk.. So your doctor is not quite right.
The good news is you can eat dairy foods (butter, full fat yogurt, cheese, cream) as many eggs as you wish, olive oil, mayonnaise, bacon, any meat and fish especially oily fish, most vegetables that grow above ground, salads, a few tomatoes, mushrooms and lots of other things. You will soon learn which foods your body can tolerate (because we are all different in our tolerance levels) by testing as advised, before and after meals, and you will learn if you need to avoid a particular food or simply cut down the portion size. The secret is to reduce the carbs. If you do that, your levels should come right down.
Do spend some time reading round the forum, and ask as many questions as you wish.
