When I started testing I found that porridge was possibly the worst thing that I'd been eating. I no longer eat it or any other cereal hardly either! Healthcare professionals had all been telling me how good a food it was for a diabetic to eat. In fact, my GP had been trying to get me to eat porridge for lunch as well as breakfast. Quite amazing really!
As far as I am concerned, the message that all new Type 2s need to understand is the importance of cutting back on all starchy carbohydrates - i.e. cereals, bread, potatoes, pasta and rice. Doing that usually leads to a dramatic improvement in blood glucose levels.
In my opinion, from both my own personal experience but also from what I read on these diabetes forums, dietary changes are much more important than medication, weight loss and exercise in lowering the blood glucose levels of Type 2 diabetics
