Avocado - I seem to be fairly lucky to be able to drive my levels lower over the almost 5 months I have been diagnosed. Although I don't take any medication, nor do I ever snack. I can't recall the last time I had a snack and I have a pudding perhaps once every couple of months? I have the odd glass of red wine, but otherwise I eat my meals, so my bloods will only be (potentially) raised three times a day when I eat. I'm discounting the odd cup of tea, with milk, to be fair.
I have reduced my carb intake, and average 90g of carbs a day, although, to be fair, sometimes it can be much lower. I defy most usual diabetic experience and have rolled oats for breakfast, which, with semi-skimmed milk and some added fibre, comes to 40g alone.
It took almost 3 months to get anything below 5, fasting, but now it's pretty stable, lower. I'm happy.
