Hi Dollypolly. Welcome. I'm glad you have downloaded that book, you will find it a great help. It does come as a shock when your first told, but in a short while you'll learn a lot and probably end up teaching the practice nurse about
your diabetes, they often don't have very much training in diabetes and quite a few can't get their head round the fact that diabetes is very individual.
eg I can eat porridge others have to avoid it like the plague, some give wrong info too.
Its carbohydrates our bodies can't handle too well. Try to cut down/out on Things like potatoes, pasta, rice and bread especially white. Fruit juice is packed full of sugar as are grapes
These are fine
If you eat meat, meat is fine whatever colour it is excepting green of course

So are high meat content sausages and burgers.
Cheese, fish, some nuts are low in carbs, eggs cooked anyway you like.
Personally I don't eat anything that is not naturally low fat, ie low fat yogurts , as they often have more carbs that the full fat version due to added sugar to make them more palatable.
Sadly many T2s who are not on medications that can cause hypo's ( low blood glucose) are provided with a glucose meter, without a meter you cannot find out which foods affect you BGs (blood glucose) badly
If you want to test and can afford the ongoing cost of the test strips, the SD Codefree meter is the cheapest one to self fund, it's test strips are around £7 for 50 other brands are a minimum of £15 + for 50
As already said it's available from Amazon or directly from Homehealth
we use the mmol/L measurement in the uk, don't forget to claim vat back

You would need to buy more test strips and lancets as they normally only provide 10 each in the starter pack
