When you are looking at your diet it is useful to focus on the carbohydrates content of your meals. All of these change into glucose once inside us. I get so fed up with the way newspapers focus just on ‘sugar’. There are plenty of other carbs. As someone with Diabetes we do not make enough insulin (or any in the case of T1) to balance the glucose in our blood stream. If you look at how many carbs you are eating you can then do swaps and/or reduce portion sizes of carbs to restore the balance. I found this basic outline useful when choosing veg
If they grow
- under the ground they are high in carbs
- above the ground they are medium carbs
- on the ground they are low carb
