Hello Mark, welcome to the forum.
I have also been living with Diabetes for around 10 years, and also in the first few years was very confused by the sometimes contradictory information and advice available.
There is no 'one-size-fits-all' though and there was a lot of trial-and error before I found a solution that worked for me.
Do you have a blood glucose meter? Using one of these was the main things that helped me worked out what foods spiked my blood sugar levels, and eventually led to an eating pattern which reduced my readings and keeps them at a steady level.
If you don't have one then
SD Gluco Navii is one that many people use, and
test-review-adjust gives information on how to go about testing.
One of the areas that advice varies on is how much carbohydrates to include. For me I found that it is not just the obvious sugary things (biscuits,cakes, etc) that causes spikes. but also the starchy carbs (e.g rice, pasta, potatoes, bread )as these are a large source of glucose. The amount and exact items which individuals can tolerate these varies widely, which is where testing helps to find out what is right for you.
I also avoid most processed food, eat lot of 'above the ground' vegetables.
I find that this plan not only keeps blood sugars down, but I also feel a lot better and have more energy.
I have read that low-carb eating over a period of time can be harmful, but I've been doing this for several years and haven't fallen apart yet. BUT if you read the forum you will find that others have found different solutions that work well for them.
So it is worth taking the time to try things out and find the right solution for you, and my theory is that if I can keep blood sugars down, and generally it 'feels right', it may not be perfect but it is the best I can do for me.
It is worth reading around the forum and getting other views, and please ask any questions and let us know how it is going for you.
Very best wishes
