Full fat is diabetic friendly.
Low {almost anything} is generally not diabetic friendly because the key selling points of 'special' foods are based on out dated theories about what makes you fat, thin, healthy etc.
So don't go for anything that has a special label - just avoid all starchy things such as bread, pasta pizza, rice and root vegetables such as potatoes and parsnips. Sadly, that includes breakfast cereals, porridge, pulped fruit in smoothies and all sorts of fun things.
Eat naturally - eggs, full fat cheese, full fat milk, double cream, meat (assuming you are not veggie) salads, green veggies.
Avoid pre-packaged and processed foods as much as possible.
Read the labels for %carbohydrates of which %sugar - and keep those low.
Strange things pop up - like skimmed milk can spike your blood sugars because it is mainly lactose - a sugar.
Read the labels on milk and cream and you will find that double cream has the lowest carbs.
