Yes, diabetes is a very individual disorder. I suspect type 2 has several sub types.
I am not gluten or lactose intolerant, but when diagnosed with type 2 diabetes in 2003, I had embraced ovo-lacto vegetarianism for more than 30 years and built up a repertoire of vegan recipes. Fast forward 10-15 years and I found diabetes management increasingly challenging. Rather than resort to medication, my solution was to include animal protein in the form of fish and seafood in my diet. I do not eat meat or poultry, but do include butter.
Breakfast is my favourite meal of the day.
In Summer:
I enjoy two poached eggs with a knob of butter, slices of avocado and some tiger prawns, seasoned with one or two grindings of black pepper.
Another favourite combination, when I have a little more time, is poached eggs, scallops and asparagus spears garnished with a generous knob of butter and some chopped flat-leaved parsley, all seasoned with black pepper.
Unfortunately, the English asparagus season is brief, but I make the most of it, while it's available.
At weekends, I often have two eggs scrambled in butter, sautéed chestnut mushrooms and a tomato, garnished with flat-leaved parsley or chervil and seasoned black pepper.
