Petra, my whole family is predisposed to diabetes, even those who exercise well and have always eaten healthily. It doesn't seem to matter what sort of eater you are in this family, we all end up with it in the end. Some of us are skinny, some of us are overweight but few of us are obese.
It is really offensive to be kept being told that diabetics have no thought for the NHS. In fact, if I ate how the NHS advises on my diabetic journey, I'd probably be on more medication and possibly even insulin. They advise that a 3rd of my plate should be complex carbs...definitely a problem for my blood sugars. It was only when I ate to the meter, I was able to see how disastrous the advice was. BTW, my blood sugars are well controlled so I am not speaking defensively because I don't control it; it just irritates the hell out of me that the moment people find out you are Type 2, you are stigmatised.
If we are going to look judgementally at people who enjoy some unhealthy sugary treats, let's also look at the people who enjoy their wine (full of sugar), alcoholic drinks, coffee and tea (caffeinated), salt, etc, etc. All of these things impact our health and can have repercussions for the NHS. What about people who don't exercise enough or maybe they play sport and get injured? All these things can be avoided and cost the NHS.
