How does that happen? Doesn't this imply government interference in people's lives (eat this, eat that, exercise etc.,)? Given that such advice is frequently shown to be wrong, this is problematic.
The NHS doesn't seem to incentivize prevention of diabetes in the UK. To quote 'UK Diabetes': "Diabetes is the fastest growing health threat of our times and an urgent public health issue. Since 1996, the number of people living with diabetes has more than doubled. If nothing changes, it is estimated that over five million people in the UK will have diabetes.". This disease largely results from personal choices often made on the basis of misleading information.
