Data for bowel cancer incidence was from World Cancer Research Fund International.
There's mortality data from NZ MOH here
As mentioned, the obesity ranking tables on wikipedia use WHO data.
There's a section on epidemiology of Type 2 diabetes on wikipedia here.
As I mentioned, that's probably hugely under-diagnosed in developing/third world nations, but also as it is another disease that's age-related, like cancers, heart disease etc, raw data on mortality per 100,000 is not what should be looked at for cross-country comparisons - it needs to be age standardised. If the average age of the population is say 20 with high birth rates, but life expectancy low due to death from a multitude of other causes so that there aren't many people surviving into their 60s and beyond, then raw data on deaths from diseases of aging (which these usually are) will appear to be low compared to NZ.
I agree that many people's diet sucks big time - they're poisoning themselves - but I'd dispute that's mainly because of big macs or tacos. Stuffing your face full of Tim Tams because you think you can still do that and look like the girl on the TV ad isn't a great idea.
I think I read in Denmark that they've banned ALL food advertising on TV at times where childrens shows are screened. I think that's a great idea - it saves all the arguing about what's healthy and what's not - guaranteeing that all unhealthy food is eliminated from those advertising slots - and I'm 100% certain that not one child will suffer even slightly - let alone starve to death because they weren't reminded to eat by a TV ad. Perhaps they should extend that to banning all food advertising on TV at all times - because many adults don't seem to be a hell of a lot smarter.
