I dispair at the amount of healthcare professionals that live on a diet of junk food, and are over weight. The very same people who hand out advice about healthy eating. In my experience in working in a setting where at least twice a week the was a massive carbo feast, because someone was leaving, getting married or had a birthday, not once did I see a tray of left over meat, olives, or even salad, so the sugar overload is not restricted to special occasions.
I sorry if the nurses comment linking excess sugary food consumption to diabetes affends you, but I am sort of pleased, its not the full story but at least its a start, now we have to get them to connect bread and baked beans.
If you smoke you are more likely to get lung cancer and heart disease, not everyone who has lung cancer or heart disease smoked. As a society we have decided its better that people do not smoke, as a society I think the best thing on the evidence I have seen is we do not over consume carbs in any form.
