The case for eliminating sugar. All of it. - Vox

The other point you make is also very important. Clearly there are people who live very long, happy lives eating significant amounts of sugar. Maybe it even makes them healthier, who knows. Anything is possible. I get emails from these people regularly now, often explaining that they are living proof that my theory, as one such [correspondent] put it two days ago, is bullshit. If I’m in a punchy mood, I write them back and say something along the lines of, “My Uncle Max smoked two packs of cigarettes a day, lived to be in his nineties, and died of old age. Does that mean cigarettes don’t cause lung cancer?”

And the same logic holds. The fact that some people clearly tolerate sugar, if not thrive on it, is simply not evidence that those of us who are obese and/or diabetic didn’t get that way because of the sugar we, or our mothers, or our mothers’ mothers consumed.
