Thats just plain wrong sorry. Sugar in moderate amounts is not a problem at all. But in the North American diet which pretty much spills over to large parts of the world sugar is so over represented in the makeup of so many foods that even if you cut out sugar as such you would still be getting a substantial amount in your overall food consumption.I stopped reading the article when she endorsed the Sugar industry. The single best thing anyone can do for health and longevity is to cut the sugar from the diet.
If you followed a more Mediterranean diet you can add a judicious amount of sugar for taste with little or no health consequences.
