Here's a blog expanding on this study.
The author is a rather extreme zero carb enthusiast but he is usually right on the money on this subject.
Some quotes I think are relevant:
"It’s significant that they are beginning to understand the role of sugar in this process yet they are still trying to rationalize and make it fit within the comfortable confines of their diet-heart beliefs. "
"This “small” study is likely one of the best studies they have at their disposal yet they find some way to marginalize it and say it’s not relevant in some fashion."
"they refuse to acknowledge the finding that the low-fat diet was not protective against anything."
"For once in my life, I advise you to listen to the American Heart Association and cut your consumption [of sugar] and that of those you love by any means necessary!"
