The Most Important Study of the Mediterranean Diet Has Been Retracted (qz.com)

Zorro shares a report from Quartz: In 2013, the New England Journal of Medicine published a landmark study that found that people put on a Mediterranean diet had a 30% lower chance of heart attack, stroke, or death from cardiovascular disease than people on a low-fat diet. It received massive media and public attention when released, and since has been cited by 3,268 other scientific papers. The study had tremendous impact on the field of nutrition and health science. Yesterday (June 13), however, the journal retracted the study -- providing a new reason for skepticism about how effective the now-popular Mediterranean diet really is.

The reasons for the withdrawal are complicated, having to do with the methodology of the study. As Alison McCook of the Retraction Watch blog writes for NPR, this retraction is the result of the work of John Carlisle, a British anesthesiologist and self-taught statistician. Carlisle has spent recent years analyzing over 5,000 published randomized controlled trials (the gold standard of medical science research) to see how likely they were to have actually been properly randomized. In 2017, he reported his results: at least 2% of the studies were problematic. One was the 2013 NEJM article on the Mediterranean diet.

    It has always been my firm belief that the key to a successful Mediterranean diet is consuming copious quantities of wine. Everything else becomes irrelevant once you've mastered that part of it.

    Please moderate the Parent GP posts correctly by verifying the truth of those posts before you moderate up or down.

    It is easy:

    1. Go to the slashdot summary. There are three links in that article. Verify that the third link is to this article.

    2. Scroll down in that article to, about the 17th paragraph, which begins "It turns out approximately 14 percent of the more than 7,400 study participants hadn't "

    3. Compare that paragraph and next to the quoted paragraphs in the GP post to confirm that they match, confirming that the GP truthfully quotes an article linked in the /. summary.

    4. Read the sentence in the parent post which states "Please kindly refrain from making up random bullshit and pretending you are quoting the article". Because in the previous step you have verified that the GP accurately quotes a linked article, yet the Parent emphatically and profanely states the opposite, conclude that the author of the parent post is a troll.

    5. Moderate the parent post accordingly. It belongs at -1, Troll, down with the goatse posts.

    6. Moderate the GP at least back up to what it default to when originally posted at, +2. Unless, using our own judgment, you can find a compelling reason otherwise to object to its content.

    7. Consider moderating this post up as you see fit. In the humble opinion of its author, it makes a helpful point: with little effort moderators can improve /. by assessing the truth or falsity of posts before assigning mod points.

  4. My apologies, kind sir by raymorris · · Score: 2, Insightful

    You are of course correct, the summary links multiple articles. I apologize. I was both wrong and rude.

    Normally I have mod points but today I don't, so I can't mod myself down. :)

    > The healthiest diet is a plant-based diet.

    Humans SUCK at digesting plants. We don't have the enzymes for it. We don't have the stomachs for it.

    The vast bulk of the plants we grow for our own use are completely inedible to us.
