Most important Med diet study has been retracted. https://qz.com/1305718/the-science-behind-the-mediterranean-diet-might-be-flawed-thanks-to-a-retraction-of-a-major-study/
I'm surprised about the retraction, given the general terrible state of nutrition research, but not surprised the research doesn't hold up after seeing this study last year on how money, not diet matters https://qz.com/1045037/the-mediterranean-diet-works-for-the-wealthy-and-well-educated/
I'm beginning to think my gramma knew what was up - everything in moderation and always leave a bite on your plate. And eat plenty of chocolate.
@susannah wow, a complete failure to account for obvious sources of bias, no wonder it was retracted!
