This study monitored for 25 years, but only asked people what diet they were following at their induction, and then 6 years later. so does not take into account dietary choice changes after that 6 year follow up. Rubbish. Remember that this study is based on what participants reported as a diet 25 years ago, and does not take into account modern eating habits and advertising hype.
The people doing the study acknowledge that they had very few subjects following a plant based diet, but their conclusions rely very heavily on their evidence. Again this shows a distinct bias IMO.
Declaration of interests
LMS receives grant funding from the California Walnut Commission and Dairy Management Inc, which was not used for this project. SC reports grants from the National Institutes of Health (NIH), and personal fees from Novartis and Zogenix, outside the submitted work. All other authors have no competing interests.
No wonder they are saying nuts are best source of fats.
I have not yet studied these reports in detail, so this commentary of mine is only a first impression.... Watch this space while I wind up my BS detector in earnest.
Edit to add: On second readthrough it seems to be reasonable to suggest that the bulk of the LC diet adherents 19 years ago were following Atkins#1 diet plan, which was a LC low fat high protein diet, which did show up some adverse health outcomes. It has since been revamped as a moderate fat limited protein diet similar to LCHF, but this change is unlikely to be covered by this study. This may explain their abhorrence for Low Carb and may actually be the trigger that started this study in the first case.
