“There are limitations to this study that merit consideration. This study represents observational data and is not a clinical trial; however, randomised trials of low carbohydrate diets on mortality are not practical because of the long duration of study required. Another limitation of this study is that diet was only assessed at two time intervals, spanning a 6-year period, and dietary patterns could change during 25 years.” This study is based on a 66 question FFQ (food frequency questionnaire) spanning a six year period. Do you remember what you ate last month? A year ago? Six years ago? Maybe a more modern version of these types of studies can be done if the subjects are required to take pics of everything they ate instead of reporting from memory on a questionnaire. “LMS receives grant funding from the California Walnut Commission” Oh? “SC reports grants from the National Institutes of Health (NIH), and personal fees from Novartis and Zogenix” Novartis and Zofenix are in the business of making statin drugs.
