Looking for the very latest on nutrition science? Look no further: most of the results presented in this installment of the short news have not yet been officially published after their presentation on a conference of the Nutrition Society . I hope you don't mind that I decided to pool the most interesting of the latest studies from the Proceedings of the Nutrition Society in a single article. With the articles on vitamin D, B-vitamins, ketogenic diets in endurance athletes, and so on and so forth all being addressed individually, you can still skip studies you may not be interested in and get the gist (read the title and  the last paragraph of each bullet point) within seconds. As it is usually the case for short-news that are based on presentations at a conference, it will take time for the full papers to be written, reviewed and published. Accordingly, I cannot tell you how many eggs the subjects in the keto-diet study ate and whether they consumed their stakes rare or we...

Studies Confirm: Natural and Synthetic Vitamins Can Differ in Quantity & Quality of Effects! Vitamins A-E, B's & More

Pills or fruits, one are funky and useless, the other ancient and healthy!? In a 2000 paper in Medical Hypothesis , R.J. Thiel writes "[t]here appears to be a tendency to label those who profess that natural vitamins are better than synthetic ones as quacks" (Thiel. 2000). No wonder, after all, every good text book will inform future physicians and researchers that the difference between natural and synthetic alpha-tocopherol was a mere quantitative one. In other words, as long as you make sure that you administer 1.36x the amount of "natural" vitamin E in,   all-rac-α-tocopherol should do the exact same  as its natural cousin.

"What? Don't gimme that look. I did walk to the fast-food outlet. I swear!" - When it comes to how much they sit around, people love to lie... ah, I mean they often overestimate their activity level - especially the really lazy ones ;-) It's not always easy to find a "figure of the week" and actually the on I am going to present you today is not "week specific". It is rather related to yesterday's post on the statistics of the diabesity epidemic . That said, you may remember that the gap between "more" and "less" active individuals was widening, but on average the NHANES stats would suggest that the average US citizen is not sitting around much longer today (or rather in 2004) than 40 years ago. Now, the NHANES data is based on a questionnaire of which Healy et al., who have analyzed the accuracy of these self-reported activity levels in a 2010 paper (Healy. 2011), found that the difference between the real and the clai...

B-Vitamins & Diabetes: Protective or Causative?

Written by | published on
In a very interesting study, scientists from China and Japan ( Zhou. 2010 ) found that " long-term exposure to high level of the B vitamins may be involved in the increased prevalence of obesity and diabetes in the US in the past 50 years ". At first this appears to be counterintuitive, since we have been told over and over that B-Vitamins are not only good for our health, but that we could not even "overdose" them. While the latter has been questioned for years and certainly is not the case for e.g. B6 and niacin, even the former seems questionable, if you read the results from the above mentioned study: The prevalences of diabetes and adult obesity were highly correlated with per capita consumption of niacin, thiamin and riboflavin with a 26- and 10-year lag, respectively (R2 = 0.952, 0.917 and 0.83 for diabetes, respectively, and R2  = 0.964, 0.975 and 0.935 for obesity, respectively). [...] The relationships between the diabetes or obesity prevalence and per ca...
