There are some companies like MonaVie and LifeVantage putting out “peer reviewed studies” in an attempt to market their product as being helpful for medical conditions. I think much of that logic was covered well here: PubMed, Impact Factor, Peer Review Journals, and Fraud.
A reader sent me a story that caught his eye Salt wars: New study says a dash or two is OK. One of the things you’ll notice about this study is that it had 30,000 participants over 4 years. When the results showed that adding salt to one’s diet may be okay in moderation a doctor cautioned:
“In a commentary in the same journal, Dr Paul Whelton of Tulane University in New Orleans says the study results should be read with caution, noting problems with the way the researchers estimated salt intake based on a single morning sample of urine.”
What I wanted to point out here is that even independent researchers who have tremendously large scale trials of 30,000 people over years can yield results that the public should be cautious with.
It is interesting to compare that to the MLM studies where they have at most 30 people over a couple of months… and every one that I’ve seen has been done with some kind of biased connection to the MLM company, which is anything but independent. No logical person could trust such a study.
