In a paper published in the Journal of the National Cancer Institute, Dr. Goran Bjelakovic (a noted anti-supplement warrior and well known harmaceutical shill) along with Dr. Christian Gluud insinuate that men taking multivitamins seven days a week have a much higher risk of dying of prostate cancer than those who take none. They further go on to dribble that their findings “underscore the possibility that antioxidant supplements could have unintended consequences for our health.” You know, if I were as bad of a scientist and published garbage like this, I wouldn’t be allowed to speak at any conferences ever again. There are so many flaws and misjudgements in this as to be embarrassing to the National Cancer Institute.
Here are a few problems off the top of my head.
- Men who have been diagnosed with prostate cancer are more likely to take multivitamins than those with no health issues. This was not looked at.
- The use of multivitamins was done using an intake questionnaire which is notorious for false numbers.
- The authors had no idea how long any of the people in the study used the multi vitamins a truly serious flaw.
- They claim that the population in question was “well nourished” despite a lot of evidence to the contrary. Our food supply is notorious for poor nutrient levels (see my blog).
- They used a cohort study which does not look at all of the variables possible. Statistics are easily manipulated (as they are here) to find something you want to find regardless of whether it really is there or not.
- There is no way, using the data supplied that a causative relationship can be developed. The authors admit this yet make conclusions that suggest a causal relationship. This is scientific dishonesty at its worse.
There are more problems with this paper but my biggest issue is how it got out of peer-review unless it was done nefariously, with a pointed agenda attached, aka anti-supplement. As I mentioned earlier, these are well-known anti-nutrient shills and this should be made very well known before giving any credence to the paper.
Shame on the National Cancer Institute.
