Studies can be deceptive, and mass media reports on studies can be even more deceptive.
For years, I have taken a daily Vitamin E supplement, and for many years I also took a fish oil supplement for Omega-3. At a semi-annual checkup at the VA hospital, my doctor told me that I shouldn't take either of those. Among other things, she said that Vitamin E causes prostate cancer in men.
My doc was a nice woman, but that's not enough for me. After the appointment, I started doing some research. I found studies on Omega-3 were interrelated with studies of Vitamin E. Ultimately, I decided to stop taking the Omega-3 supplement (and I still have most of a large bottle, if anyone wants it). It was what I learned about Vitamin E that was the eye opener.
It turns out that most over-the-counter Vitamin E supplements are synthetic and are based on "D-Alpha tocopherol." And, by itself, D-Alpha tocopherol has been linked in some studies with prostate cancer. However ... not all Vitamin E is synthetic D-Alpha tocopherol. The same studies reported that Vitamin E, even synthetic Vitamin E, comprised of multiple forms of tocopherol, are NOT associated with elevated risk of prostate cancer. So, rather than discontinue taking Vitamin E, I switched to a slightly more expensive version that's compounded from mixed tocopherols.
In my view, the only benefit to reading a mass media report on a medical study is to let me know there was a study. If you want to actually know what the study said or concluded, you have to read the study. Don't believe the media version.
