With the summer beach season in full swing, it's time to start thinking about ways to reduce your exposure to harmful ultraviolet radiation of the Sun. Fortunately, public relations personnel Draznin is ready to educate you about a new strategy important to protect the skin from sun damage: eat more cocoa!
In a recent press release, Draznin offered to me on the track to the findings of a "featured" experimental adds the "mountain of studies on the benefits of cocoa". The results show that a certain type of antioxidant-rich cocoa "protected the skin from sun damage caused by exposure to UV rays," according the Draznin.
I thought I was above all the latest claims about cocoa-based products, encourage (but far from conclusive) cardiovascular effects of frankly dubious notion that chocolate is some sort of weight loss help. But chocolate as sunscreen? I don't see how this could work unless you were spotting it across your skin like Coppertone. (Not a look that I recommend).
For most of us, cocoa is something that we like to curl up with beside a warm fire on a cold winter night. Draznin now want to pack it in your beach bag along with the floppy hats and parasols.
As you can see, the enthusiastic Draznin claims are based on a study of 6 years of age, involving only 24 women, which was partially funded by the Mars Corporation. The researchers randomly assigned women receive a cocoa drink that was high in certain antioxidants known as flavanols (326 mg/d) or low flavanols (27 mg/d).
At the beginning of the study and after 12 weeks, women were exposed to a solar light Simulator and the redness of the skin was evaluated. Women high-flavanol Group had 25% less redness after 12 weeks than they did on the baseline, while the women in the Group of low-flavanol had no change in redness.
Interesting finding? Absolutely. And I'm not dismissing the idea that your diet can play a role in helping him to resist the adverse effects of exposure to the Sun, but as readers of this blog know, a tiny, short-term study, funded by the manufacturer is not proof of anything when it comes to health outcomes of the real world. And yet that did not prevent the Draznin of blatantly extolling the results.
The "argument" of this study, according to Draznin, is that cocoa consumption "should be part of your daily skin protection strategy and throughout the year."
Not surprisingly, Draznin also volunteered to tell me more about a particular line of supplements that contain cocoa flavanols claimed to be protective.
As far as I'm concerned, the only "takeaway" here is ludicrous lengths to which some public relations companies will promote a product. It is also a reminder that some companies will stretch any shred of evidence to give your product a veneer of scientific credibility.
One more reason for journalists and consumers to look critically for health claims and especially to seek an independent perspective on the importance of supporting research. HealthNewsReview.org has a very useful Toolkit-a great place to start working with this type of analysis.
