This article breaks Betteridge's law. The answer is not "no", but it might not be "yes". In fact, the article promotes the viewpoint that sun exposure is actually good for you, whereas butter is probably not essential.

If the sunscreen recommendations turn out to be too strong, this would be good news for me, as I have never liked having to apply sunscreen and dislike the scolds who push it on me when I don't feel I need it. But the article glosses over the fact that people who tend to burn rather than tan get more melanomas, and that melanoma can be a very insidious cancer. So, if I know I'm going to get a lot of exposure (beach, air show, whatever) I am going to use sunscreen to prevent burns.
