What a horribly unscientific infographic! UVA "ages" the skin and UVB burns your skin but also creates vitamin D? The truth is that UVA is a longer wavelength radiation that for the most part lacks the power to penetrate the skin, while UVB does do damage to the DNA. It's exactly that sort of genetic damage that "ages" the skin, in the terminology of the author. It can also lead to cancer.
Eat pretty much any fatty fish as is common in arctic cultures anyway, and you'll be fine. Ethical vegans can eat lots of mushrooms.
