How to keep your health up in Beijing?

Everyone knows how poluted Beijing is with all it's powerful manufacturers and no wind. How to keep your energy up and your immune system high? Your skin sufferes, your hair suffers from the hard water, sun sun sun, teasing your hair, makeup every day--breathing in the dust. The only way I have found to not get sick, is to take suppliments. But I really dont like vitamines, so I actually take live suppliments--you know, the stuff you find in your local raw food market like www.quintessence.com. I found one suppliment that I really like so much because it is grownd up wholefoods. Fruve. Its like eating a ton of vegetables and fruits, but in a concentrated dose.
