In the newspaper the other day, they talked about what foods are best to eat for skin and hair.  I'll just quickly run through these, since I find the info beneficial to those who like to look and feel good. 

For Hair:
Brazil nuts (eat only one a day, otherwise you'll overdose on the selenium)
peanut butter


For Skin:
strawberries
green tea
tomatoes


For Nails:
egg yolks


Salmon and other seafood belong somewhere in there as well.
