Are there any foods that help with tanning?

Yes. I'm not sure what those are exactly yet. I know there are because Dita Von Teese doesn't eat them in order to stay white.. Which is why I'm looking too.. Any foods with Canthaxanthin in it. ketchup, Ocean Spray cranberry juice, etc.

It's also found found naturally in foods such as: Mushrooms, eggs, fish.

Fish: Carp, Golden Mullet, Sea bream, Trush Wrasse, Pacific Salmon, Farm raised trout.

Canthaxanthin isn't exactly good for you. google it.
