Nutrition and Lifestyle Choices for Competitive Athletes

Princeton University (New Jersey, USA) put together this great spreadsheet on the optimal types of food, the effects of "bad" food, the importance of hydration, the effects of alcohol on performance and more.

Don't let this article define your health standards or nutritional pattern though, do your own research. They even say: "Not everyone’s plate will look exactly the same. AVOID comparing and get what your body needs. Play your game, not someone else’s." If you're trying to compete at the highest levels or maximize your health potential this isn't everything, by any means, but it's a good place to start.
