CrossFit is a lifestyle characterized by safe, effective exercise and sound nutrition. We recommend basing your diet on lean proteins, garden vegetables (especially greens), nuts and seeds, some fruit, little starch, and no sugar. Many have observed that keeping your grocery cart to the perimeter of the grocery store while avoiding the aisles is a great way to protect your health. Food is perishable. The stuff with long shelf life is all suspect. If you follow these simple guidelines, you will benefit from nearly all that can be achieved through nutrition.
