Forget everything you know about "eating healthy", and everything you think you know about it.

Simplest Rule of Good Nutrition Ever: EAT REAL FOOD.
Real Food = Meat (poultry, beef, seafood, pork, game, fowl, etc.), eggs, vegetables, fruit, nuts, and seeds. If Mother Nature didn't create it, you probably shouldn't be eating it.
