Right on DR. As athletes age, their diet becomes more important to their performance. They can get away with eating crap when younger, but if they want maintain that high level, diet has to change. Example, Dave Scott, Carl Lewis, Scott Jurek. There is many more more world class vegan athletes that just don't publicize their diets. Including strength athletes and football players. Ricky Williams. Being an elite vegan athlete is still somewhat new, but it is changing very rapidly. As more and more come forward it will totally change the ridiculous food pyramid and animal products will not only be absent from it, they will be advised to avoid.
