I am surprised they emphasize "development of the cognitive functions required to excel in soccer" but not physical development from meat (and hence higher protein) consumption
There are a ton of professional athletes who don't eat meat and apparently get plenty of protein.
I think you mean wealth right?
How many can you name?
Or, since that would be anecdotal: what surveys have been done of professional athletes' diets?
And if there are any, is the percentage of vegetarians higher than a comparable group in the same age bracket?
