May as well be touting the value of wheat.
WHEAT: One of the pillars of all post-nomadic civilization.
Nomads are cool and tall and muscular. City-dwellers are short and flabby.
Humans were shorter in the past. Five to ten inches shorter in the mid 1800's, when the first records of it were taken. You can only imagine how it was back in the days of nomads. Muscular is doubtful too. Limited diet, common disease...
If you want tall and muscular humans, you are only going to find them in the modern day.
Actually the barbarians on the frontiers of Rome and Greece were known for tallness and muscularity. Celts like
Hochdorf Man in 500 BC were 6'2" tall. Their diets have been described as mostly pastural, diary and meat, meanwhile most Greeks and Romans subsisted on bread and other agrarian offerings, which are lower in protein.
There have also been other burial mounds from Northern Italy and Ireland showing the tallness of Celtic nobility. However, the size of ordinary Celts with less ample diets is hard to determine, since their burials are rarely recovered. The Greek and Roman literature stereotypes all barbarians as quite tall, though.
In general, nothing about modern man is better than ancient man. Same gene pool, really. Their capacity for height, or muscularity, or for intellect is equal to ours. The only difference is better average nutrition, and even that is just on average.
My favorite fruit is milk.
