Archeologists recently unearthed a burial site in Turkey containing the bodies of 60 Roman gladiators.

Tests to their remains led researchers to conclude that the gladiators all ate an exclusively-plant-based diet.

In fact, they used the word "vegan" to describe the gladiators.

Wait, aren't vegans those guys you see carrying signs outside KFC protesting animal cruelty?

Yeah.

And gladiators ate a vegan diet, too.

In the following video John McDougall MD describes the new find on gladiators and pokes some fun at the biases of researchers -- who stretch to come up with explanations for why the most powerful fighters of the ancient world would opt to eat a vegan diet.

Of course, the gladiators weren't alone.

The entire Roman army went on a vegan diet whenever they went into battle.

This is a short excerpt from Dr. McDougall's fascinating talk entitled "THE STARCH SOLUTION" from the Healthy Lifestyle Expo 2009. Dr. McDougall shows how every major successful culture throughout history has relied on a largely starch-based diet to be successful.
