Gladiators and meat eating

Often in a talk on vegetarianism many allies cite the example of experience of ancestors, they say "they ate meat". Also in consciousness of many peoplethere is a stereotype about influence of lack of carrion in a diet on a physical force and on the level of the aggression necessary for Fight. At the same time, they probably don't know that till the 20th century meat was quite rare product on tables of simple people which actually and constituted the basis of any army which made feats, which went to death for freedom of the earth.
It isn't obligatory to look in history, we also have examples of our contemporaries, Dima Borovikov, Alexey Voevodin for example. Our many companions that have been arrested for active actions support vegetarianism and veganism. All this says that the refusal of eating of the killed animals doesn't influence existence of Spirit of Fight and physical force, there are many confirmations to that. However, one more nail in a coffin of stereotypes about vegetarianism is the recent research of bones of the Roman gladiators, which has proved that they didn't eat meat. Experts from department of histology and embryology of Medical university of Vienna have studied thousands of bones found on burial of gladiators near the stadium constructed at the emperor Nerona in the Turkish city Efes.
The matter is that if gladiators ate meat, the level of content of strontium and zinc in their bones would be approximately identical. However, the spectral analysis showed that strontium in bones is much bigger, than zinc as it usually happens at vegetarians. Besides, there are several sources describing a diet of the Roman gladiators from whom follows that they ate barley cakes, olive oil, cheese, garlic and nuts. By the way, vegetarianism was quite widespread in ancient art, for example, most of the Greek philosophers didn't eat meat. For example, Socrates, Platon, Diogenes, Plutarch, Hesiod.
Exception was Aristotle who denied presence of soul at animals. Approximately since the third century of our era the Christianity gains strength and becomes especially popular at the emperor Konstantin. At this time Aristotle's postulate about absence of animal's souls becomes predominating and meat-eating stops being the privilege of rich men. Derogations from canons of a christianity were cruelly punished. Thousands and thousands of heretics have died on inquisition fires from 400 to 1400 AD. And vegetarianism was considered as heresy...
And that tells us several things. That the vegetarian way of life is shrouded in fog of stereotypes and ignorances and many allies look at the companions vegetarians and at their ideas through this fog. Sometimes it happens because of insufficient knowledge on a subject, but sometimes - simple from unwillingness to think and refuse from deeply sat down representations having nothing in common with reality.
