The Romans called bacon "Petaso".
Petaso was an early form of cured pork which was boiled with figs and spices before it was grilled and served as a staple food for soldiers and common people alike.
Like modern bacon, the petaso bacon was a salt cured pork product that was essential for preservation before refrigeration was common.
Petaso was often prepared by boiling it with figs, then browning it and seasoning it with pepper sauce.
Pork was also abundant in the diet of Romans and petaso was used as a practical food source for both everyday sustenance and military campaigns.
The one food that the ancient Romans never ate were tomatoes as well as potatoes as tomatoes and potatoes originated in the Americas and were only introduced to Europe after the Roman Empire's fall.
Other ingredients that were not known to the Romans were sugar, eggplant, bell peppers, rice and spinach.
Romans also did not eat dog meat, as Romans actually valued dogs as their guards, hunting partners and companions.
Dog meat was rarely considered food to Romans, although there may have been a few rare cases where some Romans have eaten dog meat out of necessity but it was not common.
Romans would eat human meat sometimes through medicinal cannibalism.
When Romans ate human meat through medicinal cannibalism, they did so for eating the body parts and blood for healing purposes.
In extreme circumstances, Romans would also sometimes eat human meat through survival cannibalism such as during sieges, although it was often viewed with horror and sometimes would be used as a smear tactic against enemies.
Also Ancient Roman authors also documented such practices of eating human meat, with Pliny the Elder detailing the medicinal uses for human organs and blood.
Romans who were influences by Greek texts, used various different human body parts, which included the brain, bone marrow and blood for medicinal purposes.
And fresh human blood, especially from wounded gladiators was also believed to cure ailments such as epilepsy.
Medical vampirism is also a term that describes the practice of consuming of human blood for it's purported healing properties.
And instances of cannibalism during Roman times occurred during sieges, like the siege of Numantia in 134 BCE and the First Mithridatic War at Athens, when people resorted to eating of human bodies to survive starvation.
