Armchair epidemiologist and mixed martial arts fighter Diego Sanchez, says he lost a March 15 fight at UFC 171 in Dallas because of the food he ate the night before.

“I wasn’t myself last night,” Sanchez wrote on Twitter. “I sustained food poisoning from eating a beef tartar with raw quail egg as an appetizer at dinner. This was my own mistake. I ordered it thinking I need red meat but raw was the wrong choice. I threw up first at 2 am and all day fight day.”
