It has been cited widely that there are ten times more bacteria in our body than human cells. However, just this month a new paper was published in Nature ( http://www.nature.com/news/scientists-bust-myth-that-our-bodies-have-more-bacteria-than-human-cells-1.19136 ) and they now claim that it’s about the same number and that “The numbers are similar enough that each defecation event may flip the ratio to favour human cells over bacteria.” According to the paper, “The 10:1 myth persisted from a 1972 estimate by microbiologist Thomas Luckey, which was ‘elegantly performed, yet was probably never meant to be widely quoted decades later’, say the paper’s authors.”
