THURSDAY, April 21 (HealthDay News) -- Just like eye color or blood type, the bacteria that flourish in the gut can also be used to categorize humans, new research finds.
European researchers have determined that there are three distinct types of microscopicecosystems that exist in the human intestine. What differentiates each type is which species of microbes are present and which are the most abundant, researchers said.
Although there's far more to learn about what those microbes do, researchers say yourbacterial type may tell a whole lot about you, including how you metabolize food, how you synthesize vitamins and how you might respond to certain medications.
