What's on your plate may shape your personality, according to scientists from Texas A&M University. Researchers report a variety of distinct bacteria and metabolomes in your gut actually have a connection to different personality traits.

"This reinforces many of the public health concepts related to nutrition and health," says co-researcher Matthew Lee Smith, associate professor in the Department of Environmental and Occupational Health, in a statement. "Gut microbiome may be influencing the way you are, not just the way you are today. These findings are more suggestive than definitive, but they have contributed to our understanding of what gut health can do and how it makes people feel."
