One of the deepest mysteries of the human mind is that it doesn’t feel like part of the body. Our consciousness seems to exist in an immaterial realm, distinct from the meat on our bones. We feel like the ghost, not like the machine.
This ancient paradox—it’s known as the mind-body problem—has long perplexed philosophers. It has also interested neuroscientists, who have traditionally argued that the three pounds of our brain are a sufficient explanation for the so-called soul. There is no mystery, just anatomy.
In recent years, however, a spate of research has put an interesting twist on this old conundrum. The problem is even more bewildering than we thought, for it’s not just the coiled cortex that gives rise to the mind—it’s the entire body. As the neuroscientist Antonio Damasio writes, “The mind is embodied, not just embrained.”
The latest evidence comes from a new study of probiotic bacteria, the microorganisms typically found in yogurt and dairy products. While most investigations of probiotics have focused on their gastrointestinal benefits—the bacteria reduce the symptoms of diarrhea and irritable bowel syndrome—this new research explored the effect of probiotics on the brain.
The experiment, led by Javier Bravo at University College Cork in Ireland, was straightforward. First, he fed normal lab mice a diet full of probiotics. Then, Mr. Bravo’s team tested for behavioral changes, which were significant: When probiotic-fed animals were put in stressful conditions, such as being dropped into a pool of water, they were less anxious and released less stress hormone.

There are Free Lunches: Behavioral Clues to Live Happy in the Economic World is a blog that intends to present updated and relevant information about the "hidden" and only recently uncovered dimensions of the economic science: the behavioral factors. With this blog we intend to promote in Europe and in the rest of the World, the top research articles and perspectives on behavioral economics, decision making, consumer behavior, and general behavioral science. We aim to be followed by journalists, academics, managers, civil servants, and everyone who wishes to improve their daily interaction with the economic world and consequently, their lives' happiness.
