Scientists just discovered what coffee really does to your gut and brain
来源: All Top News -- ScienceDaily · 发布于
A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also producing measurable changes in gut bacteria and metabolites.
