    For decades, scientists have speculated that "gut microbes influence our eating habits", but this conjecture has not yet been tested in animals larger than fruit flies


    Dietary choice is a fundamental aspect of animal behavior, with ecological and evolutionary implications


    Specifically, the researchers found that herbivorous mice voluntarily chose foods with higher protein:carbohydrate (P:C) ratios, while omnivorous and carnivorous mice chose foods with lower P:C ratios

    To further investigate whether microbes could influence the host's dietary preferences to test the hypothesis, the researchers selected 30 germ-free mice and divided them into three groups


    Tryptophan may be the main substance that affects the host's foraging behavior
