An MIT team set out to study the effects of a high-fat, low-fiber diet in mice that also ate yogurt. You know, basically “Can probiotic supplements help overcome a crappy diet?”
What they found surprised them. Mice that ate yogurt were shiny, and had thick, dense, healthy hair, like John Travolta in Saturday Night Fever. The males also, well … I don’t know exactly how to say this … they walked with a certain “swagger”.
That’s because the testicles of the yogurt-eating males were 15% larger than the junk food mice. Not only were they bigger, but they produced more pups when they mated with females. Females weren’t left out, though. Yogurt-eaters gave birth to healthier, bigger litters.
Surely you’re thinking “So, Biology Man, if I eat yogurt by the wheelbarrow-full, will I turn into Don Juan of the breakfast buffet?” Well, we don’t know how dietary observations like this translate to humans quite yet. But probiotic foods like yogurt likely create a healthier microbiome in the mouse gut, leading to less inflammation and a stronger immune system. All of that leads to a healthier, more virile mouse.
Hey, it’s good for ya. Couldn’t hurt.
