I’ve been eating yogurt ever since I was in college. It’s yummy, friendly to your digestion and the perfect thing for a quick breakfast or snack. And it’s cheap. (Who has money in college?)

Later, I learned that I was smarter than I thought.

Because yogurt contains probiotics — “good guys” or friendly bacteria — chasing away the “bad guys” — or damaging bacteria from your digestive system.

So, probiotics are known to promote a healthy gut, but can they promote a healthy mind?
