When it comes to your health, we’re not afraid to talk sh*t. We mean it: Studies show that how comfortably stuff comes out of your body (or doesn’t) says everything about what’s going on inside, particularly in your gut. That’s the home of trillions of healthy bacteria that, yes, help you poop, but also benefit your heart, immune system, mood, hair, skin and more. With all that hard work, your microscopic friends have gotta eat. But we don’t blame you for forgetting to feed them. You’re busy. We’ve seen your iCal.
