Understanding Your Digestive System 

Constantly churning inside of you, the digestive system performs a daily marvel: it transforms your food into the vital nutrients that sustain your body and ensure your survival. This video traces food’s nine-meter-long, 40-hour journey through the remarkable digestive tract.

Hunger claws at your belly. It tugs at your intestines, which begin to writhe, aching to be fed. Being hungry generates a powerful and often unpleasant physical sensation that’s almost impossible to ignore. After you’ve reacted by gorging on your morning pancakes, you start to experience an opposing force: fullness. But how does your body actually know when you’re full?

The bacteria in our guts can break down food the body can’t digest, produce important nutrients, regulate the immune system, and protect against harmful germs. And while we can’t control all the factors that go into maintaining a healthy gut microbiome, we can manipulate the balance of our microbes by paying attention to what we eat. This video helps understand the best foods for a healthy gut.
