We’re all aware of the health benefits of dietary fiber. But what is dietary fiber and how do we metabolize it? Research by U-M scientists and their colleagues has begun to uncover how our gut bacteria metabolize the complex dietary carbohydrates found in fruits and vegetables.
I am fascinated by the Human Microbiome Project and the fact that, "Trillions of bacteria live in human intestines – there are about ten times more bacterial cells in the average person’s body than human ones. Known as ‘microbiota’, these bacteria have a vital role to play in human health: they are central to our metabolism and well-being."
