Did you know your body is home to 100 trillion microbes whose population is largely shaped by what you eat and drink? If you’d like to improve your digestion, energy and mood, then meet your “gut microbiome” (the microbes and their genes that are living in your digestive tract). Like a city zoo, your large intestine houses roughly 1,000 different species, including bacteria, yeast, protozoa, viruses and worms. Your job is to cultivate a congenial clan that will support your health instead of erode it!
