Gut microbes may affect heart disease risk
But studies in rodents suggesting a link may not play out in people.
You never eat alone. Instead, you share every meal or snack with an entire community — trillions of bacteria, fungi, and other microbes that live in your digestive system. A provocative study suggests that these microorganisms may affect the development of artery-clogging atherosclerosis.
How vast is this ever-changing community of microbes? For every one of your body's cells, there are 10 microbes living in your gut and mouth, on your skin, and elsewhere. It's a cozy relationship. You give them food and a warm place to live. They return the favor by breaking down toxins, crowding out invaders, manufacturing certain vitamins and amino acids, and training your immune system.
