If you ask most medical experts about the hottest trends in health research, chances are they'll mention the microbiome. The term refers to the trillions of microbes living inside our bodies, known as the human microbiota. The vast majority of these bacteria, viruses, and fungi dwell deep within our intestines. These microbes help with digestion, make certain nutrients, and release substances that have wide-ranging health effects.
"There's a complex interplay between the microbes in our intestines and most of the systems in our bodies, including the vascular, nervous, endocrine, and immune systems. All of these relationships are highly relevant to cardiovascular health," says Dr. JoAnn Manson, professor of medicine at Harvard Medical School and chief of preventive medicine at Brigham and Women's Hospital.
