Your gut is at the center of your health— even Hippocrates believed so, stating,“ All disease begins in the gut.” Modern science agrees: the digestive system plays a crucial role in overall wellness.

WHAT IS GUT MICROBIOTA? Inside your gastrointestinal( GI) tract live over one hundred trillion microorganisms, collectively known as microbiota. These are tiny living things— like bacteria, viruses, and fungi— that help digest food, absorb nutrients, and support your immune system. Not all microbiota are helpful, though. When the balance tips toward unhealthy bacteria, you may experience problems ranging from bloating and gas to more serious issues like diabetes, depression, obesity, autoimmune diseases, and certain cancers.

HOW DIET SHAPES YOUR GUT

According to experts, what you eat is one of the biggest influences on your gut microbiota. Fiber-rich foods— such as whole grains, fresh fruits, vegetables, and dairy— help grow healthy bacteria and keep your bowels regular. On the other hand, eating a lot of high-fat, sugary foods and not enough fiber can reduce good bacteria and cause constipation.
