Professionals often refer to the gut as the “second brain” of the body, as it has extensive influence on mental and physical well-being. But what exactly is the gut and how can its health be improved? The human body has several factors that need to be considered, including the entire gastrointestinal (GI) tract, the enteric nervous system, and the gut’s microbiome. Trillions of bacteria make up the gut’s microbiome, having a crucial impact on immunity, heart health, emotional and mental health, and maintaining a healthy weight. Improving the gut’s health involves various lifestyle factors, such as diet, exercise, medications, illnesses, and environmental toxins. Incorporating fruits, vegetables, whole grains, and fermented foods into the diet can promote digestion, support the gut microbiome, and strengthen the immune system. Engaging in regular physical activity and spending time outside are also important aspects of improving gut health. Furthermore, avoiding over-sanitizing and embracing a little dirt can expose us to important bacteria that enhance the immune system and decrease allergies and intolerances. By living a healthy and active lifestyle, focusing on fresh foods, few processed and packaged foods, and regular exercise, one can improve and maintain gut health, benefiting the body overall.
