Gut health is very important.

Our digestive system is not just responsible for breaking down food and absorbing the nutrients that support our bodily functions, but is also home to trillions of “good” and “bad” bacteria collectively known as the gut microbiome.

This microbiome plays several key roles, according to Singapore-based gastroenterologist Dr Andrea Rajnakova.

It directly defends against pathogens and helps maintain our intestinal lining. It also prompts antibody production to support our immune system, produces K and B vitamins including biotin and folate, and helps with weight regulation and communication between the gut and the brain.

Good gut health is achieved when there is a balance between good and bad bacteria. There are several factors that may upset this balance, including environmental factors, antibiotic use, and consuming sugary soft drinks and high-fat, processed and fast foods.
