The microbiome refers to trillions of ‘bugs’ or microorganisms (also called microbiota or microbes) of thousands of different species.
These include not only bacteria, but also fungi, parasites, and viruses that mostly reside in the large intestine.
These microbes begin colonising the gut at birth. Later on, environmental exposures and diet can change one’s microbiome.
The microbiome consists of good and bad microbes that coexist without problems in a healthy body. Various illnesses, certain diets, or prolonged use of antibiotics, can result in dysbiosis and this increases susceptibility to diseases like obesity, metabolic disorders, cancer, etc.
Gut health has a direct impact on immune system function and therefore on overall well-being.
Dietary fibres cannot be digested and pass relatively intact through the gut, where bacteria feed on it. This produces nutrients, which include vitamins B and K, that help support our immune system.
