Several microorganisms live on or inside the human body. The highest abundance and diversity of these microorganisms are found in our gut, approximately a trillions of bacteria. These microorganisms are very closely associated with numerous aspects of normal host physiology such as nutritional status, behaviour and stress response. However, the gut microbes are also the cause of several diseases which are caused by changes in the composition of the resident microbiota. What we eat determines our microbiome composition and inturn determine their positive or negative role in our health.
Several recent research publications have shown the possible mechanism of the role of microbes in health and disease. Its the current area of research which is blooming in the field of human health.
