We have probably all heard about this, but what exactly is the gut-brain axis, and what does it do? In short, it describes a newly discovered two-way functional link between the function of the gut and cognitive health.

The digestive system is like a long, one-way tube, that takes in food (stomach), removes waste (feces), and in between extracts nutrients from food (the intestine – also called the gut, or bowel).

To understand what prebiotics are, it helps to understand what dietary fiber is. Dietary fiber is a sub-category of macronutrients that helps with gut health and motility. In children, there are multiple health benefits of dietary fibre, including preventing obesity and constipation.
