Presented by Dilogen de Alwis, Retired Ophthalmologist who is now practising as a Nutrition, Health and Wellness Coach.

A human being is not just a single organism but a combined ecosystem of trillions of

health. We will examine its origins, our co-evolution, the gut microbiome in particular and its crucial
effects on human health and the measures we can take to improve our well-being.
