“It’s IN you, it’s ON you. It’s YOU!” This is the wordplay used to introduce a new four-part video series about human gut microbiota that’s just been released by the Canadian Digestive Health Foundation. This animation project pursues the goal of educating people on how to protect, enhance and improve their digestive health.
The videos invite the audience to explore the rich and diverse world within us, formed by over 100 trillion, brightly-coloured, microorganisms: the bacterial ‘superheroes’ living in our guts! We learn how these “superheroes” work to protect us, or how they may be affected by diet or probiotics.
We celebrate this new educational, easy way of learning about the essential role that the gut flora plays in our overall health.
