Microbiome Quiz

Most of us grew up hearing that “you are what you eat.” But science now shows something even more fascinating – you are what your microbes eat!

Inside every stomach lives a whole world of helpful bacteria working hard to keep us healthy, happy, and full of energy. And in Vegemi’s world, some of these friendly microbes have names – one being Vegemi himself!

Vegemi is a curious little stomach bacteria who helps children (and families) understand how the foods we eat shape our microbiome — and how this invisible world connects to mood, immunity, focus, and well-being. At Vegemi, we turn the science of the gut into playful learning – helping families build healthier habits from the inside out.

Take our microbiome quiz below to learn more about this hidden but important world within us all! The multiple choice questions can have one or more correct answers! Find the answers afterwards, below.
