An overview of
ION courses
Nutrition courses for you, your life and your career
If you have ever asked yourself: “What should I eat to be healthy?”, then you are not alone. With so much mixed messaging around what is or isn’t meant to be good for us, no wonder there is so much confusion about food. Should we eat fat? Should we eat gluten? Is sugar bad?
We all have to eat, but how do we sort out the fact from fiction?
What research increasingly reveals, however, is that one size does not fit all. We all have our own microbiome (ecosystem of gut bacteria), genetics and DNA, health journey and lifestyle. Even identical twins can respond differently to the same food!
