The Functional Nutrition Course is an excellent course into how and why our bodies work as they do and how we can influence and improve our health and lives through diet-based choices and solutions. I would highly recommend this course to anyone wanting to improve their own health or that of family members and/or friends/work colleagues. Understanding how the immune system works and how food affects our health as well as how nutrition affects our entire body and our emotions give us all hope for long and happy lives free from illness and disease.
