The Science of Nutrition

The percentage of consumers (your clients) who actively seek information about nutrition and healthful eating has more than doubled from 19% in 2000 to 46% in 2011. It is important for health-fitness professionals to be properly qualified and guided to join the fight against obesity with science-based information and counsel for clients following the Academy of Nutrition and Dietetics (AND) guidelines.

The AASDN creates a fundamental understanding of science-based nutrition concepts in this course. The goal is to allow you to be able to better separate the science-based food and nutrition information from the plethora of misinformation, to properly advise and communicate about nutrition with your clients.
