Nutrition is a science and an art. One of the most rewarding, and yet challenging aspects of being a dietitian involves nutrition education. I have been involved in nutrition and fitness for close to 10 years and one thing is certain: people are confused! Part of this stems from the lack of appreciation for nutrition as a science. Celebrities, internet gurus, and self-described nutrition coaches fail to appreciate that human nutrition is rooted in basic sciences like chemistry and biology.
