Visualizing Nutrition

Visualizing Nutrition teaches students to identify and connect the central elements of nutritional science using a visual approach.  As students explore important nutrition topics, they are immersed in content that not only provides scientific understanding, but demonstrates relevance to their personal lives. Students are challenged and taught the decision-making skills needed to navigate the countless choices they will face in promoting their good health and preventing disease. Visualizing Nutrition's critical thinking approach with a solid underpinning of the scientific process empowers students to be knowledgeable consumers when faced with decisions about what to eat.
