Linking Nutrition to Mental Health

To truly live well – to feel good, engage in productive activities, enjoy fulfilling relationships with other people, and be able to adapt to change and cope with adversity – Americans must start addressing mental health with the same urgency as physical health.

Ruth Leyse-Wallace, PhD, RD reviews scientific research from around the world and many disciplines to demonstrate how diet, vitamins and minerals, genetics, and health conditions can affect an individual’s mental well-being as much as his physical well-being.
