'Power Foods' and 'Meatless Mondays'

What does it mean to “eat the rainbow”? Why do nutritionists crusade for eating more fiber? We speak to Lynda McIntyre, a clinical dietitian specialist with Johns Hopkins Medicine and a nutrition cancer specialist at Sibley Hospital in Washington, about the power of diet in achieving good health. She’ll be discussing "Power Foods" and "Meatless Mondays" at the Johns Hopkins' annual Woman’s Journey conference next week.
