Nutrition Across the Lifespan examines the changing nutritional needs of individuals as they progress through the stages of life, from infancy and childhood through adolescence, adulthood, and into old age. The course explores the physiological, psychological, and social factors that influence dietary requirements at each stage, as well as how proper nutrition can promote health, prevent disease, and support optimal growth and development.
