Annually observed from September 1 to 7, National Nutrition Week (NNW) is a week-long initiative aiming to impart knowledge about the significance of nutrition and encourage healthier lifestyles.

In India, the National Institute of Public Cooperation and Child Development (NIPCCD) has been commemorating NNW since 1982. The event concentrates on enhancing nutritional literacy, ensuring access to well-balanced diets, and addressing health disparities associated with malnutrition.
