Infant nutritional physiological phenomena covers the unique nutrition and physical needs of infants, from birth to about two years of age. It is essential to provide infants with the adequate amount of nutrition in order to support healthy growth and development. During early infancy, the nutritional needs of infants are significantly higher than in adults and children. Adequate nutrition is also important for proper development of the immune and digestive systems, as well as for brain development. The most common nutritional sources for infants are breast milk and infant formula, both of which must meet certain nutrient standards. Proper nutrition is important in order to reduce the risks of diseases and health problems in early life and beyond.
