Federal health officials are launching "Operation Stork Speed" to review the ingredients in infant formula, the first deep look since 1998. About three-quarters of U.S. infants consume formula, with 40% relying on it as their only source of nutrition. The FDA will assess nutrients, contaminants, and international comparisons, with a deadline for comments set for September 11. The review aims to align regulations with the latest scientific data on infant nutrition and may lead to changes in ingredients like iron levels and added sugars. The process is expected to take at least a year and involve input from various stakeholders.
