Swiss food giant Nestle made misleading claims about the health benefits of some children's beverages, U.S. regulators said in letters released on Tuesday.

The Food and Drug Administration, in a December 4 letter, said Nestle made unauthorized nutrient content claims on certain Juicy Juice products marketed for children under age 2.

In a separate December 3 letter, the FDA said Nestle's Boost Kid Essentials Nutritionally Complete Drink, in vanilla, chocolate and strawberry flavors, was promoted as a "medical food" but did not meet requirements for that type of claim.

The FDA posted the letters on its Web site.
