'D' ficient teens need more milk
Researchers in Boston have found that teens are not getting enough vitamin D from the foods they eat. In a year-long study of more than 300 healthy teen boys and girls, nearly one quarter were found to be vitamin D deficient. Since childhood and adolescence is a time when vitamin D is critical for calcium absorption and bone growth, experts recommend that attention be paid to optimizing dietary vitamin D intake during these years. In this study, nutrition assessment and lab data showed that vitamin D levels increased with increased milk consumption. Milk's impact on vitamin D levels is especially significant during the winter and spring months in northern climates when decreased exposure to sunlight slows the body's ability to produce vitamin D. (Editor's note: The number one source of vitamin D in the American diet is fortified milk.)
