title: Estimated fluoride intake of 6-month-old infants in four dietary regions of the United States.
abstract: Eleven composite food groups comprising the infant "market basket" food collections for 1977 or 1978 from each of four dietary regions of the United States were analyzed for their fluoride content. Based upon the determined fluoride content of each composite and Food and Drug Administration estimates of food consumption the daily fluoride intake of an average 6-month-old infant residing in each of the dietary regions was calculated. The daily fluoride intake varied from 0.207 mg/day in Grand Rapids, Mich. (north central dietary region) to 0.541 mg/day in Orlando, Fla. (south dietary region). Flouride intakes of 0.272 and 0.354 mg/day were calculated for Philadelphia, Pa. (northeast dietary region) and Los Angeles, Calif. (west dietary region), respectively. The fluoride content of the water supplies ranged from 0.37 ppm (Los Angeles) to 1.04 ppm (Grand Rapids). Drinking water, dairy products and substitutes (other than milk), and grain and cereal products contributed 44 to 80% of the daily fluoride intake. In three of the four dietary regions the daily fluoride intake was less than the optimum level of 0.05 mg/kg body weight.
