The fluoride content of selected foods in relation to the fluoride concentration of water.

The F content of foods and beverages comprising a substantial proportion of the Hungarian diet has been determined. Vegetables and fruits grown in three areas where the mean F content of water was 0.09 mg/l, 0.81 mg/l and 1.91 mg/l did not reflect these differences. In contrast, the F content of cooking water has made demonstrable contribution to the F content of cooked foods. Significant elevation in F concentration was also found in some meat products, where the inclusion of bone dust or fragments is suggested by corresponding increase in Ca content.
