Fateful fluoride?.
In "Zinc boosts kids' learning" (SN: 4/30/05,p. 286), I wonder if the enhanced learning that the researchers observed might have resulted not from the supplemental zinc per se, but from the zinc's blocking absorption of fluoride fluoride, a salt of hydrofluoric acid; see hydrogen fluoride. See also fluoridation; fluorine. in the juice. Most juice, especially grape and citrus, has enormous concentrations of fluoride from the pesticides used to produce it. Fluoride is known to cross the blood-brain barrier blood-brain barrier
