Bad Combination
Natural-foods cooks have long scorned aluminum utensils, saying that the metal binds with certain minerals—such as phosphorus and calcium—and robs foods of nutritive value. Recent evidence linking aluminum with Alzheimer's disease and other neurological disorders has added to their case, particularly in light of studies proving that aluminum compounds can be released from pots and pans during cooking. Now more fuel has been added to the fire: Experiments indicate that the leaching process is "dramatically enhanced" by water containing fluo-ride, at levels normally used in municipal fluoridation. In a letter published in Nature magazine, scientists report that water containing one pan per million (ppm) of fluoride frees nearly 200 ppm of aluminum when boiled 10 minutes in aluminum utensils— that's 1,000 times the amount of aluminum released in nonfluoridated water. Prolonged boiling raises aluminum concentrations even higher, to about 600 ppm.
