Diarrhea: The Great Zinc Breakthrough

Time Magazine has an article on the use of Zinc to treat diarrhea. Here's a snippet:
"Exactly how zinc stops diarrhea is not entirely clear. Olivier Fontaine, a diarrhea specialist for the WHO, believes that since the mineral is an essential ingredient in about 300 enzymes, boosting zinc levels strengthens the body's immunity, thus preventing diarrhea from turning deadly. A single course apparently also staves off further bouts of diarrhea for about three months — long enough to see a community through the deadly rainy seasons."

"Scientists first hit on zinc's effectiveness in the early 1990s, when researchers from the Johns Hopkins School of Hygiene and Public Health in Baltimore, Md., gave children in New Delhi a daily dose of syrup containing 20 mg of zinc. The rate of diarrhea dropped dramatically. "Nobody believed the results," Fontaine says. "No one had an explanation why zinc worked."

"As TIME pointed out in an international cover story three years ago, celebrities don't hold concerts for diarrhea. "Compared with malaria and AIDS, we are totally underfunded," says Fontaine. "This is truly a neglected disease."
