the claim that taking zinc can help you beat the common cold. Have a look:Anahad O’Connor of The New York Times investigates
One of the most extensive studies appeared in the journal Clinical and Infectious Diseases in 2000. In it, scientists randomly assigned more than 500 people — about half with natural colds, and the other half deliberately infected — to receive placebo or zinc lozenges in various doses. After secluding the subjects in hotel rooms and examining them for five days, the researchers concluded that zinc gluconate lozenges produced “modest” benefit, while zinc acetate lozenges did nothing.For advice on how to prevent the sniffles, check out DiseaseProof’s Cold and Flu category.
Another study, published this year by researchers at Stanford Medical School, collected and analyzed data from 14 previous placebo-controlled studies of zinc. Over all, the scientists determined, the effectiveness of zinc lozenges “has yet to be established,” while there was some slight evidence for zinc nasal gels.
