I've read so many of these claims, about so many food and drug products. They *always* turn out to be false. Always, not some of the time. Remember when butter would kill you? Then it was nature's wonder food. Remember when salt gave you heart attacks. Now it is harmless --eat as much as you want. Remember when milk was the best source of nourishment on earth? Then milk was said to be bad for adults, because their bodies are not adapted to process it. Change, change, change. The only constant in these product claims is that that are invariably disproven if you wait a year or two.
