Zinc is useful in diarrhea

According to the World Health Organization, diarrhea kills about 1.6 million children under 5 every year. An article in Time magazine said that ‘Zinc pills appear to halt diarrhea in its tracks’

In addition, a PLoS Medicine study confirmed that a 10-day course of zinc tablets is effective in treating childhood diarrhea and also helps prevent future bouts of the condition. This was seen when a nationwide public health campaign to increase zinc use for childhood diarrhea in Bangladesh was conducted.

Experts believe that about 2 billion worldwide have diets that are zinc deficient.
