The Claim
Daily zinc supplementation of 10 mg for 7 months reduces the incidence of diarrhea by 22% in rural Guatemalan infants aged 6–9 months, with larger reductions of 39% observed in boys and children with baseline weight-for-length below the sample median.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In rural Guatemalan infants aged 6 to 9 months, taking 10 mg of zinc daily for 7 months lowers the number of diarrhea cases by 22%, with a 39% reduction in boys and infants with lower weight-for-length measurements.
See the scientific wording
Daily zinc supplementation of 10 mg for 7 months reduces the incidence of diarrhea by 22% in rural Guatemalan infants aged 6–9 months, with larger reductions of 39% observed in boys and children with baseline weight-for-length below the sample median, suggesting zinc status may be a modifiable factor in reducing diarrheal burden in malnourished populations.
Zinc strengthens the lining of the gut and helps immune cells in the intestine fight off germs that cause diarrhea, especially when the child is undernourished.
What the research says
1 studyGiving babies in Guatemala a daily zinc pill for seven months made them sick with diarrhea less often, especially boys and babies who were already underweight. This means zinc might help protect hungry or small babies from getting sick.
