The Claim

Intermittent zinc supplementation in zinc-deficient infants reduces the incidence of acute respiratory infections by 72% and acute diarrhoea by 49%, while simultaneously increasing mean weight gain by 332 g and length gain by 1.4 cm over six months.

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 plain English

Giving zinc supplements at specific times to babies in poor-nutrition areas cuts their chances of getting sick with colds and diarrhea by more than half, and helps them grow taller and heavier.

See the scientific wording

Intermittent zinc supplementation in zinc-deficient infants reduces the incidence of acute respiratory infections by 72% and acute diarrhoea by 49%, while simultaneously increasing mean weight gain by 332 g and length gain by 1.4 cm over six months.

Why this might work

Zinc helps babies grow longer and heavier by improving gut nutrient absorption and speeding up cell growth in muscles, bones, and fat, while too much omega-6 compared to omega-3 keeps the body inflamed and hurts growth.
