The Claim

Breastfeeding reduces the measurable beneficial effects of zinc supplementation on diarrhea and growth in low birth weight infants.

Source: Impact of zinc supplementation on diarrheal morbidity and growth pattern of low birth weight infants in kolkata, India: a randomized, double-blind, placebo-controlled, community-based study.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

In low birth weight infants, breastfeeding lowers the observable benefits of zinc supplementation on reducing diarrhea and improving growth.

See the scientific wording

The beneficial effects of zinc supplementation on diarrhea and growth in low birth weight infants are substantially reduced by the protective influence of breastfeeding, suggesting that breastfeeding may mask or attenuate the measurable impact of zinc in this population.

Why this might work

Breast milk contains substances that bind to zinc and make it harder for the baby’s gut to absorb it, so even when zinc supplements are given, less of it gets into the body to help fight diarrhea or support growth.

  1. Study: Impact of zinc supplementation on diarrheal morbidity and growth pattern of low birth weight infants in kolkata, India: a randomized, double-blind, placebo-controlled, community-based study.

    In this study, babies who got zinc supplements had fewer diarrhea cases and grew better, but those who were breastfed showed less of these benefits—like breastfeeding was hiding or reducing the zinc’s positive effects.
