Effects of couscous supplementation on breast milk production and infant weight gain: a crossover clinical trial.

TL;DR

Couscous supplementation proved to be a viable strategy for enhancing both milk production and infant weight gain in exclusively breastfed infants.

Key Findings

Infants whose mothers consumed couscous showed significantly greater daily weight gain compared to the group without supplementation.

  • Infants in the couscous group gained 33.7 g/day compared to 24.6 g/day in the group without supplementation.
  • The difference was statistically significant with P-value = .007.
  • Infant weight was measured on days 1, 20, and 40 of the study.
  • The study involved 30 breastfeeding mothers of exclusively breastfed infants.

The majority of mothers reported a marked increase in breast milk production while consuming couscous.

  • 60% of mothers reported a marked increase in milk production while consuming couscous.
  • Increase in milk production was assessed using a Likert scale.
  • The supplementation consisted of 70 g of couscous daily for 20 days.

The study used a crossover design in which participants alternated between couscous supplementation and no supplementation periods.

  • 30 breastfeeding mothers were divided into two groups.
  • One group consumed 70 g of couscous daily for 20 days, followed by a 20-day period without supplementation, while the other group followed the reverse order.
  • Couscous was described as a rich source of corn starch.
  • The total study duration per participant was 40 days.
