In plain English

Giving extra food to pregnant women in developing countries helps babies be born slightly heavier and longer. Even though the increase is small, it's a consistent and positive improvement for newborn health.

See the scientific wording

Prenatal food distribution programs in low- and middle-income countries are likely to increase mean infant birth weight by 46 grams (mean difference 46.00g, 95% CI 45.10–46.90) and birth length by 0.20 centimeters (mean difference 0.20cm, 95% CI 0.20–0.20), based on three trials involving 5,272 participants. While the absolute increases are modest, they represent consistent, statistically significant improvements in neonatal anthropometry across diverse community settings.
