Eggs for Nutritional Support

Research suggests that eggs, as part of a broader category of animal-source foods, may offer meaningful nutritional support across several vulnerable populations, including pregnant women, children with cancer, and young children in low-resource settings. Studies indicate that eggs are frequently identified alongside other protein-rich foods as nutrients at risk of being inadequately consumed during pregnancy, illness, or food insecurity, with one large Japanese cohort study finding that avoiding multiple protein-rich foods including eggs during pregnancy was associated with nearly three times the odds of cleft lip or palate in offspring. A review spanning low-, middle-, and high-income countries and a Tanzanian pediatric oncology study further support the view that eggs and similar animal-source foods are particularly important for children and other nutritionally vulnerable groups who may otherwise rely heavily on starchy, lower-protein diets. The body of evidence here is largely observational — including surveys, cohort studies, and narrative reviews rather than randomized controlled trials — which limits the ability to draw firm causal conclusions, and most findings arise as secondary observations about dietary patterns rather than direct investigations of eggs in isolation, so readers should interpret the findings with that context in mind.
