Vegetarian and Vegan Diets Don’t Hinder Infant Growth, Large Israeli Study Finds

A comprehensive new study of nearly 1.2 million infants has found that babies raised on vegetarian or vegan diets develop at the same rate as those who consume meat, offering reassurance to parents choosing plant-based nutrition for their children. The research, led by Ben-Gurion University of the Negev (BGU) and the Israeli Ministry of Health, tracked infant development over the first two years of life.

Study Details and Findings

Researchers analyzed data collected between 2014 and 2023, focusing on weight, height, and head circumference measurements. The study encompassed approximately 70% of all infants in Israel, leveraging the country’s widespread use of preventative healthcare checkups at “Tipat Halav” baby wellness centers.

The infants were divided into three groups: those from omnivorous, vegetarian, and vegan households. The study defined family dietary habits as applying to the infant, assuming parents’ eating choices extend to their children. [Source: The Times of Israel]

Results showed that babies from vegan families exhibited growth trajectories nearly identical to those from omnivorous families. While vegan infants were slightly more likely to be underweight in the initial weeks, this difference diminished over time and was no longer statistically significant by age two. Growth delays were rare and did not vary significantly between the groups. [Source: Ben-Gurion University]

Importance of Planning and Maternal Nutrition

Researchers attribute the initial weight differences observed in vegan infants, in part, to the lower body weight of vegan mothers. They emphasize the critical importance of well-planned diets, ideally with nutritional guidance during pregnancy and breastfeeding. [Source: The Times of Israel]

Reassuring Findings for Plant-Based Families

“In the context of developed countries, these findings are highly reassuring,” said Kerem Avital, a clinical dietitian and doctoral student at Ben-Gurion University of the Negev. “The data suggest that with the proper environment, plant-based diets do not compromise the fundamental physical development of infants.” [Source: The Times of Israel]

The study likewise challenges the common belief that meat is essential for healthy infant growth. Researchers found that plant-based sources, such as legumes, nuts, seeds, and tofu, can adequately provide the necessary iron for infants when incorporated into a balanced diet.
