Meat and dairy aren’t essential for a child’s development

Babies born into vegan or vegetarian families may experience slight underweight in early infancy, but research suggests they catch up to their omnivore counterparts by the age of 2.
Official recommendations affirm that a well-planned vegan diet, rich in vegetables, legumes, whole grains, and fortified foods, can offer all necessary nutrients for optimal health. However, meeting a child’s nutritional needs on a vegan diet can be challenging, with concerns about amino acid and protein deficiencies.
Recent research led by Kerem Avital at Ben-Gurion University of the Negev in Israel analyzed data from 1.2 million babies in Israel, tracking their growth patterns from birth to 24 months based on their parents’ reported diet preferences at 6 months of age. While the majority followed an omnivorous diet, a small percentage identified as vegetarian or vegan households.
Despite the lower number of vegetarian and vegan families, the study yielded significant results due to its large sample size. According to Tomer Avnon from Tel Aviv University, who was not part of the study, the findings provide reliable insights into children’s growth based on their parents’ dietary choices.
During the initial 60 days of life, infants across all diet groups showed similar length, head circumference, and growth rates. However, babies from meat-free households, especially vegans, exhibited slightly higher chances of being underweight. Conversely, overweight cases were less common in vegetarian and vegan families.
By age 2, these differences in growth metrics had largely normalized, with no significant variations among the three diet groups. Although restricted growth was slightly more prevalent in toddlers from vegetarian and vegan backgrounds, the differences were minimal and not statistically significant after adjusting for influencing factors like income and maternal age.
These findings offer reassurance that children raised by vegetarian and vegan parents can achieve healthy developmental outcomes, a sentiment echoed by Avnon. However, it’s important to note that the study relied on self-reported dietary information, potentially impacting result accuracy. Avnon highlights the need for precise nutritional assessments in early childhood to ensure long-term development.
Zulfiqar Bhutta from the Hospital for Sick Children in Toronto raises concerns about the long-term implications of the slight growth differences observed among the diet groups. Given evidence linking vegan diets to lower bone density and micronutrient levels, Bhutta advises caution in promoting vegan and vegetarian diets in regions where malnutrition is prevalent.
While the study focused on Israel, Avital suggests its findings are applicable to countries with similar economic conditions and healthcare access, such as the UK. Bhutta calls for larger studies that capture detailed dietary information and parental characteristics to enhance understanding of the impact of vegan and vegetarian diets on child growth.
