The foods we eat don’t just impact our individual health; they have far-reaching consequences for the planet. Now, researchers are turning their attention to how dietary patterns during pregnancy can affect both maternal and child health, while also minimizing environmental impact. A growing body of research focuses on the Planetary Health Diet – a dietary pattern designed to be both nutritionally adequate and sustainable – and its potential benefits for expectant mothers and their babies.
Traditionally, prenatal nutrition has centered on ensuring adequate intake of folate, iron, calcium and other nutrients crucial for fetal development. However, a new perspective is emerging, one that considers the broader ecological footprint of food choices. The Planetary Health Diet, initially proposed by the EAT-Lancet Commission in 2019, emphasizes a largely plant-based diet, with moderate amounts of animal products, whole grains, fruits, and vegetables. It aims to reduce greenhouse gas emissions, land use, and water consumption associated with food production.
Exploring the Impact on Pregnancy
Researchers at the University of São Paulo in Brazil are currently investigating the effects of adhering to a Planetary Health Diet during pregnancy. Their operate, recently highlighted by Medical Xpress, involves following a cohort of pregnant women and assessing various health outcomes for both mother and child. The study aims to determine if this dietary approach can improve maternal health indicators, such as gestational diabetes risk and blood pressure, and positively influence infant birth weight and development.
“We are looking at a range of outcomes, from maternal micronutrient status to infant neurodevelopment,” explains Dr. Amanda de Souza, lead researcher on the project. “The goal is to understand if a Planetary Health Diet can provide all the necessary nutrients for a healthy pregnancy while also contributing to a more sustainable food system.” The research team is also examining the feasibility and acceptability of adopting such a diet among pregnant women from diverse socioeconomic backgrounds.
Nutritional Considerations and Potential Challenges
While the Planetary Health Diet offers a promising framework, implementing it during pregnancy requires careful consideration. Ensuring adequate intake of certain nutrients, particularly iron, vitamin B12, and omega-3 fatty acids, can be challenging on a predominantly plant-based diet. The National Institutes of Health provides detailed information on recommended daily intakes of these and other essential nutrients during pregnancy.
Supplementation may be necessary to address potential deficiencies, and personalized dietary guidance from a registered dietitian is crucial. Access to affordable and diverse plant-based foods can be a barrier for some populations. The researchers in Brazil are actively addressing these challenges by developing culturally appropriate dietary recommendations and exploring strategies to improve food access.
Beyond Individual Health: Environmental Benefits
The benefits of a Planetary Health Diet extend beyond individual health. Food production is a significant contributor to greenhouse gas emissions, accounting for roughly 26 percent of global emissions, according to the Environmental Protection Agency. Animal agriculture, in particular, has a substantial environmental footprint due to land use, water consumption, and methane emissions.
By shifting towards more plant-based diets, we can reduce these environmental impacts and promote more sustainable food systems. This is especially important for future generations, who will face the consequences of climate change and resource depletion. The research on Planetary Health Diets during pregnancy represents a step towards creating a healthier and more sustainable future for both people and the planet.
Stakeholders and Future Directions
This research impacts a wide range of stakeholders, including pregnant women, healthcare providers, policymakers, and environmental advocates. The findings could inform dietary guidelines for pregnant women, promote sustainable food production practices, and raise awareness about the interconnectedness of human and planetary health.
The University of São Paulo team plans to continue monitoring the health of the mothers and children enrolled in their study for several years to assess the long-term effects of the Planetary Health Diet. They also hope to expand their research to include other populations and explore the potential benefits of this dietary approach for other life stages. Further research is needed to refine dietary recommendations and address potential challenges related to nutrient adequacy and food access.

The ongoing investigation into the Planetary Health Diet during pregnancy offers a compelling example of how dietary choices can contribute to both individual well-being and environmental sustainability. Researchers will present updated findings at the International Society for Maternal Fetal & Neonatal Medicine conference in February 2025.
