Switching from a Mediterranean-style diet to a fully vegan one can significantly reduce greenhouse gas emissions, according to a new study published in Frontiers in Nutrition. Led by Noelia Rodriguez-Martín, PhD, the research compared different meal plans and found that a vegan diet produced 46 percent less CO2, used 33 percent less land, and 7 percent less water compared to a Mediterranean diet that included meat.

The study also showed that a plant-based diet is nutritionally balanced, meeting most recommended daily nutritional requirements. While only vitamin D, iodine, and B12 needed extra attention, these nutrients can easily be supplemented or obtained from fortified foods. The research emphasizes that even small steps towards a more plant-based diet can make a significant impact on reducing emissions and saving resources, ultimately leading to a healthier planet.
