Beans and peas have emerged as the top choice for replacing meat and milk in diets, according to a recent study conducted by researchers at UCL and the University of Oxford. Published in the Proceedings of the National Academy of Sciences, the study compared various meat and milk alternatives, including legumes, processed products like veggie burgers and plant milks, and even prospective options like lab-grown meat.

The results of the study highlighted that unprocessed plant-based foods such as soybeans, peas, and beans offer the best nutritional, health, environmental, and cost benefits when compared to traditional meat and dairy products. By opting for legumes over meat and milk, individuals can reduce nutritional imbalances in high-income countries like the U.K., U.S., and Europe by half and decrease mortality rates from diet-related diseases by a tenth.

Dr. Marco Springmann, the lead researcher of the study, emphasized the importance of reducing meat and dairy consumption in affluent nations to combat climate change, biodiversity loss, and improve overall health. While processed plant-based foods like veggie burgers and plant milks also showed benefits in replacing meat and dairy, they fell short compared to unprocessed legumes in terms of emissions reductions, health improvements, and costs.

Surprisingly, tempeh, a traditional Indonesian food made from fermented soybeans, emerged as a strong contender due to its nutritional properties, minimal processing, and affordability. In contrast, lab-grown meat was found to be the least favorable option, with high emissions, costs, and health impacts compared to conventional meat products.

Although advancements in technology could potentially reduce the costs and emissions associated with lab-grown meat, the study suggests that existing alternatives like legumes are readily available and affordable without the need for new technologies. Dr. Springmann emphasized the importance of implementing public policies that support healthy and sustainable dietary choices for all individuals.

In conclusion, the study provides valuable insights into the benefits of incorporating legumes and unprocessed plant-based foods into diets as a sustainable and cost-effective alternative to meat and dairy products. By making informed choices, individuals can contribute to environmental conservation, improve their health, and reduce the burden of diet-related diseases.
