Experts from the EAT Foundation (Springmann et al) analysed the health and environmental implications of adhering to national food based dietary guidelines (FBDG) from 85 countries and compared these with global health and environmental targets. They concluded that national guidelines could be both healthier and more sustainable if they were closer to the EAT Planetary Health diet which is a predominantely plant-based diet.
The EAT Foundation is calling national health authorities to update their national dietary guidelines taking health and environmental benfits into account. Limiting the consumption of animal-derived foods, in particular beef and dairy, has the greatest potential for increasing the environmental sustainability of dietary guidelines. Increasing the intake of whole grains, fruits, vegetables, nuts, seeds, and legumes, while reducing the intake of red and processed meat, and attaining balanced energy intake were associated with most of the health benefits
