Shifting to sustainable food systems that provide affordable, diverse and plant-rich diets with moderate quantities of GHG-intensive animal protein can bring health co-benefits and substantially reduce GHG emissions, especially in high income countries and where ill health related to overconsumption of animal-based products is prevalent  . Transforming the food system by limiting the demand for GHG-intensive animal foods, reducing food over-consumption and transitioning to nutritious, plant-rich diets can have significant co-benefits to health  . Reduction of red meat consumption reduces the risk of cardiovascular disease  and colorectal cancer; the consumption of more fruits and vegetables can reduce the risk of CVD, type II diabetes, cancer and all causes of mortality . Globally, it is estimated that transitioning to more plant-based diets-in line with World Health Organization  recommendations on healthy eating-could reduce global mortality by 6-10% and food-related GHG emissions by 29-70% by 2050 . There are limitations in accessibility of affordable of healthy and diverse diets for all  and trade-offs such as the potential increase of GHG emissions from producing healthy and diverse diets in low- and medium-income countries . Agroecological approaches have mitigation and adaptation potential and deliver ecosystem services, biodiversity, livelihoods and benefits to nutrition, health and equity .
