The rapidly increasing world population and climate change have put a strain on current food systems resulting in an increase in the demand of food.  Since food systems have an impact on land degradation, loss of biodiversity, degradation of the environment and human health, studies have indicated that a change in dietary habits could improve health and environmental sustainability. The current food systems do not only negatively impact the environment, but have resulted in loss of food security, unhealthy diets causing diseases and obesity while the rest of the population struggle to access safe and nutritious food.
