We have more than enough calories, but what about other nutrients?
The United Nation's second Sustainable Development Goal targets the end of malnutrition in all forms by 2030. But new research shows that to meet this target, we need a different approach to assessing the nutrient sufficiency of the global food system. Published in Frontiers in Sustainable Food Systems, this is the first study to quantitatively map the flow of energy, protein, fat, essential amino acids and micronutrients from 'field-to-fork' at a global level and identify hotspots where nutrients are lost. The study shows that while we produce far more nutrients than is required for the global population, inefficiencies in the supply chain leave many people nutrient deficient. The research highlights the complexities that arise in delivering a balanced food system, which can only be handled by a holistic approach.
