The report, entitled “Preventing nutrient loss and waste across the food system: Policy actions for high-quality diets”, concludes that regularly eating poor-quality food has become a greater public health threat than malaria, tuberculosis or measles.
Meanwhile, approximately one-third of food produced for human consumption never reaches the consumer’s plate or bowl. Nutrient-rich foods, such as fruits, vegetables, seafood, and meats are highly perishable, rendering them susceptible to losses throughout increasingly complex food production systems.
According to the report, each year more than half of all globally-produced fruits and vegetables are lost or wasted. Moreover, around 25 percent of all meat produced, equivalent to 75 million cows, goes uneaten.
Reducing food loss and waste, particularly high-nutrient foods, not only has nutritional benefits, but also contributes to the Sustainable Development Goals (SDGs), and should be a new priority for improving nutrition.
To remedy this the report proposes a series of policy actions across the entire food system, including educating all concerned; focusing on perishable foods; improving public and private infrastructure; and closing data gaps on food losses and waste.
FAO data indicates that in low-income countries, food is mostly lost during harvesting, storage, processing, and transportation; while in high-income nations, the problem lies in retail and consumer level waste. Together, they directly impact the number of calories and nutrients actually available for consumption.
Given the direct impact on wellbeing, learning capacity and productivity, the loss and waste of micronutrients are of particular concern.
Globally, agriculture produces 22 percent more vitamin A than we require. However, after loss and waste, the amount available for human consumption is 11 percent less than required. Reducing the loss and waste of nutritious foods could, therefore, yield substantial health benefits.
With the value of global food lost or wasted annually, estimated to be around $1 trillion, cutting down on waste would also yield major economic benefits. Additionally, eating more of the food already produced, would avoid wasting the water, land, and energy that went into its production, said FAO.
