The Contribution of Potatoes to Global Food Security, Nutrition and Healthy Diets

Abstract

Potatoes play an important role developing countries’ food security; 50% of the world’s food energy needs are supplied by potatoes, rice, wheat and maize. Developing countries’ share of global potato output now surpasses that of developed countries. Global potato consumption was on average 35 kg/capita/yr. in 2013, with large regional differences. Trends in potato consumption show that while in Europe potato consumption has been steadily decreasing, Africa and Asia have seen a ~70% increase between 1961 and 2013. Potato biodiversity is vast; variety is one of the main factors governing nutrient content. Potatoes are fat free, a source of vitamin C and vitamin B6, and can also supply good amounts of other micronutrients and fiber. Potatoes feature in the food-based dietary guidelines (FBDGs) of many countries. Some FBDGs make a distinction, recommending consumption of healthy preparations while limiting that of unhealthy forms high in energy, salt and fat.
