Scientists are creating a “super potato”, fortified with iron and zinc, in a bid to tackle malnutrition in developing countries.

Millions of people around the world suffer micronutrient deficiencies – a lack of essential vitamins and minerals. This can lead to stunting in children, who then go on to suffer cognitive delays, weakened immunity and disease. Pregnant women who lack micronutrients are more likely to have babies with defects or low birthweight.

Potato is a staple crop in many parts of the world and researchers at the International Potato Centre (CIP) in Peru believe that a biofortified variety could have an important role to play in improving diets.

After rice and maize potato is the third most consumed food in the world so increasing its micronutrient content would make a significant difference to people’s health around the globe, said Dr Oscar Ortiz, director of the CIP.
