Worldwide 250 million children suffer from vitamin A deficiency (VAD). VAD is one of the main causes for nutrition-based childhood blindness. In fact, 250,000 - 500,000 children go blind every year. 50 per cent of these children die within the next 12 months. Our vision is to tackle this problem. Our means are simple, but effective. With our specially bred sweet potatoes high in vitamin A, we want to join the fight against blindness.
