Plant Breeding: A New Tool for Fighting Micronutrient Malnutrition

The final permanent solution to micronutrient malnutrition in developing countries is a substantial improvement in dietary quality—higher consumption of pulses, fruits, vegetables, fish and animal products that the poor already desire but cannot presently afford. Meanwhile breeding staple foods that are dense in minerals and vitamins provides a low-cost, sustainable strategy for reducing levels of micronutrient malnutrition. Getting plants to do the work of fortification, referred to as “biofortification,” can reach relatively remote rural populations that conventional interventions are not now reaching and can even have benefits for increased agricultural productivity. Biofortification, thus, complements conventional interventions. The symposium articles discuss several examples of ongoing research projects to develop and disseminate nutrient-dense staple food crops and issues that remain to be resolved before successful implementation can be attained.
