Abstract
In the past decade, micronutrient malnutrition has been identified as a major underlying cause of numerous human health problems in developing countries. The international agricultural research system has been highly successful in producing crop varieties with traits desired by farmers, such as higher yield and greater tolerance of poor growing conditions. These improved varieties have spread widely throughout developing countries and now provide the staple foods eaten daily by billions of people, including the poor in many difficult to reach rural areas. Modern plant breeding and biotechnology offer new opportunities to use this same international system to increase the micronutrient content and enhance the nutritional value of these staple foods. Over time, this could be an important complement to the progress that is being made in providing micronutrient supplements and fortified foods and in encouraging people to eat more diversified diets. Nutritionists and agriculturists will need to work together to define the deficiencies, target the right populations and deliver the right products.
