The Case for Biofortification

Modern consumers enjoy something that humans throughout history never have: we can walk into a grocery store and, if we choose wisely, leave with food that maximizes our health. Much maligned as the industrial food system has been, it’s made accessible a broad diversity of beneficial foods that, consumed regularly, prevent disease and enhance the quality of life. The fact that one is able to eat a cornucopia of “superfoods”–blueberries, bananas, kale, lentils, quinoa, and avocados–on a daily basis is an under-appreciated wonder of globalization and world trade.
But the vast majority of the developing world lacks access to this abundance. In fact, billions of people living in developing countries are dependent on a single staple crop for their sustenance. In sub-Saharan Africa, 250 million people eat cassava as their primary food source; over half the world depends on rice for 80% of their calories; wheat accounts for 20% of the world’s food energy intake. This narrow dependence might meet baseline caloric needs, but it’s a nutritional disaster.
How to bridge the gap between the nutritional haves and have-nots is a hotly contested issue. Some support the development of small-scale but modernized organic systems serving regional markets. Others promote replacing traditional peasant agriculture with the industrialized approach of agribusiness. Yet others would like to see local farmers empowered to practice indigenous methods. Whichever schemes ultimately prevail (hopefully a combination of all), there’s one solution that must be included irrespective of agricultural scale or scope: crops must be biofortified. That is, we need to plant seeds that have been bred to enhance nutritional value.
