Social entrepreneur Felix Brooks-church has been tackling one of the world’s greatest afflictions, malnutrition. A Rolex Awards Laureate, Brooks-church has developed an ingenious device to fortify flour with nutrients and also a business model that ensures there is no extra cost to consumers or millers, and the fortified flour can be sold at the same price as the unfortified product. With the creation of the “dosifier” – the groundbreaking machine delivering precisely measured doses of essential micronutrients like iron, B12 and zinc into grains during the milling process – Brooks-church is helping to eradicate malnutrition, one fortified bag of flour at a time.
