"Most people think malnutrition is all about not having enough food or enough of the right kind of food to eat," but while "[t]his is a big part of the story ... there are many other links in the chain," Lawrence Haddad, director of the Institute of Development Studies, writes in a BBC Magazine opinion piece. "So dealing with malnutrition means fixing all the links in the chain -- food, health, sanitation, water and care," he states. "We know that handwashing with soap helps prevent diarrhea. We know that fortifying flour and salt with key vitamins and minerals bolsters nutrient intake for those with low quality diets. We know that deworming improves nutrient absorption by the gut," he continues.
