The role of sanitation in malnutrition--a science and policy controversy in India.

Over the past decade, India's economic growth has been remarkable - yet almost half of India's children under 5 remain stunted. The National Food Security Bill is the country's response to this critical situation. Studies reveal that Indian children are chronically undernourished, not only because of lack of food but also because of recurring gastrointestinal infections. The stunting problem revolves more around lack of sanitation than food insecurity. Despite acknowledging that malnutrition is 'complex and multidimensional', government action has consisted largely of nutritional interventions and subsidized food. Although improvements in sanitation would be the most effective way to reduce excessively high levels of chronic undernutrition and stunting, a review of policy formulation and implementation reveals deficits and disconnects with available scientific evidence. It is time to change these mistaken assumptions and focus on improving access and use of safe sanitation facilities to achieve India's nutritional goals.
