Since 2008, Kathryn Dewey has coordinated a massive, international research effort called the “iLiNS”, or International Lipid-Based Nutrient Supplements Project. The project focuses on formulating and evaluating cost-effective, lipid-based supplements — much like peanut butter — that have shown promise for improving nutrition for children and women in impoverished nations. Recent results indicate that fortified, lipid- or fat-based nutritional supplements provided during pregnancy to women in Bangladesh reduced stunting, abnormally low weight and small head size in babies born to these women.
