Berg (born February 18, 1932) is an American international development authority, most notable for his advocacy and large-scale implementation of strategies to address malnutrition, especially among children and pregnant women.
Berg's professional focus on nutrition spans more than half a century and has earned him wide recognition for stimulating a new policy approach to international nutrition assistance.
His work has helped to transform the way development agencies and national governments think about the problem of malnutrition as a fundamental component of economic growth.
His innovative planning and multisectoral operational work, particularly during his long tenure as the senior nutrition officer at the World Bank (1972–95), have modeled a number of practices that other donor institutions and countries now often incorporate into their own projects.
Furthermore, Berg's efforts to transform development assistance for nutrition have prompted a number of academic training programs for nutritionists to expand their curriculum to include coursework in nutrition policy, planning, and implementation, creating a new career path for graduates.
In a 1997 survey of the international nutrition community, Berg was the one most often cited as a role model for young persons entering the field.
In 2008, the United Nations Standing Committee on Nutrition honored Berg as one of the first recipients of the United Nations Achievement Award for Lifelong Service to Nutrition, citing him at the presentation as "a global giant in nutrition history.
