Jere D. Haas is the Nancy Schlegel Meinig Professor of Maternal and Child Nutrition in the Division of Nutritional Sciences, College of Human Ecology, at Cornell University, in Ithaca, New York. He is also International Professor of Nutrition in Cornell's College of Agriculture and Life Science and Director of the campus-wide Human Biology Program. He received his Ph.D. in Biological Anthropology from the Pennsylvania State University and has been on the Cornell University faculty for 37 years. He is currently conducting research on the functional consequences of iron deficiency on physical and cognitive performance. The emphasis is on the effects of moderate iron deficiency on various aspects of physical performance and behavior in children and young women and how measures of performance relate to everyday productivity and social and economic well being. He also conducts research on food based interventions to reduce micronutrient malnutrition. Professor Haas conducts research on these and related topics in maternal and child nutrition in the United States, Mexico, the Philippines, Rwanda and India. Professor Haas served as vice-president and president of the American Association of Physical Anthropologists and serves on the Expert Advisory Panel for Nutrition of the World Health Organization and the Technical Advisory Group on Food and Nutrition of the Pan American Health Organization. He served as Director of the Division of Nutritional Science at Cornell from 1998 to 2003.

Current Research Activities:
My research deals with nutrition problems of women and young children, with a primary emphasis on iron deficiency and protein and energy undernutrition in developing countries. For 37 years my research has focused on understanding the functional consequences of malnutrition on physical performance, physical activity and behavior. Current studies are designed to identify useful functional indicators that can be used to evaluate nutrition interventions that are designed to improve iron status in women and children.
We are currently examining two novel approaches to improving dietary iron intakes by enhancing the nutrient quality of staple food crops such as rice, pearl millet and beans and through the fortification of table salt. These staple foods and table salt are consumed by a large number of the most nutritionally vulnerable population groups in Asia, Africa and Latin America. In collaboration with colleagues from the International Rice Research Institute (IRRI), the University of the Philippines at Los Banos and the Pennsylvania State University we have shown an improvement in body iron status in women who consumed an experimental variety of rice bred for high iron content. The research was conducted in a population of iron deficient women whose rice consumption and dietary intakes were closely monitored. The women were fed either the genetically enhanced rice or a control variety for 9 months, after which, they were tested for improvements in iron status and behavioral and cognitive performance. This research was the first to show that “biofortification" strategies can improve the micronutrient status of human subjects at risk of deficiencies in developing countries.
We recently completed the data collection phase a second "feeding trial" of another biofortified staple, black beans, in school children in southern Mexico. Early results from this study indicates that primary school children who consume the biofortified beans for 100 days show improved tissue level iron status (transferring receptor values decline) compared to controls. This effect is most apparent in children who were the most iron deficient at baseline and those who consumed the most beans throughout the study. This study also tested for changes in physical activity in these children. The research is being conducted in collaboration with scientist at the Mexican National Institute of Public Health (INSP), HarvestPlus Project of the International Food Policy Research Institute (IFPRI) and the Center for Tropical Agriculture (CIAT) in Cali, Colombia.
Another feeding trial with biofortified beans, supported by HarvestPlus, is being planned for 2013 in Rwanda through collaboration with scientists at the National University of Rwanda, the University of Oklahoma and the Pennsylvania State University. This study will test for the effect of improved iron nutrition on cognitive function, energetic work efficiency and physical activity in university women. We recently currently data collection for a study of the impact on iron status of consuming iron biofortified pearl millet in western India in collaboration with colleagues at the SNDT Women’s University in Mumbai. In this study we are also assess the effects of the intervention on functional outcomes using similar measures to those proposed in the Rwanda study.
We have also recently completed a study that tested the effectiveness of consuming table salt (DFS) that is double fortified with iodine and encapsulated iron in India through a program administered by the Micronutrient Initiative of Canada. Preliminary results from this year long intervention trial has shown significant improvements in all measures of iron status in women who consumed DFS compared to controls. This project will also test whether consumption of double fortified salt improves worker productivity, physical activity and cognitive function in women who pick tea on Indian tea estates in north Bengal.
