Nutritional Sciences and Toxicology

University of California, Berkeley


The research and curriculum of the Department of Nutritional Sciences and Toxicology address the experimental biology of nutrients, phytochemicals, and diet-borne toxicants; using the techniques of modern biology and chemical analyses to understand the relationships among diet, the metabolic genome, and optimal health/chronic disease. Our goals are to determine the molecular mechanisms of diet's effects on health and the contribution of individual genotype to dietary responses and disease risk. This approach of metabolic biology will provide detailed insight into the impact of diet on human health and chronic disease risk. We seek to translate lab and model systems data to human physiology and to provide outreach through cooperative extension.
