Extension/Research Interests :

My research interests are varied: both human and wildlife nutrition. Presently, my nutrition interests are primarily focused on humans and driven by a quote by McCance and Widdowson (1940). “A knowledge of the chemical composition of foods is the first essential in dietary treatment of disease or in any quantitative study of human nutrition.” =Integrity of food composition data as it relates to today’s foods and evaluation of food intake data =Misuse of nutrient composition information, especially on the internet =Bioavailability of nutrients – specifically using a Caco-2 cell culture system to compare the amount of iron being absorbed from different foods =Functionality of nutrients and sub-clinical manifestations of nutrient deficiencies – specifically iron =Evaluation of standard medical practice blood tests to evaluate iron deficiencies =The relationship of nutrient deficiencies to the increasing incidence of autism
