Long-term goal is to elucidate the components of plant foods responsible for their health benefits and adverse effects, as well as the molecular, cellular, and physiological mechanisms of their action. Research is focused on the role of phytochemicals (i.e., phytoestrogens: lignans and isoflavones), alpha linolenic acid, and their interactions with drugs on the development of breast cancer and osteoporosis, as well as their metabolism and biovailability. Studies include biochemical, in vitro (cell culture), animal, and clinical (healthy human subjects and patients) experiments. Food models such as flaxseed, soy, and sesame seed are used. Results should provide guidance in the design of functional foods and nutraceuticals and in the manipulation of diet for risk reduction and treatment of chronic diseases.
