The objectives of the study are 1) to characterize plasma and urinary metabolites that originate from glucobrassicin, 1-methoxyglucobrassicin, 4-methoxyglucobrassicin, and 4-hydroxyglucobrassicin, which are the major indole glucosinolates found in broccoli, and 2) to identify novel plasma and urinary metabolites following broccoli consumption that may have roles in reducing the risk of cancer.
Consumption of Brassica vegetables is inversely associated with incidence of several cancers, including cancer of the lung, stomach, liver, colon, rectum, breast, endometrium, and ovaries. Brassicas are a good source of many nutrients, but the unique characteristic of Brassicas is their rich content of glucosinolates. Breakdown products of indole glucosinolates in Brassica vegetables show promise for reducing the risk of cancer, but have received comparatively less research attention than those of aliphatic glucosinolates. The aim of this study is to investigate plasma and urinary metabolites of indole glucosinolates from broccoli and to identify novel metabolites that may have roles in reducing cancer risk.

Hospital or other institutional ethics committees established to consider the ethical dimensions of patient care. Distinguish from ETHICS COMMITTEES, RESEARCH, which are established to monitor the welfare of patients or healthy volunteers participating in research studies.
Human experimentation that is not intended to benefit the subjects on whom it is performed. Phase I drug studies (CLINICAL TRIALS, PHASE I AS TOPIC) and research involving healthy volunteers are examples of nontherapeutic human experimentation.
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
