title: Ethical, legal and social issues in nutrigenomics: the challenges of regulating service delivery and building health professional capacity.
abstract: Nutrigenomics, the conjunction of molecular nutrition with human genomics, is among the first publicly available applications of the human genome project. Nutrigenomics raises ethical, legal and social issues particularly with respect to how the public may access nutrigenetic tests and associated nutritional and lifestyle advice. Current regulatory controversy focuses on potential harms associated with direct-to-consumer (DTC) marketing of nutrigenetic tests and especially the need to protect consumers from unreliable tests, false claims and unproven dietary supplements. Nutrigenomics does, however, offer the potential of important health benefits for some individuals. The regulation of nutrigenomic services is slowly evolving, but there is little indication of increased professional capacity to support service delivery. Primary care physicians have minimal training in nutrition and genetics, and medical geneticists are in high demand and short supply. Dietetic practitioners are experts in nutrition science and interest in nutrigenomics is growing among members of this professional group. However, as with physicians, dietetics practitioners would require considerable training to bring nutrigenomics into their practice capacity. A downside of regulatory restrictions on direct consumer access to nutrigenomics companies is that responsible businesses may be hindered in meeting emergent public demand while health care professional groups have not yet developed capacity to provide nutrigenomics services.
