Cancer, cardiovascular disease, diabetes (type-II),
and obesity are major health concerns in the U.S. and in other developed and developing regions around the world. These chronic diseases are in many
circumstances considered to be preventable via various facets of
lifestyle. Prominent among these
lifestyle factors is the type and amounts of the foods eaten, particularly
those foods of plant origin. While there
has been some success in efforts to breed plants for improved health-related
attributes, these examples are remarkably limited in number and scope. Given the profound physical, psychosocial and
economic consequences of chronic diseases and the potential of food crops to
meaningfully reduce chronic disease risk, we decided to challenge scientists in
a broad array of disciplines to join forces in an effort to harness existing
and emerging capabilities in agriculture and the biomedical sciences to reduce
chronic disease prevalence. We have
coined the term “biomedical agriculture” to describe this transdisciplinary
research effort. This presentation will highlight
promising examples of the discovery process being used to develop more
healthful food crops, as well as underscore challenges being encountered in
pursuing this strategy. Topics to be
covered include: the role of health profiling of a crop in designing a program
of research, exploitation of the
biodiversity of crop varieties for identifying extremes in health
characteristics, selection of model systems for evaluating health traits, and
the use of “omics technologies” and traditional
approaches to facilitate rapid characterization of traits of interest. The ultimate goal of this effort is to define a discovery process that identifies traits that can be used by
plant breeders to improve a crop's human health attributes. It is critical that this be done in a manner
that will be accepted within the agricultural community so that crops of
interest become widely available to consumers. As the field of
biomedical agriculture evolves, consumer are likely to be informed about
currently unappreciated health benefits of existing food selections and to be
offered new selections with improved disease prevention characteristics. It is anticipated that future dietary
recommendations will be targeted not only for specific food crops, but also for
varieties within a crop.
