Transcript and Presenter's Notes

Title: Nutrigenomics


1
Nutrigenomics
2
Nutrigenomics
  • Science exploring connections between nutrition
    and gene function
  • Dietary strategies to prevent and treat chronic
    disease

3
Fundamental Principles
  • Dietary components bioactive molecules that
    control gene function
  • Individual genetic makeup and nutrient
    requirements
  • Nutrition and lifestyle manipulated according to
    genes
  • Diet responsive genes and chronic disease
  • Individualized dietary intervention

4
Initiators
  • Human genome project
  • Nutrients are potent dietary signals influencing
    the metabolic programming of cells
  • Hereditary factors can predispose complex chronic
    disease

5
Case in Point
  • -- Interaction of genetic profile with
    environmental exposure
  • Rising unhealthy weights in past decades linked
    to obesity, atherosclerosis and T2D
  • Incidence of chronic disease suggests exposure to
    bad foods cause disease
  • YET not all develop atherosclerosis or T2D so
    must be genetic involvement
  • Thrifty gene

6
The Future
  • Very new science
  • Many complex mechanisms to understand, system
    biology techniques
  • Functional foods
  • Challenges in designing individual diets,
    creating products, and education public
