A New Science: Nutritional Genomics

Scientists are continually finding evidence of how our bodies are designed and somewhat destined. Each of us possesses our own unique DNA. It’s what makes up our genetic blueprint. The study of human genetics continues to reveal just how unique each individual is and their genetic make-up. Another exciting outcome of nutrition research and science is the study of Nutritional Genomics, which includes nutrigenomics, and nutrigenetics. According to Ruth DeBusk, Ph.D., R.D., co-author of It’s Not Just Your Genes, “Nutrigenomics is about the individual’s environment acting on the genes and nutrigenetics is about genes acting on the individual’s environment, which include nutrition and lifestyle.” The research on this subject is looking at methods to “…define the best match between our food choices and our genetic makeup, providing a solid foundation upon which to base diet related disease interventions and health promotion approaches…dietary components, as functional foods or dietary supplements, will be used to increase or decrease the expression of particular genes to improve health.” Our genes interact and react to what we put into our bodies. Food is one of a number of environmental factors that plays a part in this process. This new science is expected to ultimately allow us to match our genetic makeup and the types of food and lifestyle choices that will keep us healthiest. It is similar to some tests that have been around for different types of hyperlipidemia (elevated blood fat levels), and cancer(s). Nutritional genomics is a relatively new science, so stay tuned for more information.

In 2008, the Genetic Information Nondiscrimination Act (GINA) was signed into law. This Act “…will protect Americans against discrimination based on their genetic information when it comes to health insurance and employment…and will pave the way for people to take full advantage of the promise of personalized medicine without fear of discrimination.” For more information, go to http://www.genome.gov/27026050
