Soon, genetic make-up to decide your diet

Kansas State University researchers say diets could soon be tailored for people according to their genetic makeup.

According to the scientists, nutrigenomics - the study of the effect of food on gene expression - could completely change the future of public health.

Koushik Adhikari, K-State assistant professor of sensory analysis said: "Nutrigenomics involves tailoring diets to someone's genetic makeup.

"I speculate that in five to 10 years, you would go to a genetic counselor or a physician who could help you understand your genetic makeup, and then a nutritional professional could customize your diet accordingly."

Adhikari teamed up with Denis Medeiros, professor and department head of human nutrition, and Jean Getz, former K-State graduate student in human nutrition, for an article on nutrigenomics that appeared in the January issue of Food Technology. Getz, now a student at the School of Osteopathic Medicine at Michigan State University, wrote the article while at K-State.

Nutrigenomics is a growing field of research that combines molecular biology, genetics and nutrition to regulate gene expression through specific nutrients. Nutrients have been shown to affect gene expression through transcription factors, which are biochemical entities that bind to DNA and either promote or inhibit transcription of genes.

By understanding the roles of specific nutrients and how they might cause diseases, scientists could recommend specific foods for an individual based on his or her genetics.

Adhikari said: "Scientists are looking at the molecular mechanisms in the body.
