Over the past decade, a growing body of literature has emerged suggesting that nutrients play an important role in regulating gene expression, particularly as it relates to the development of disease. Ahmad Heydari, Ph.D., professor of nutrition and food science, is at the forefront of this growing field with his investigation of the link between folic acid and gastrointestinal cancer prevention and treatment. “Powerful developments in genetics research have uncovered the potential of nutrients in controlling gene expression and even preventing DNA damage,” Heydari said. “In terms of cancer, a disease caused primarily from DNA damage, the potential for improvements in prevention and treatment is huge.”
