People typically think of food as calories, energy and sustenance. However, the latest evidence suggests that food also “talks” to our genome, which is the genetic blueprint that directs the way the body functions down to the cellular level.
This communication between food and genes may affect your health, physiology and longevity. The idea that food delivers important messages to an animal’s genome is the focus of a field known as nutrigenomics. This is a discipline still in its infancy, and many questions remain cloaked in mystery. Yet already, we researchers have learned a great deal about how food components affect the genome.
I am a molecular biologist who researches the interactions among food, genes and brains in the effort to better understand how food messages affect our biology. The efforts of scientists to decipher this transmission of information could one day result in healthier and happier lives for all of us. But until then, nutrigenomics has unmasked at least one important fact: Our relationship with food is far more intimate than we ever imagined.
