ST. LOUIS, Sept. 14, 2012 /PRNewswire/ -- The sequencing of the human genome was once hailed by scientists to be the harbinger of medical miracles. Yet, deciphering our DNA brought us no closer to understanding — much less finding effective preventive approaches for — major chronic diseases.
But new groundbreaking research is uncovering a higher level of complexity beyond genetic variation. Even better news: proper nutrition can produce positive changes at this higher level.
A recent article by the Associated Press highlighted new data the Encyclopedia of DNA Elements (ENCODE) project recently published in Nature – the international weekly journal of science.
"The scientific establishment has finally acknowledged that there is more than just DNA or the genome to explain how chronic diseases develop and how the environment, like nutrition and lifestyle, can have profound effects in altering our health," said Dr. Alfredo Galvez, renowned research scientist at the Center of Excellence in Nutritional Genomics at UC Davis and lead scientific advisor at the Missouri Plant Science Center.
What is the epigenome?
The genome is your body's complete set of DNA and genes. We have more than 300 cell types — skin cells, liver cells, brain cells, etc. — that look and function differently even though they have the same DNA.
The epigenome is made up of the DNA packaging material called histones and chemicals that tell the genome what to do. These chemicals can turn different genes on or off to create different types of cells. For example, the epigenome tells your skin cells to behave like skin cells, liver cells like liver cells, and so on.
