We're all being told that our genes are responsible for our health, and they produce a blueprint that determines everything for life. But new research has found they are not set in stone - and that our genes can be altered by our environment, and almost instantly.
A new report from the University of California, Berkeley shows that epigenetics, where temporary changes in gene function happen because of the environment, may play a bigger part in disease than even the genetic blueprint.
We already know that what a woman eats while pregnant affects the baby's health, and these small interferences with our genetic make-up happen all the time, and from many sources, say scientists.
