I have recently come across the science of epigenetics because of the new diet I am using to fight inflammation. Epigenetics is the science pertaining to gene expression. In “The China Study” (written by T. Colin Campbell, PhD and his son Thomas M. Campbell II, MD) Dr. Campbell wrote:
"Genes function only be being activated, or “expressed,” and nutrition plays a critical role in determining which genes, good and bad, are expressed. We can safely say that the origin of every single disease is genetic. Our genes are the code for everything in our bodies, good and bad. Without genes, there would be no cancer. Without genes, there would be no obesity, diabetes, or heart disease. And without genes, there would be no life.
This might explain why we are spending hundreds of millions of dollars trying to figure out which gene causes which disease and how we can silence the dangerous genes. This also explains why some perfectly healthy young women had had their breasts removed simply because they were found to carry genes that are linked to breast cancer. This further explains why the bulk of resources in science and health in the past decade has shifted to genetic research."
Dr. Campbell goes on to explain that some genes remain dormant while others express themselves. “What causes some genes to remain dormant, and others to express themselves?”. Of course Dr. Campbell’s focus in his book is all about nutrition, but as Dr. Campbell and other geneticists point out, our environment causes genes to be turned “off” or “on”.
Recently I picked up a new “National Geographic” magazine and the whole magazine is called “Your Genes - A User’s Guide - 100 Things You Never Knew”. Most of the magazine talks about gene manipulation and way over on p. 102 it lists the 97th thing we didn’t know called: “epigenetics”. It’s as though they don’t want to put much if any emphasis on epigenetics and they treat it as part of science that they have to include. On the last couple of pages National Geographic writers ask: “Are We Playing God? Should We?”
Some would say that in a sense, epigenetics could be a very vague way to manipulate genes, but I think it is good stewardship and could be the right way to “manipulate” or turn our genes “on” or “off”. On the other end of the spectrum, if scientists manipulate genes within the embryo then that becomes something totally different.
I found a really good YouTube video that explains epigenetics, and it’s called Epigenetics and the Bible here: https://www.youtube.com/watch?v=dygiebQ-cuo&t=2602s
