In his prolific postings on Epigenetics, Erling has offered many important quotes from the writings of Epigenetic expert, Bruce Lipton, PhD (The Biology of Belief). It might be that most of our readers havent bothered to get into this relatively new science since very often people mention their familial history as part of their afib dilemma.
For those afibbers who may not be familiar with the term, Epigenetics, or the thinking that says, our genes are not our destiny
the following comments from a teleconference on the topic of Epigenetics: The Study of Changes in Gene Function that Occur Without a Change in the DNA Sequence, discusses the influence of thought, nutrition, stress and environment on your genetic code and how not to be defined by your DNA., may be useful.
While there may be may links to and genes identified with atrial fibrillation, it is not a given that the lineage has to continue. We do have the power to change the gene expression (Epigenetics) and while this is not new, it is definitely important to gain a working knowledge of what this means
not only for afib, but diabetes, hypertension, cancer and more.
Quotes & Excerpts
Epigenetics is a way we can reprogram our genes much like a computer which can be reprogrammed without changing any of the hardware. You can upgrade your computer but you dont have to swap out the hard drive.
We now know the epigenome is changeable. Epigenetics is any change in gene expression that has been caused by a means other than the underlying DNA. The DNA stays the same (the genome) but the Epigenome is what we can effect or change with nutrients, food, our environment, chemicals, medications, and so on.
There is some confusion about the phenotype expression connection. Phenotype typically refers to color of hair, eyes which are more set in stone; but then epigenitcally, consider a set of set of identical twins and ask how can one twin get heart disease and the other get cancer when they have identical genes-- so their phenotypic expression
(the heart disease or cancer) was mediated by their epigenetics or their epigenome.
People still seem to have the idea that their genes are their fate
ie, if every male in their lineage has had a heart attack in their forties or they all died of cancer (or have atrial fibrillation my comment), many have the fatalistic opinion that those are the genes or the cards I was dealt. Using the card analogy, we can be dealt a strong hand or a weak hand and we still have to play the cards and we can still win with a weak hand and we can lose from the strong hand. It seems that much of the general public does not understand how lifestyle choices, dietary choices and stress levels all play a role.
So how can our understanding of Epigenetics actually impact our life and our and outcomes?
DNA is still the big player in town but we now know it is not the only mechanism of inheritance. We can actually change what happens to our children and grandchildren. The more scientists look at how the genes work, the more they realize there is a lot more going on that what was previously thought, so the epigenetic changes are actually contributing to some of these disease processes. Example: diabetes and lifestyle-induced diseases that we are seeing escalate in our practices that are burdening the healthcare system. A lot of these are physiologic mechanisms that are occurring via epigenetic mechanisms in genes in our cells down-regulating certain proteins that lead to downstream consequences.
Whats interesting and what Epigenetics means is that people can actually begin to feel empowered again. Through choices that people make, diet, nutrition, lifestyle, environmental awareness, looking for environmental toxicities all with an attempt to promote health, but on a much deeper level
really looking to protect our genome.
So this throws out the window the excuse that my parents were diabetic, or my parents were fat. So guess what? That not need be your fate. Certainly if you do the same things your parents did to express their phenotypic genome, you can expect the same. But if you understand you can change it through the diet, lifestyle, stress reduction methods, you arent caught up in this mind-set that my genes are my destiny. And you can actually play a role in the outcome so it is a very powerful concept in that respect. These are modifiable factors everyone can change every day in their life by making the appropriate choices.

Bottom line:
Its time to catch up with the science about how you are in control and your genes do not have to be your destiny.
