Stop Blaming Your Genes – You Are In Control

September 3, 2016

Every thought creates a physiological response in the body, or in other words, every thought we think produces a physical reality. Esoteric and spiritual teachers have known for ages that our body is programmable by language, words and thought. This has now been scientifically proven and explained.

Studies at the world-leading Minnesota Center for Twin and Family suggest that many of our traits are more than 50% inherited, including obedience to authority, vulnerability to stress, and risk-seeking. Researchers have even suggested that when it comes to issues such as religion and politics, our choices are much more determined by our genes than we think.

Many find this disturbing. The idea that unconscious biological forces drive our beliefs and actions would seem to pose a real threat to our free will. We like to think that we make choices on the basis of our own conscious deliberations. But isn’t all that thinking things over irrelevant if our final decision was already written in our genetic code? And doesn’t the whole edifice of personal responsibility collapse if we accept that “my genes made me do it”?

Genes are only part of our health story, explains Jeffrey S. Bland, PhD, FACN, FACB, author of the book, Genetic Nutritioneering: How You Can Modify Inherited Traits and Live a Longer, Healthier Life. The propensity for certain health conditions that you inherit from your family is not, by a long shot, the sole determinant of whether or not most folks will get sick. Your lifestyle choices have a significant impact, especially when it comes to chronic illnesses such as heart disease.

Epigenetic Switch

In the fields of infant nutrition, diabetes, obesity, and the metabolic syndrome, the term “metabolic programming” has been coined to give a name to the observation that environmental experiences early in life may be “genomically” remembered and give rise to health outcomes manifesting later in life. Epigenetics emerges as an important mechanism underlying this phenomenon.

Epigenetics is the phenomena whereby genetically identical cells express their genes differently, resulting in different physical traits. Researchers from the Boston University Cancer Center published two articles about this in Anticancer Research and Epigenomics.

Cancer progression is extremely complex, however. It also is well known that new mutations and the activation of more cancer causing genes occur throughout the development and progression of cancer.

“If we believe that everything in nature occurs in an organized fashion, then it is logical to assume that cancer development cannot be as disorganized as it may seem,” said Sibaji Sarkar, PhD, instructor of medicine at BUSM and the articles corresponding author. “There should be a general mechanism that initiates cancer progression from predisposed progenitor cells, which likely involves epigenetic changes.”

Increasingly, biologists are finding that non-genetic variation acquired during the life of an organism can sometimes be passed on to offspring–a phenomenon known as epigenetic inheritance.

The majority of epigenetic changes occur at specific times in an individual’s life, from their time in the womb, to the development as newborns, then in puberty, and again in old age.

Environmental factors that influence epigenetic patterns — e.g., diet, epigenetic disruptors in the environment such as chemicals, etc. – may also have long term, multigenerational effects.

In recent years, faith in the explanatory power of genes has waned. Today, few scientists believe that there is a simple “gene for” anything. Almost all inherited features or traits are the products of complex interactions of numerous genes combined with processes we have no concept of. However, the fact that there is no one genetic trigger has not by itself undermined the claim that many of our deepest character traits, dispositions and even opinions are genetically determined. This worry is only slightly tempered by what we are learning about epigenetics, which shows how many inherited traits only get “switched on” in certain environments.

The common mistake people make is to assume that if, for example, a disease is 90% heritable, then 90% of people with that disease inherited the condition from their parents. But heritability is not about “chance or risk of passing it on”, said Tim Spector, Professor of Genetics and Author. “It simply means how much of the variation within a given population is down to genes. Crucially, this will be different according to the environment of that population.
