Today, we know that gene expression is not only mediated by DNA coding, which represents only 2% of genomic expression. It is heavily influenced by informational signals received from the environment by non-coding DNA, which represents the remaining 98%, called “junk DNA”.
Harmful signals emanating from the environment cause disharmony, so that the human body responds, changing the phenotype without changing the genotype. This change is reflected in our physiology. These signals include information about the air we breathe, the food we eat, the impact of the electromagnetic environment and even more than 50,000 daily thoughts.
In summary, the Epigenetics studies how our lifestyle influences our genes causing a certain people, from a certain part of the globe, to have social, cultural habits, food and a specific natural propensity for a certain type of disease, through their own lifestyle.
