The relationship between DNA and genetic and serious diseases



The idea that a significant part of diseases is determined by our DNA is quite common. However, Canadian scientists conducted a study and stated about the opposite results.

According to a study by scientists from the University of Alberta, most diseases are little dependent on DNA. Where the lifestyle has a greater impact.

The essence of the study

A meta-analysis of data over the past two decades, which examined the relationship between genetic mutations and serious diseases, suggests that there is an “unstable causal relationship” between genetics and most diseases.

The data obtained indicate that DNA is not your destiny, it cannot significantly determine the risks of diseases, says study author David Wishart.


What diseases are genetically determined

According to scientists, many types of cancer, diabetes, Alzheimer's disease and other serious diseases are determined by genetics at best by 5-10% .

The exceptions were attributed to Crohn's disease, celiac disease, and macular degeneration. These diseases are determined by genetics on average 40-50% .

Relative to other diseases, metabolism, lifestyle, nutrition, environmental factors, the influence of chemicals, bacteria and viruses are much more affected.
