Environment more powerful than your genetics in shaping your immune system

I give a seminar titled “You are Not your Genetics” and it often has people left speechless.

“I’m a strong believer in the power of dirt. This just says the environment plays a huge role in shaping what your immune system looks like. Experience counts more and more as you get older”
Stanford University immunologist Mark Davis, director of Stanford’s Institute for Immunity, Transplantation and Infection, January 2015.

Most people think their disease risk is hereditary when in fact around 97% of modern disease is from poor diet, lifestyle and environmental choices.

“Younger twins were more similar than were older twins, evidence that as the twins aged and were exposed to different environments, their immune systems diverged over time”
Emily Conover, Science Magazine, January 2015. 

Stanford University immunologist Mark Davis, director of Stanford’s Institute for Immunity, Transplantation and Infection, has released details of his research into identical twins, genetics and the immune system. Davis compared 78 pairs of various aged identical twins, with 27 pairs of fraternal (non-identical) twins, using blood samples, proteins and immune cells to track the immune system’s responses.

What did this latest research confirm?

  1. Over 75% of immune system responses were due to non-genetic influencers such as diet, lifestyle and environment
  2. Your immune system is dependent and co-existent with the bacteria you are exposed to in your environment
  3. The identical twins immune systems grew more and more different as they aged and had different experiences
  4. Immunizations were more powerful than genetics in regards to health
