TOXIC Overload!
Take This Short Quiz To Determine Your Body Toxicity Risk

Based on research at Tulane University School of Medicine, scientists have proven that exposure to stress, violence, or other traumatic events in the family during childhood can leave a lasting impact on stretches of DNA – so-called telomeres. NCBI is evidence that stress and a stressful home environment can permanently affect chromosomes. Telomeres are sequences of DNA that are found at the end of chromosomes and act as protective caps, protecting the chromosomes from merging or degradation, which can lead to the extinction of the cells. They are a type of mobile timer that limits the cell’s replication to the point where they can no longer multiply. Shorter telomeres are associated with different diseases:

To find the relationship between exposure to disturbed and violent events in his youth on the one hand and telomere length, on the other hand, scientists have made several studies.

Exposure to Stress and Your DNA

According to the family environment and exposure to traumatic events in New Orléans, the team interviewed the parents of 80 children aged 5 to 15 years. When analyzing samples of DNA taken from these children, the team found a connection between exposure to domestic violence or family disruption and the length of telomeres. The children exposed to negative events in the family have much shorter telomeres compared with children who lived in calmer and more stable families. The researchers found differences between girls and boys also. They found that these traumatic events affect more of the length of telomeres in girls. For the boys under 10 years of age, they found that the good education of their mother has a protective effect. The stressful family situation affects children’s DNA cells. The greater exposure of these children to stress, the lower the length of their telomeres was. It includes other factors such as the age of the child, parents, education, and social status. This is the second study that proves there is a connection between a stressful home environment and the length of telomeres in children. The first study shows that children, who lived and grew up in poor and unstable homes, also had shorter telomeres than children raised in situated families. These studies highlight that omitting intervention in the domestic environment is inevitable to reduce the permanent biological impact of a poor childhood.

Poor Nutrition and Your DNA

Scientists Dean Ornish, MD, and Elizabeth Blackburn, Ph.D. made NCBI of how diet and lifestyle affect the length of telomeres. In September 2013, they conducted a study on men with early-stage prostate cancer. They subjected them to a low-fat, vegetable diet, meditation, exercise, and time spent with family and friends. After 5 years, the length of telomeres in subjects increased by 10%, while in the other, out of this survey – fell by 3%. Plant foods, rich in phytochemicals and antioxidants are great for telomeres affected by oxidative stress. Other independent studies produced the following facts associated with longer telomeres:

Folic acid and other nutrients important for methylation;Vitamin C, Vitamin E, selenium, and other antioxidants;Omega-3 fatty acids;Higher levels of vitamin D – because of its inflammatory effect;Physical activity in leisure time;Stress Management and Meditation.

The findings of Dean Ornish and Elizabeth Blackburn have shown that a combination of healthy food, avoiding stress, exercise, and time spent with loved ones is a healthy lifestyle.
