Negative Thoughts Harm Your Health By Damaging DNA

Lose your temper on the road? Frustrated with colleagues at work? You may be cutting your life short, warns molecular biologist Elizabeth Blackburn–who won the Nobel Prize in Medicine in 2009–and health psychologist Elissa Epel, who studies stress and aging.

The authors claim in their new book, The Telomere Effect, that negative thoughts harm your health at the DNA level. Research has shown that a person’s “social relationships, environments and lifestyles” affect their genes. “Even though you are born with a particular set of genes, the way you live can influence how they express themselves.”

Blackburn and Epel say components of DNA called telomeres determine how fast your cells age. Short telomeres are one of the major reasons human cells grow old, but lab tests have shown that they can also grow longer. In other words, aging “could possibly be accelerated or slowed -and, in some aspects, even reversed.”

Research Proves That DNA Is Reprogrammed by Words and Frequencies

The aging and lifespan of normal, healthy cells are linked to the so-called telomerase shortening mechanism, which limits cells to a fixed number of divisions. During cell replication, the telomeres function by ensuring the cell’s chromosomes do not fuse with each other or rearrange, which can lead to cancer. Blackburn likened telomeres to the ends of shoelaces, without which the lace would unravel.

In one study, telomere length, an emerging biomarker for cellular and general bodily aging, was assessed in association with the tendency to be present in the moment versus the tendency to mind wander, in research on 239 healthy, midlife women ranging in age from 50 to 65 years.

“People who score high on measures of cynical hostility tend to get more cardiovascular disease, metabolic disease and often die at younger ages. They also have shorter telomeres.”

Pessimism shortens telomeres too.”When pessimists develop an aging-related illness, like cancer or heart disease, the illness tends to progress faster… They tend to die earlier,” warn the authors.

Ruminating over a bad situation is also destructive. “Rumination never leads to a solution, only to more ruminating… When you ruminate, stress sticks around in the body long after the reason for the stress is over.” The resulting depression and anxiety only make your telomeres shorter.

Trying to suppress thoughts and feelings makes matters worse. “The more forcefully you push your thoughts away, the louder they call out for your attention… In a small study, greater avoidance of negative feelings and thoughts was associated with shorter telomeres.”

Even lack of focus is bad for telomeres because “when people are not thinking about what they’re doing, they’re not as happy as when they’re engaged.” To reverse the harm to telomeres, try meditation and long-distance running.

Soft Drink Consumption Will Age You As Fast As Smoking – 10 Reasons To Avoid Them

The message to stop smoking issued by public health officials has been nothing less than paramount, repetitive and consistent in the last several decades. What about soft drinks? Daily consumption of just a half-liter of soda is linked with 4.6 years of additional biological aging, effects comparable to that of smoking, finds a new study.

The study found that drinking soft drinks is associated with cell aging, suggesting sugar-sweetened soda consumption might promote disease independently from its role in obesity. (more…)

3 Secret Weapons Against Stress, Inflammation, and Insomnia

Secret Weapon 2

Stress, inflammation, and lack of sleep shorten your telomeres—which can shorten your life.
Three protectors help you overcome the effects.
You probably already know that inflammation, stress, and lack of sleep aren’t good for you. You may not know, however, that these things have a huge impact on your cells.

More specifically, they all affect the length of your telomeres—which can actually affect the length of your life.

What are Telomeres?

2 Billion People Have This Mineral Deficiency Which Reduces The Common Cold

Dietary shortages of crucial minerals like zinc may be keeping almost a third of the world’s people from optimizing their immune system. Research shows that adequate zinc intake reduces the severity and duration of illness caused by the common cold.



Experts say as many as two billion people around the world have diets deficient in zinc – and studies at Oregon State University and elsewhere are raising concerns about the health implications this holds for infectious disease, immune function, DNA damage and cancer. (more…)

Genetically Modified DNA Transfers From Food to Human Blood

The inclusion of genetically modified (GM) plants in the human diet has raised concerns about the transfer of transgenes from GM plants to humans. Contrary to the claims by biotech giants such as Monsanto, a report in PLOS One shows that that meal-derived DNA fragments are large enough to carry complete genes as they enter the human circulatory system. In some of the human samples studied the relative concentration of plant DNA was higher than the human DNA.

 

The potential effects of horizontal gene transfer on human health have always been stated as an important item in the safety assessment of genetically modified organisms. However, the persistence in the human gut of DNA from dietary GM plants has been relatively unknown since their inception. (more…)

Greater Lifetime Pesticide Use Causes Telomere Shortening

Greater Lifetime Pesticide Use Causes Telomere Shortening

Researchers from Northwestern University’s School of Medicine have determined that the use of certain pesticides over a lifetime produces a shortening of chromosome telomeres.

The researchers tested 1,234 men as part of a study of 57,310 licensed pesticide contractors – from the Agricultural Health Study, orchestrated by the National Cancer Institute, the National Institute of Environmental Health Sciences, and the U.S. Environmental Protection Agency. This particular study was conducted in partnership with the Robert H. Lurie Comprehensive Cancer Center. (more…)

Scientists Discover Chinese Herbal Cure Secret

Scientists in the United States on Sunday offered a molecular-level explanation for how a Chinese herbal medicine used for more than 2,000 years tackles fever and eases malaria.

The herb is an extract of the root of a flowering plant called blue evergreen hydrangea, known in Chinese as chang shan and in Latin as Dichroa febrifuga Lour.

Chang shan’s use dates back to the Han dynasty of 206 BC to 220 AD, according to ancient documents recording Chinese oral traditions. (more…)

Breaking Study Is The First To Show Link Between Being Present In The Moment And Ageless DNA

Scientific studies have suggested that a mind that is present and in the moment indicates well-being, whereas shifting our energy to the past or future can lead to unhappiness. Now, a preliminary UCSF study shows a link between mind wandering and aging, by looking at a biological measure of longevity within our DNA.

In the study, telomere length, an emerging biomarker for cellular and general bodily aging, was assessed in association with the tendency to be present in the moment versus the tendency to mind wander, in research on 239 healthy, midlife women ranging in age from 50 to 65 years.

Being present in the moment was defined as an inclination to be focused on current tasks, while mind wandering was defined as the inclination to have thoughts about things other than the present or being elsewhere. (more…)

Should You Worry About Genetically Modified Food?

labworkA new study came out last month out of France. In it, researchers found that rats on diets consisting of 11%, 22%, and 33% Roundup-resistant genetically modified corn developed far more mammary tumors than control rats on non-GMO corn diets. GMO diet rats died earlier and in greater numbers. Why is this study notable amidst all the other studies that seem to show the safety of GMOs? Well, it’s one of the few long term GMO feeding studies, lasting a full two years, which, to a rat, is the equivalent of 60 of our human years. The other safety studies which found no evidence of toxicity in GM foods tend to last just 90 days, or 15 rat years. In other words, the French study studied rats over the course of an entire lifespan, whereas other studies have looked at rats for a relatively brief snippet of their lives. Cancer generally develops over a lifetime, as you probably know, so this would appear to be more relevant to human health than the shorter trials. (more…)
