An innovative clinical trial shows that we can reduce biological age (measured by the Horvath 2013 DNAmAge watch) for more than three years in just eight weeks with diet and lifestyle by balancing DNA methylation.

A first study of this type, reviewed by experts, provides scientific evidence that changes in lifestyle and diet can produce an immediate and rapid reduction in our biological age. Since aging is the main driver of chronic diseases, this reduction can help us live better and longer.

The study, published April 12, used a randomized controlled clinical trial conducted in 43 healthy adult men between the ages of 50 and 72 years. The 8-week treatment program included guidance on diet, sleep, exercise and relaxation, and supplemental probiotics and phytonutrients, resulting in a statistically significant reduction in biological age — more than three years less, compared to controls.

The study was conducted independently by the Helfgott Research Institute, with laboratory assistance from the Yale University Genome Analysis Center, and the results were independently analyzed at McGill University and National University of Yale. Natural Medicine.

The lead author of the study, Kara Fitzgerald ND IFMCP, stated that “the combined intervention program was designed to address a specific biological mechanism called DNA methylation, and in particular methylation patterns. of DNA that have been identified as highly predictive of biological age.We suspect that this approach was the reason for its remarkable impact.These early results seem consistent with the few existing studies that have so far examined the potential of reversal. And it is unique for the use of a safe, non-pharmaceutical diet and lifestyle program, control group and the scope of age reduction. We are currently enrolling participants for a larger study that we hope will corroborate these findings. “

Of the 18 participants included in the final analysis, 8 obtained an age reduction, 9 did not change and 1 increased in the age of methylation. Credit: Kara N. Fitzgerald

Ph.D., chief epigeneticist Moshe Szyf of McGill University and co-author of the study adds: “The uniqueness of Dr. Fitzgerald’s approach is that her essay devised a natural but mechanical strategy aimed at the methylation system of the This study provides the first insight into the possibility of using natural alterations to address epigenetic processes and improve our well-being and perhaps even longevity and shelf life. “

DNA methylation patterns have become one of the main means by which scientists evaluate and monitor biological aging, a term used to describe the accumulation of damage and loss of function. of our cells, tissues and organs. This damage is what leads to the diseases of aging. “Which is extremely exciting,” commented Dr. Fitzgerald, “is that dietary and lifestyle practices, including specific nutrients and food compounds that are known to selectively alter DNA methylation, can have such a large impact on DNA methylation patterns that we know how to predict aging and age-related illness.I think this, along with new possibilities for everyone to measure and track it. DNA methylation years, it will provide significant new opportunities for both scientists and consumers. ”
