Aging is a natural part of life and it can’t be stopped. Or at least, that’s what we used to think. Researchers at Intervene Immune, Stanford, the University of British Columbia, and UCLA believe that our epigenetic clock can be changed, suggesting that there may still be ways for humans to live longer. In the following article, we will discuss the findings associated with epigenetics and aging.
The epigenetic clock is a measurement of biological age that can be used to estimate the chronological age of humans or other organisms by testing several patterns of DNA methylation. Although the age estimated by the epigenetic clock frequently correlates with chronological age, it is not fully understood if DNA methylation profiles in the epigenetic clock are directly associated with aging.
For many years, researchers have observed age-related changes in gene expression and DNA methylation. However, the idea of using an “epigenetic clock” to be able to estimate chronological age by testing several patterns of DNA methylation was first proposed by Steve Horvath where it gained popularity after his 2013 research study was published in the journal Genome Biology.
Epigenetic clocks are used in forensic studies to determine the age of an unknown person through blood or other biological samples at the scene of a crime and in diagnostic screens to determine increased risks for diseases associated with aging, including a variety of cancers. Epigenetic clocks can also highlight whether several behaviors or treatments can affect epigenetic age.
The main reason that epigenetic clocks and DNA methylation are used to estimate the chronological age of humans or other organisms is that they correlate very well with the chronological age in the subjects tested. The first research study on the epigenetic clock that Steve Horvath published in 2013 included 353 individual CpG sites identified from previous research studies.
Of these sites, 193 become more methylated with age and 160 become less methylated, which leads to the DNA methylation age estimate that is used to determine the epigenetic clock. Throughout all outcome measures, including all ages of subjects, Horvath observed a 0.96 correlation between the epigenetic age he calculated and the true chronological age, with an error rate of 3.6 years.
Current epigenetic clocks are also being evaluated to help further improve age prediction as well as the diagnostic and/or prognostic abilities of these tests. Further evaluations using NGS approaches ultimately have the potential to improve epigenetic clocks, making them more comprehensive by extending the evaluation of DNA methylation sites to all CpG sites in the genome.
Research studies have demonstrated that cancer can change the epigenetic clock. These observations suggest that the epigenetic clock can change under certain conditions. Therefore, it is possible that the epigenetic clock can be manipulated through changes in behavior or treatment strategies to slow it down or potentially reverse it, allowing humans to live longer and healthier lives.

By changing our epigenetic clocks, healthcare professionals may also be able to regulate age-related health issues, such as inflammation and joint pain. These could potentially be helpful for chiropractic care, an alternative treatment option that uses spinal adjustments to carefully restore the alignment of the spine. – Dr. Alex Jimenez D.C., C.C.S.T.

Yes, eating just one boiled 80g (2¾oz) carrot gives you enough beta carotene for your body to produce 1,480 micrograms (mcg) of vitamin A (necessary for skin cell renewal). That’s more than the recommended daily intake of vitamin A in the United States, which is about 900mcg. It’s best to eat carrots cooked, as this softens the cell walls allowing more beta carotene to be absorbed. Adding healthier foods into your diet is a great way to improve your overall health.
