In this clip, Dr. Steve Horvath describes research suggesting that caloric restriction, especially when it is reversing obesity or metabolic syndrome, may slow epigenetic aging.

In this clip, Dr. Steve Horvath discusses whether epigenetic clocks play causal roles in aging.

Methylation and demethylation are critical processes in development and interfering with the enzymes that carry out these two opposing processes can play critical roles in epigenetic age.

Some epigenetic clock evidence reinforces the idea that accelerated aging may be a consequence of chronic inflammation.

As techniques are developed to differentiate and transdifferentiate cells from one cell type, such as a fibroblast, into another, such as a neuron, interesting patterns of effects on epigenetic age are revealed.

A study using a mouse model of premature aging showed that short-term expression of four special factors which reverse epigenetic age ameliorated cellular and physiological hallmarks of aging and prolonged lifespan.

Scientists have observed that the epigenetic clock of transplanted cells and their descendant lineages synchronize with the donor rather than the recipient, a fascinating phenomenon that offers promise for the idea of rejuvenation in humans.

Conventional health advice, such as healthy eating, physical activity, and education level are linked with slowed epigenetic aging, albeit weakly, and obesity, sleep deprivation, and smoking are linked with accelerated epigenetic aging.

In this clip, Dr. Steve Horvath discusses how epigenetic aging differs from senescence-mediated aging.

The DNAm GrimAge epigenetic clock may be a more reliable predictor of healthspan and lifespan than traditional hallmarks of aging like telomeres.

A person's epigenetic age correlates with their risk for developing major diseases of aging like cancer, Alzheimer's disease, and Parkinson's.

The stability of methylation patterns on DNA samples means the data can be trusted more in the lab when investigating anti-aging interventions.

The GrimAge clock (named for the Grim Reaper) predicts lifespan and healthspan in units of years and tests whether potential lifestyle interventions may slow or reverse biological aging.

In this clip, Dr. Steve Horvath explains the differences between chronological age and biological age.

Sometimes a person's clinical biomarkers doesn't accurately reflect how well they are aging, but epigenetic clocks may give a more reliable insight into their aging.

Evidence indicates that the heritability of epigenetic aging is about 40 percent. This is seen in supercentenarians and their offspring, who tend to age slower than their younger counterparts.

Emerging evidence now suggests that supplemental omega-3 fatty acids or vitamin D slow epigenetic aging.

Choosing how much broccoli or broccoli sprouts to eat is really up to individual tolerance. Isothiocyanates are inherently bitter, and the human body naturally resists the intake of bitter foods. Aiming for 2 to 4 ounces of sprouts per day is a reasonable and healthy goal.
