Education Gap Is Speeding Up Aging in Millions of People

A new study reveals that Americans with less education are aging faster than those with more schooling, and the divide has widened over the past three decades. Biological age—measuring internal health rather than years lived—shows that people with a college degree experience slower aging.

How Fast Your Brain Ages Could Determine Your Future Health

A new study reveals that our organs age at different speeds, and those differences can predict future disease risk and even life expectancy. Using blood-based protein signatures from over 44,000 participants, researchers developed an algorithm to estimate the biological age of 11 organ systems.

Vitamin D May Slow Biological Aging

New results from the VITAL randomized trial show that daily vitamin D3 supplementation helps preserve telomere length in older adults, potentially slowing a key biological aging process. Telomeres are protective caps on chromosomes that shorten with age and are associated with chronic diseases.

Unhealthy Diet Linked to Faster Biological Aging in Young Adults

Diets high in processed meat, fast food, and sugary drinks accelerate biological aging, even in young adults. Researchers measured biological age using epigenetic clocks, which track gene regulation changes over time. Participants with a diet rich in fruits and vegetables showed slower aging, suggesting dietary choices influence how quickly the body ages.

Faster Biological Aging Linked to Ultra-Processed Foods

Ultra-processed foods are linked to accelerated biological aging, as confirmed in a study analyzing over 22,000 people. Researchers found that these foods, high in additives and preservatives, speed up the body’s internal aging clock, independently of nutritional quality.

Ancient DNA Markers Predict Aging with New Epigenetic Clock

Researchers have developed an epigenetic clock, "Retro-Age," that predicts biological age by analyzing DNA markers from ancient viral remnants in the human genome. This study highlights how the reactivation of these retroelements, such as HERVs and LINEs, impacts aging, inflammation, and genomic stability. The findings suggest that monitoring these markers could guide anti-aging therapies and improve health outcomes, particularly in conditions like HIV. The research also opens avenues for exploring treatments that may reverse the biological effects of aging.

Eight Week Vegan Diet Lowers Biological Age

A new study reveals that an eight-week vegan diet can reduce biological age estimations based on DNA methylation levels. The study, involving 21 pairs of adult identical twins, found that participants on a vegan diet showed decreases in biological age and the ages of their heart, hormone, liver, inflammatory, and metabolic systems.

Grief Accelerates Biological Aging

Losing a close family member can accelerate biological aging, according to a new study. Researchers found that people who experienced the loss of a parent, partner, sibling, or child showed signs of older biological age. This effect was measured using DNA markers known as epigenetic clocks. The study underscores the long-term health impacts of grief and loss across the lifespan.

Heart-Healthy Habits Linked to Reduced Biological Age

A new study reveals that heart-healthy behaviors can reduce biological aging. Researchers found that managing heart disease risk factors is associated with a younger biological age and lower risk of heart disease, stroke, and death. The study highlights the role of DNA methylation in linking cardiovascular health to biological aging.

Depression and Anxiety Linked to Accelerated Biological Aging in Adults

Adults with advanced biological age are at a higher risk of depression and anxiety, according to a study that found participants with older biological age were 6% more likely to develop these mental health conditions at the 8.7-year follow-up compared to those who tested younger biologically.

Bodies of People With Mental Illness Are Biologically Older Than Their Actual Age

People with a long-term history of mental illness, including bipolar disorder and anxiety disorders, have blood biomarkers that reflect increased biological aging. The findings may help explain why those with mental health disorders tend to have shorter life spans and are more prone to age-related diseases than the general population.

Overactive Cell Metabolism Linked to Biological Aging

Human cells with impaired mitochondria expend more energy. While this hypermetabolism enhances a cell's short-term survival, it also dramatically increases the rate at which the cell ages.
