Study reveals vegan diet may reduce biological age in just eight weeks

Plant-based diet was associated with changes in gene expression, specifically through a process called DNA methylation, which can “turn off” or “silence” genes without altering the DNA itself.

Study reveals vegan diet may reduce biological age in just eight weeks

GOING vegan for eight weeks was found to be linked to a reduction in biological age, according to a study published in the journal BioMed Central (BMC) Medicine.

The research examined the molecular effects of a plant-based diet, which excludes animal products like dairy and primarily consists of fruits, vegetables, grains, beans, and nuts.


Researchers from Stanford University, US, discovered that this diet was associated with changes in gene expression, specifically through a process called DNA methylation, which can "turn off" or "silence" genes without altering the DNA itself.

Higher levels of DNA methylation are linked to a higher biological age, an epigenetic process that affects gene behaviour by modifying its environment.

For eight weeks, the team followed 21 pairs of adult identical twins – one half of each pair consumed an omnivorous diet, including meat, eggs and dairy, while the other consumed a vegan one. Identical twins share a significant amount of their genetic makeup.

On average, the participants were aged 40 years and had a body mass index (BMI) in the overweight category. About 77 per cent of the group were women.

After eight weeks, the researchers observed a 'younger' heart, liver, inflammatory and metabolic system among the participants consuming the vegan diet. These changes were not seen in those eating the omnivorous diet.

However, the authors cautioned that the extent to which these changes could be attributed to their diets was unclear.

They noted that on average, the individuals on the vegan diet lost two kilograms more compared to those on the omnivorous diet.

The results suggest that the weight loss could have contributed to lowering of the biological age in the vegan group, the researchers said.

Reacting to the study, Tom Sanders, a professor emeritus of Nutrition and Dietetics at King's College London, and not involved in the study, said that the findings might be favourable for vegans in terms of ageing.

However, the diet can come with micronutrient deficiencies, which often take years to exert harmful effects, Sanders said.

"For example, unless a vegan diet is supplemented with vitamin B12 they develop vitamin B12 deficiency that causes chronic and often insidious damage to the nervous system," Sanders said.

Long-term studies of vegans also find adverse effects on bone density, probably caused by very low calcium and barely adequate protein intakes, Sanders said. (PTI)

New Covid strain Stratus spreads in UK with unusual hoarse voice symptom

Key points

  • A new Covid strain known as Stratus is spreading across the UK
  • The variant is marked by a distinctive symptom: a hoarse or raspy voice
  • Sub-variants XFG and XFG.3 now account for 30% of cases in England
  • Experts say there is no evidence of more severe disease
  • Lower immunity levels may make more people vulnerable to infection

Covid variant Stratus on the rise in the UK

A new strain of Covid-19, known as Stratus, is spreading across the UK and drawing attention for its unusual symptom — a hoarse or raspy voice. According to data from the UK Health Security Agency (UKHSA), Stratus and its two sub-variants, XFG and XFG.3, are responsible for around 30 per cent of Covid cases in England.

Of the two, XFG.3 is currently the more dominant. The UKHSA confirmed that monitoring of all circulating Covid-19 variants is ongoing as part of regular surveillance.

Human brain continues forming neurons well into old age, study finds

Key points

  • New neurons continue forming in the brain’s hippocampus into old age
  • Study confirms presence of neural progenitor cells in adults
  • DNA carbon dating and single-nucleus RNA sequencing were used
  • Research shows variation in neuron production between individuals
  • Findings could aid treatments for neurodegenerative and psychiatric disorders

Human brain shows ongoing neuron formation into older age

A new study has confirmed that the human brain continues to produce new nerve cells well into late adulthood, challenging previous assumptions about age-related decline in neurogenesis. The findings, published in the journal Science, provide fresh insight into how adaptable the brain remains over a lifetime.

Neurogenesis, the process by which new neurons form in the brain, is known to occur in the hippocampus — a region involved in memory. While previous research has suggested that this process continues throughout life, there has been limited concrete evidence of the presence of neural progenitor cells in the adult brain.

Sri Aurobindo

Heehs’s biography is grounded in extensive archival research across France, England, India and Israel

Sri Aurobindo and the rise of the Asian century

My friend and colleague, the American historian Peter Heehs, who has lived in Pondicherry, India, for decades, recently published a compelling new biography, The Mother: A Life of Sri Aurobindo’s Collaborator (2025). Heehs previously authored The Lives of Sri Aurobindo (2008), which remains one of the most balanced and scholarly accounts of Aurobindo’s life.

According to Heehs, most previous biographies of the Mother were written for devotees and relied on secondary sources, often presenting her as a divine incarnation without critical engagement. “Such biographies are fine for those who see the Mother as a divine being,” Heehs said, “but they can be off-putting for readers who simply want to understand her life – as an artist, writer, spiritual teacher, and founder of the Ashram and Auroville.”
