“Coffee contains a number of compounds with antioxidant properties, and previous research has shown that coffee and coffee extracts may reduce DNA damage in colon cells and white blood cells. Findings of this randomized controlled trial detail the effects of daily coffee consumption on DNA damage in healthy adults.”

“If larger, longer trials confirm the observed signal, melatonin could become a targeted way to support DNA damage cleanup in shift workers. In Q&A #54, I discuss melatonin's antioxidant properties and whether it has therapeutic potential beyond its role in promoting sleep.”

“Earlier studies found that a pollutant in coal plant emissions called polycyclic aromatic hydrocarbons (PAHs), was able to damage DNA in infants but that this occurred at lower levels in the cohort of babies born after the plant had shut down, indicating less exposure.”

“Consumption of dark roast coffee brew (500 ml/day) for 1 month caused a 23% reduction in DNA damage in white blood cells compared to baseline levels. DNA damage is known to accelerate the aging process and can lead to cancer (randomized controlled trial).”

“Randomized controlled trial finds that reducing food intake lowered metabolic rate during sleep by 10% and reduced DNA damage, a biomarker for aging, by 20% in healthy adults. DNA damage accumulates with age and plays a role in cancer, stem cell dysfunction, and more.”

“The damage could be repaired by two days of catch-up sleep. DNA repair enzymes were significantly decreased in sleep-deprived animals. This is no surprise because repair mechanisms occur during sleep.”

“Aging NAD+ depletion may drive the hallmarks of aging, including decreased autophagy, increased DNA damage, increased mitochondrial dysfunction, and dysregulated nutrient sensing. Depletion of NAD+ may predispose organisms to various age-related diseases, including neurodegenerative diseases, metabolic diseases, and cancer.”

“This process of rapid expansion followed by programmed senescence and clearance is necessary for quick healing without increasing cancer risk. Arresting growth of stressed, damaged cells DNA damage and mitochondrial dysfunction are the primary drivers of cellular senescence due to aging.”

“Cellular checkpoints and DNA damage-response pathways help preserve genomic stability and cell-cycle progression, but these processes decline with aging. Detecting genomic instability with gamma-H2AX There are five known histone proteins: H1, H2A, H2B, H3, and H4.”

“They found that exposure to 10 micromolar BBP induced considerable cellular disruption, increasing germ cell apoptosis, abnormalities in chromosome structure, and elevated levels of DNA damage throughout the reproductive tissues.”
