Food DNA
A study published in the American Journal of Clinical Nutrition examined the relationship between diet quality and epigenetic aging clocks [1]. This study used data from the Framingham Heart Study Offspring Cohort. This specific study noted the Dietary Approaches to Stop Hypertension (DASH) scores, which are derived from a food frequency questionnaire (FFQ), of 1,995...
Olives
Researchers publishing in Aging Cell have discovered how and why oleuropein (OLP), a polyphenol derived from olives, ameliorates epigenetic kidney aging. KidneyThe kidney's main function is to filter waste products out of the blood and deliver the resulting urine to the bladder. The functional unit of the kidney is called the nephron, and each kidney...
Backwards Clock
A commercially available alpha-ketoglutarate-based supplement has been shown to roll back biological age by 7 years on average in a retrospective human study [1]. Live slower, die later Though metformin and rapamycin are getting most of the attention in the longevity field today, alpha-ketoglutarate (AKG) has emerged as another candidate longevity drug. These three molecules have...
Stressful stimuli
Researchers publishing in Aging have found that stresses, both biological and in daily life, harm one of our fundamental abilities to correctly process what's going on around us. What is sensory gating? Sensory gating is the brain's ability to filter out irrelevant stimuli after the first time it experiences them. It reflects our ability to...
Mice playing
A study published in Nature Communications has shown that an environment rich in stimuli changes the epigenetics of the mouse hippocampus, making the brains of aged mice more like those of young mice [1]. What is an enriched environment? For mice, enriched environments (ENRs) are "large cages equipped with frequently rearranged toys, providing physical, cognitive,...
Magnifying glass on cancer
Biotech company GRAIL made history earlier this month when it introduced the first commercially available multi-cancer blood test. The test is based on analyzing tumor DNA in circulation and could be a game-changer in the field of cancer diagnostics, especially if the company continues to improve it. Discovering cancer early Medicine has made great strides...
