A recent study published in The Journals of Gernontology Series A found an association between poor oral health and frailty in the elderly. T he study found that elderly people who had poor status in 3 or more measures of oral frailty(# of natural teeth, chewing ability, tongue pressure, difficulties in eating or swallowing, and … Continue reading Oral health, chronic disease, and longevity
As research in to human aging and the mechanisms behind it grow, there's a need to address the big fat albatross around the neck of gerontology. The albatross is that until we identify some valid biomarkers of human aging, we must rely on the data in animal models and epidemiological research in humans. Currently, there … Continue reading Aging Biomarkers: Am I 7 years older or 10 years younger?
A study recently published in the journal Cell is teeming with incredible insights in to how/why our microbiome evolves with us as we age. There are quite a few key takeaways from this study, which is open access and free to read here. While focus has been on the gut microbiome, other microbial communities throughout … Continue reading A comprehensive review of your aging and evolving gut microbiome
A study I posted recently on the Facebook page generated a decent discussion on how traumatic brain injury promotes a leaky gut. The interesting take-home message from the study is that one long term symptom of traumatic brain injury(TBI) is "leaky gut". The theoretical trek from there is that endotoxin can then cross the gut … Continue reading Could sealing the blood brain barrier and gut really be this easy?
If it seems as though research in to aging is exploding right now, that's because it is. Over the last few decades, our paradigm on aging has experienced a pretty substantial shift. What was once believed to be an inevitable process dictated solely on the passage of time and the genetic hand you've been dealt … Continue reading Healthy aging requires proper circadian rhythms
As you're probably aware by now, I fancy myself a test subject in my own longevity experiment. I got my degree in science, I spent 6 years in clinical research at the University of Pennsylvania, and 99.9% of everything I read is either science or science-related. One of the biggest things we need in science … Continue reading Longevity is about more than just aging biomarkers
It's almost dogma in longevity research that caloric restriction will extend your lifespan. Granted, I think everyone agrees that humans won't see the same level of life extension under caloric restriction as mice, primarily because we experience a slower rate of epigenetic drift. It's also unlikely, although still plausible, that humans will spend a large … Continue reading The shocking reasons why calorie restriction may not prolong your life
Calorie restriction and fasting are 2 of the hottest areas of research in longevity and age rejuvenation. In fact, you probably know someone who has dabbled in, or who is currently dabbling in, one or the other. These techniques, whether you're talking about calorie restriction, fasting, or protein restriction, fall under the general umbrella of … Continue reading Is there a simpler alternative to calorie restriction for longevity?
The vast majority of people define aging as the passing of time, irrespective of anything else. For most, aging is an inevitable part of life. Few realize that there are examples of life on the planet that don't age, and one that's considered immortal. Part of the problem is that people conflate aging with death. … Continue reading The test that could help transform your health
Readers of this blog know that I take a non-conventional approach to gut health. While I feel that focusing on what goes in to the gut is important for gut health, it's not the only kid on the block. Over the last few blogs I've discussed how factors in the blood play a big role … Continue reading The NAD World: how fasting promotes healthy aging
