Uric acid: What’s optimal? – Michael Lustgarten

Lycopene is found almost exclusively in tomatoes and watermelon. If these foods are related to my increasing levels of uric acid, if I ate less of them, I’d expect to see a corresponding decrease in uric acid. So, in 2019, I ate less of these foods, thereby reducing my average lycopene intake from 11,585 to 9,132 micrograms per day. How did that affect circulating levels of uric acid? In 6 measurements for 2019, my average uric acid level was 4.6 mg/dL, a value that was significantly different (p=0.02) from the 2016-2018 average of 5.2 mg/dL. Whether eating less watermelon and tomatoes caused the decrease is unknown, but it’s good to know that uric acid can be potentially modified with dietary change!

Scientists see inner workings of enzyme telomerase, which plays key roles in aging, cancer: Detailed view of its core may lead to development of targeted drugs -- ScienceDaily

"We're now seeing not just the face of the clock, we're seeing how the components inside interact to make it work," said Juli Feigon, a professor of chemistry and biochemistry in the UCLA College and a senior author of the study. "At each step, we zoom in closer and see more and more details, and can now begin to deduce not just what the enzyme looks like, but also how it functions. Knowing that may lead to the development of new drugs that target specific parts of the enzyme."

Running as a Key Lifestyle Medicine for Longevity. - PubMed - NCBI

Running is a popular and convenient leisure-time physical activity (PA) with a significant impact on longevity. In general, runners have a 25%-40% reduced risk of premature mortality and live approximately 3 years longer than non-runners. Recently, specific questions have emerged regarding the extent of the health benefits of running versus other types of PA, and perhaps more critically, whether there are diminishing returns on health and mortality outcomes with higher amounts of running. This review details the findings surrounding the impact of running on various health outcomes and premature mortality, highlights plausible underlying mechanisms linking running with chronic disease prevention and longevity, identifies the estimated additional life expectancy among runners and other active individuals, and discusses whether there is adequate evidence to suggest that longevity benefits are attenuated with higher doses of running.
