In the video below, Steve Hill from Lifespan.io and I talk about findings from a recent paper (https://content.iospress.com/articles/journal-of-alzheimers-disease/jad200306) that supports a role for the gut microbiome on Alxheimer’s disease. Check it out!
Meta-analysis for the association between HDL with all-cause mortality risk has identified HDL levels 55 – 60 mg/dL range as optimal. However, that data includes subjects up to 85y-in the video, I present data for 85y – 115yr olds that additionally suggests HDL in the 55 – 60 mg/dL range as optimal. In addition, I show my own HDL data over the past 15 years (n=34), the correlation for HDL with my diet, and how I plan on consistently increasing my 15-year average HDL of ~44 mg/dL to the 50’s.
Animal products, including meat, cheese, and eggs contain carnitine and choline, metabolites that are converted by gut bacteria into TMA, which is then converted by the liver into TMAO. Plasma levels of TMAO are associated with an increased risk of disease and death, so should we limit intake of these animal products? Separately, fish contains relatively high levels of TMAO, and blood levels of TMAO spike after fish consumption, but there is a decreased all-cause mortality risk for fish consumers. To explain these disparate findings, other factors may be involved in the TMAO-health and disease story. In the video, I discuss the impact of kidney function on plasma levels of TMAO, disease and mortality risk.
A reduced mortality risk and an increased lifespan has been reported for people who have APOE2 alleles, when compared with APOE3 or APOE4, but beyond associations, data for lifespan in APOE-expressing mice was recently reported, evidence that supports a causative role for APOE on longevity.
My latest blood test results are in-how’s my biological age?
In the video I discuss my dietary approach prior to my latest blood test, the blood test results, and my plan to improve them with diet going forward.
