Summary of Key Findings This paper reports on a 20-year study examining whether regular sardine consumption affects longevity and reduces gender gaps in life expectancy. The study tracked 400 participants (200 Portuguese and 200 Portuguese-Canadians) who consumed sardines every other day for 10 years. Study Design and Participants Key Results After 10 Years Theoretical Background […]
Key Findings A 2023 study from China Agricultural University demonstrated that dietary genistein supplementation significantly extends both healthspan and lifespan in mice through gut microbiome modifications. Longevity Benefits Mechanism of Action Gut Microbiome Changes: Fecal Transplant Validation: Study Design Genistein Sources and Background Genistein is found in leguminous plants, particularly soybeans and coffee beans.

Main Findings This prospective study provides the first evidence that higher dietary spermidine intake significantly reduces all-cause mortality in humans. The research demonstrates a strong dose-response relationship, with participants in the highest tertile of spermidine consumption showing mortality risks equivalent to being 5.7 years younger. Study Design and Population Primary Cohort: Bruneck Study Validation Cohort:

Main Finding The longevity drug 17α-estradiol (17αE2) provides greater protection against aging-related decline in male mice carrying the APOE4 gene variant compared to APOE3 mice. APOE4 is associated with shorter lifespan and higher Alzheimer’s disease risk, but 17αE2 treatment largely reverses these negative effects. Key Results Aging Markers Metabolic Improvements Brain Function Molecular Changes Study

TL;DR: A 2024 Nature study shows that inhibiting interleukin-11 (IL-11) extends median mouse lifespan by 28.7% when administered at an age equivalent to human late-50s, with improved health markers and reduced tumor incidence. This extension rivals that seen with rapamycin, raising questions about whether IL-11 inhibition works through similar or complementary mechanisms. Key Findings Lifespan
TL;DR: A large-scale mouse study (n=960) found that both fasting and calorie restriction (CR) extended lifespan, with 40% CR showing the most dramatic results (36% increase in median lifespan). The 40% CR group also maintained youthful physical activity levels throughout life. Key biomarkers like lymphocyte count and red blood cell distribution width (RDW) strongly predicted
