The Takeaway
Lifespan-extending 'longevity' isn't just in the genes; it can be partially transferred through diet. These specific yeast lipids repair the gut and fix brain mitochondria in fruit flies, suggesting a shortcut to anti-aging that doesn't require genetic mutation.
From the abstract
Aging is marked by a progressive breakdown of intestinal integrity and metabolic homeostasis, which together drive systemic decline in physiology and reduced lifespan. Here, we demonstrate that dietary lipids extracted from a genetically engineered long-lived yeast strain robustly extend lifespan in Drosophila by preserving gut function and modulating the gut brain axis. Using deuterium oxide probed stimulated Raman scattering microscopy, we show that these yeast-derived lipids restore age-relat
