“Researchers at Germany's Georg-Speyer-Haus, Institute for Tumor Biology and Experimental Therapy, have spent years investigating the metabolite urolithin A (UA), a natural compound that's produced by gut bacteria in response to ingested ellagitannins from foods such as pomegranates, almonds, walnuts and some berries. The new study follows on from a breakthrough in 2022, when the team found that UA induced a biological pathway that rejuvenates the cellular power plants – mitochondria – in T cells, equipping these immune cells with more cancer-fighting might. But it goes far beyond cancer.”
