Researchers at USC have found that olive oil, fish, and legumes are among the foods most closely tied to elevated levels of these mitochondrial microproteins, both linked to cardiovascular resilience and protection against cognitive decline. The discovery does not merely add another chapter to the long story of the Mediterranean diet's benefits — it begi
