A systematic review published in Nutrition Reviews on November 2, 2026, examined 11 human studies from Europe, the United States and the Middle East and found Mediterranean-style eating associated with healthier aging. The review reported improved memory, greater physical strength and reduced frailty among people following the diet.
Why it matters
Mediterranean-style eating emphasizes plant-based foods, healthy fats and fiber while limiting red meat, processed foods and added sugar, and its nutrients have antioxidant and anti-inflammatory properties. The findings add to evidence that everyday dietary patterns may influence how people age, a question of growing importance as populations grow older worldwide.
The review drew on 11 human studies, and the DIRECT PLUS trial recorded an average 8.9-month favorable difference between observed and expected biological age, estimated from blood tests detecting chemical changes in DNA. Whether the polyphenol-rich Green-MED variation adds benefit over other Mediterranean approaches remains unresolved.
The players
Nutrition Reviews
Nutrition Reviews is a peer-reviewed scientific journal that publishes systematic reviews and evidence summaries on nutrition science.
The details
In the one-year NU-AGE trial, older adults following Mediterranean-style eating showed reduced inflammation, improved handgrip strength and gains on certain memory measures. Older men with stronger adherence had lower odds of frailty, and a nine-year U.S. study associated greater adherence with slower memory decline.

Health Landscape
The review builds on the NU-AGE trial, a one-year European study that tracked older adults following Mediterranean-style eating, and extends its findings on inflammation and handgrip strength across a wider body of research. Its biological-age results add a new measure to the ongoing effort to assess whether dietary patterns can slow aspects of aging.
Readers who want the benefits linked to aging can add olive oil, nuts, legumes and vegetables to their meals while cutting back on red meat, processed foods and added sugar. The review does not establish that any single food or supplement produces these effects on its own.
The takeaway
Shifting toward a Mediterranean-style pattern of plant foods, healthy fats and fiber may support memory, strength and resilience as people age. Consistent everyday habits appear more useful than any single food or variation.
