Mediterranean Diet Linked to Lower Death Risk Across 1.8 Million People
Pooling 54 studies with over 1.8 million participants, each one-point bump on a Mediterranean diet score was linked to a 4% lower risk of dying from any cause. The studies covered diverse populations worldwide, with follow-up periods ranging from 2 to 60 years. Evidence certainty was rated moderate, meaning the association is fairly reliable but not ironclad.
Key Insight
This research suggests closer adherence to Mediterranean-style eating may be associated with longer life.

Eating More Fruits, Fish, Nuts, and Dairy Tied to Slower Cognitive Decline
In over 3,000 Chinese older adults tracked for about five years, those who ate more from six protective food groups (fruits, vegetables, nuts, legumes, fish, and dairy) showed slower cognitive decline. People scoring highest on this diet scale declined about 0.42 points per year slower on a cognitive test compared to those scoring lowest. The effect was modest but consistent across different ways of measuring cognition.
We May Not Be Aging Slower. We're Just Starting Later.
A big question in longevity research is whether rising life expectancy means we're actually aging more slowly. This analysis of mortality data from 12 countries suggests the answer is no. After accounting for historical shocks like wars and pandemics, the rate at which aging accelerates after 80 hasn't changed. The gains in lifespan appear to come from pushing back when serious aging begins, not from slowing the process itself.
Metformin's Anti-Aging Case: Strong Clues but Still No Proof
This review pulls together lab, population, and clinical trial evidence on metformin as a potential aging-slowing drug. At normal doses, metformin seems to flip several key aging switches: boosting cellular cleanup, calming inflammation, and improving energy production. Large population studies link metformin use to lower rates of age-related diseases, even in people without diabetes. However, the review honestly notes that metformin may actually worsen aging in older animals, so the picture is still mixed.
