Mediterranean Diet Boosts Women's Lifespan by 23%, Study Finds

A new study published in JAMA Network Open found that women adhering to a Mediterranean diet, which includes high consumption of olive oil, fruits, fish, nuts, and vegetables, and low consumption of red meat and sweets, have a 23% reduced risk of all-cause mortality over 25 years. Factors like inflammation, insulin resistance, and body mass index partly explain this benefit, though much remains unexplained. Previous research also suggests the diet may reduce dementia risk.
