Science Daily (Feb. 9, 2010) — A Mediterranean diet may help people avoid the small areas of brain damage that can lead to problems with thinking and memory, according to a study that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17, 2010.

Balancing Protein Intake, Not Cutting Calories, May Be Key to Long Life

From Science Daily:

Science Daily (Dec. 6, 2009) — Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests.

The research may help explain why 'dietary restriction' (also known as calorie restriction) -- reducing food intake whilst maintaining sufficient quantities of vitamins, minerals and other important nutrients -- appears to have health benefits. In many organisms, such as the fruit fly (drosophila), mice, rats and the Rhesus monkey, these benefits include living longer. Evidence suggests that dietary restriction can have health benefits for humans, too, though it is unclear whether it can increase longevity.

Why A Low-Calorie Diet Extends Lifespans: Critical Enzyme Pair Identified

From Science Daily:

ScienceDaily (June 28, 2009) — Experiment after experiment confirms that a diet on the brink of starvation expands lifespan in mice and many other species. But the molecular mechanism that links nutrition and survival is still poorly understood. Now, researchers at the Salk Institute for Biological Studies have identified a pivotal role for two enzymes that work together to determine the health benefits of diet restriction.

When lacking one enzyme or the other, roundworms kept on a severely calorie-restricted diet no longer live past their normal lifespan, they report in the June 24, 2009, advance online edition of the journal Nature.

Longer Life Linked To Specific Foods In Mediterranean Diet

From Science Daily:

ScienceDaily (June 24, 2009) — Some food groups in the Mediterranean diet are more important than others in promoting health and longer life according to new research published on the British Medical Journal website.

Eating more vegetables, fruits, nuts, pulses and olive oil, and drinking moderate amounts of alcohol, while not consuming a lot of meat or excessive amounts of alcohol is linked to people living longer.

However, the study also claims, that following a Mediterranean diet high in fish, seafood and cereals and low in dairy products were not indicators of longevity.
