Mediterranean diet likely to lower brain damage risk

New York, Feb 9 (IANS)A Mediterranean diet may help people avoid the small areas of brain damage that can lead to problems with thinking and memory, says a new study.

The study found that people who ate a Mediterranean-like diet were less likely to have brain infarcts, or small areas of dead tissue linked to thinking problems.

The diet includes high intake of vegetables, legumes, fruits, cereals, fish and monounsaturated fatty acids such as olive oil; low intake of saturated fatty acids, dairy products, meat and poultry; and mild to moderate amounts of alcohol.

Researchers assessed the diets of 712 people in New York and divided them into three groups based on how closely they were following the Mediterranean diet.

Then they conducted MRI brain scans of the people an average of six years later. A total of 238 people had at least one area of brain damage.

Those who were most closely following a Mediterranean-like diet were 36 percent less likely to have areas of brain damage than those who were least following the diet.

Those moderately following the diet were 21 percent less likely to have brain damage than the lowest group.

"The relationship between this type of brain damage and the Mediterranean diet was comparable with that of high blood pressure," said study author Nikolaos Scarmeas, Columbia University Medical Centre (CUMC) and a neurologist.

"In this study, not eating a Mediterranean-like diet had about the same effect on the brain as having high blood pressure," Scarmeas said, according to a university release.

The study will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17.
