Study finds less damage to brain tissue when the regimen is followed,,
MONDAY, Feb. 8 (HealthDay News) -- Eating a Mediterranean-style diet -- one rich in olive oil, whole grains, fish and fruit -- may protect aging brains from damage linked to cognitive problems, a new study finds
Other studies have already found that such diets also lower risks for depression, cancer, heart disease and premature death.
The latest study was led by Dr. Nikolaos Scarmeas, an associate professor of neurology at Columbia University Medical Center, New York City, and involved 712 men and women averaging 80 years of age. All of the participants had no history of stroke and received MRIs to look for brain infarcts -- tissues that have died because of reduced or cut-off blood supply.
Though the infarcts are true strokes, Scarmeas said, they are so small that they escape notice.
In all, 238 people had at least one area of brain damage, he said.
The researchers also looked at how well the participants had followed a Mediterranean-style diet for the six years before the MRI.
"What we found was, those people who were following a healthier diet, more Mediterranean-like, had fewer brain infarcts, strokes, on the MRI," Scarmeas said. Their risk for having such damage was lowered by up to 36 percent, he said.
The reduced risk was linked to the type of diet eaten, the study found. "We broke the diet adherence into three groups: those who adhered very, very little [to the Mediterranean plan], those who adhered to a moderate degree and those adhering to a high degree," he said.
People in the middle -- those who followed the diet moderately well -- were 21 percent less likely to have brain damage than people in the lowest adherence group. Those who followed it most closely had a 36 percent reduced risk compared with those who followed it the least.
