[Compiled Guan Shuping/Comprehensive Report] A British study analyzed the eating habits of 60,000 people and concluded that eating a "Mediterranean diet" that eats more nuts, seafood, whole grains and vegetables can reduce the risk of dementia by nearly 1/ 4.

The research may pave the way for new ways to prevent dementia.

The British "Guardian" reported on the 14th that Janice Ranson, the co-first author of the study and a senior researcher at the University of Exeter's School of Medicine in the UK who studies Alzheimer's disease, said, "This is like a large-scale population. Findings based on research highlight the long-term brain health benefits of a Mediterranean-style diet rich in fruits and vegetables, whole grains, and healthy fats”; The effects are clearly visible.”

This study is based on the data of more than 60,000 people obtained from the database "UK Biobank" with more than 500,000 British people's medical and lifestyle records, to assess the degree of Mediterranean diet of the research subjects, and to consider genetic risk.

During the nearly 10-year study period, 882 people were diagnosed with dementia, but those who followed the Mediterranean diet had a 23 percent lower risk of dementia than those who ate a different diet.

The study was published on the 14th in the journal "BMC Medicine" under the "Modern Biology Publishing Group (BMC)".

Lead author Oliver Shannon, a lecturer in human nutrition and aging at the University of Newcastle, said finding ways to reduce the risk of dementia was a "major priority" in public health. Millions of people around the world live with limited treatment options at this time."

Susan Mitchell, head of policy at Alzheimer's Research UK, which works on Alzheimer's research, agreed the study was "interesting" but needed to be explored further and should be expanded to include different people of ethnic background.

There is no "sure way" to prevent dementia, she said, and there is plenty of evidence that a healthy, balanced diet can help reduce the risk of cognitive decline, "but the evidence for specific dietary patterns is significantly less clear." ".

In addition, a research team from the University of Sydney in Australia published a research report in the BMJ's Heart on the 14th. After analyzing 16 studies, it was found that women who followed a Mediterranean diet more strictly had a higher risk of cardiovascular disease. Other women were 24 percent lower and had a 23 percent lower death rate.

"Washington Post" reported on the 15th that this is the first analysis of the possible association between a Mediterranean diet and cardiovascular disease in women.

However, the researchers acknowledged limitations of the study, including the fact that it was largely observational and relied on self-reported food intake.

Victoria Taylor, a senior nutritionist at the British Heart Foundation who was not involved in the study, said that this type of observational study means that it cannot show the cause and effect, and relies on the self-report of the research subjects, which also affects the reliability of the results in dietary research. common problem.
