Does cocoa improve Alzheimer’s disease?
Information about food and the effects of cocoa on improving Alzheimer’s and how much a cup of cocoa increases brain blood flow in elderly people.
This research was conducted on sixty elderly people and its results were published in Neurology.
The researchers divided the study subjects into two groups, one group was given cocoa with high flavonol and the other group was given cocoa with low flavonol, and they were asked not to consume any other type of chocolate during the day.
Although these people were healthy, the examinations before the research showed that 17 of them had decreased blood supply to the brain, and only 37% of them did not have any problems with cerebral blood supply.
After the end of the research, the researchers noticed that regardless of what type of cocoa was drunk, blood flow to the brain improved in 88% of people, and those who had cognitive problems such as memory loss showed improvement.
Farzaneh Survand, a researcher of this research from Harvard Medical School, says that different parts of the brain need energy to complete their activities, and this means they need more blood. For this reason, this relationship is called neurovascular and plays an important role in diseases such as Alzheimer’s.
The researchers say that there is no difference between low and high flavonols because either a small amount of the substance is enough to have an effect or because other substances in the drinks had the same effect.
However, it is still too early to draw a definitive conclusion.
Dr Simon Riley, director of research at the Alzheimer’s Association UK, said: “Cocoa treatment is likely to become a popular treatment but it is too early to say for sure.”
However, “unhealthy brain vessels are one of the risk factors for dementia, so a better understanding of the impact of vascular problems on the loss of brain activity can help research in the field of treatment and prevention.”
