The Mediterranean diet known as the’best diet’. While there are many people who enjoy eating it while thinking about their health, it has been shown that eating junk food or processed food such as hamburgers and pizza at the same time can reduce brain function.
It is said that the beneficial effects of a healthy diet can be reduced for those who eat a’parallel diet’ with the mind that it would be okay to eat hamburgers or pizza once after eating steadily.
The research team at the Rush University Medical Center in the United States conducted a study on 5,000 people aged 65 or older living in Chicago. All participants completed a cognitive assessment questionnaire that assessed basic information processing skills and memory, and a questionnaire about how often they consumed 144 foods.
Among the 144 foods, the Mediterranean diet included fruits, vegetables, legumes, olive oil, fish, potatoes, and moderate amounts of wine, while the Western diet included fried foods, refined grains, sweets such as candy, red meat, processed meat, and whole dairy products. , Pizza, hamburgers, junk food and processed foods were listed. Each of these foods was scored from 0 to 55.
The researchers then reviewed the association between the participants’ overall cognitive function, episodic memory capacity, and perceptual speed, as well as the Mediterranean diet score.
As a result of taking into account other potential variables such as age, sex, race, education level, smoking, body mass index, cardiovascular disease, etc., participants who followed the Mediterranean diet had a reduced rate of cognitive decline during the study period. Participants with a higher Mediterranean diet score were found to be 5.8 years younger in cognitive ability compared to those with the lowest score.
On the other hand, participants who ate more of a Western diet, mainly junk food, had no cognitive benefit, even with a Mediterranean diet, and accelerated brain aging.
The researchers said, “As a result of this study, it was found that the benefits of the original Mediterranean diet decreased when Western-style diets such as pizza, hamburgers, and processed foods were added during the Mediterranean diet.” As it is known that eating refined grains promotes inflammation and cognitive decline in old age, it is recommended to eat more green leafy vegetables, berries, olive oil, and fish.”
The Mediterranean diet is a diet that is popular in Italy and Greece adjacent to the Mediterranean Sea. It is a healthy diet that eats a lot of fruits and fish and limits sugar, dairy products, and processed meats. It was selected as the best diet of the year by the US News & World Report for 3 consecutive years.
Meanwhile, the results of this study were published in the journal’Alzheimer’s & Dementia’.
