American researchers have identified certain foods and beverages that can slow down memory decline in older adults.
According to a study by the American Academy of Neurology, those who consume foods and drinks high in flavonols are less likely to report forgetfulness.
Flavonols are antioxidant compounds found in plants that help combat dementia, a condition where the brain struggles to perform its usual functions, particularly in its most common form—Alzheimer’s disease.
These flavonols, which can be found in plant pigments, have long been recognized for their health benefits. Researchers have determined that these phytochemicals may help prevent the development of cardiovascular diseases, diabetes, and cancer. Scientists also link flavonols to the prevention of brain diseases.
A recent study on this topic was conducted by the Rush University Medical Center in Chicago, USA. It specifically showed that among the foods and drinks rich in flavonols that help preserve memory over the years, wine and tea hold a prominent place. When it comes to wine, red wine contains the highest levels of flavonols. As for tea, all varieties boast these beneficial compounds.
Researchers noted that adult Americans consume an average of 16 to 20 milligrams of flavonols per day.
Thomas Holland, the lead author of the study, confirmed that following a specific diet can contribute to a slower decline in cognitive functions. The scientist’s advice is quite simple: eat more fruits and vegetables and drink more tea. This will help maintain brain health, as reported by Newsweek. The researcher pointed out that among the foods with such miraculous properties are red wine, tomatoes, apples, and tea.
Wine and tea – the new favorites for good memory
Scientists reached this conclusion after a seven-year study involving 961 volunteers who showed no signs of dementia. The average age of the participants was 81 years.
The researchers divided the volunteers into five groups based on their flavonol intake. They also regularly asked participants to detail how often they consumed certain foods. Concurrently, cognitive memory tests were conducted. Participants were asked to recall words and numbers and arrange them in the correct order. It is important to note that during the experiment, factors such as gender, education level, lifestyle, and physical activity of the volunteers were taken into account.
The scientists found that those who consumed the most flavonol-rich foods experienced a significantly slower decline in cognitive functions compared to those who consumed the least.
Based on their observations, the researchers compiled a list of foods that effectively slowed cognitive decline. This list includes: kale, beans, tea, spinach, broccoli, tomatoes, apples, wine, oranges, pears, olive oil, and tomato sauce.
This result, according to the scientists, is linked to the antioxidants and anti-inflammatory compounds found in these foods.
While the study showed that tea and wine actively contribute to memory preservation in older age, it is important to consider other aspects of these beverages. Specifically, the significant caffeine content in tea, which can provoke nervous system disorders and increased heart rate, as well as the harmful effects of excessive alcohol consumption, which can lead to memory loss and the development of dementia.
