Research conducted by Rush University Medical Center in Chicago suggests that taking Tea and Wine slows down memory deterioration
Flavonols belong to a group of natural substances known as flavonoids, which are found in various foods such as fruits, vegetables, grains, tea, and wine.
These natural compounds have gained attention due to their health benefits and are considered essential in various nutraceutical, pharmacological, therapeutic, and cosmetic applications.
The study highlights the potential importance of including flavonol-rich foods in one’s diet to support cognitive health and potentially mitigate memory decline over time.
Further research is likely needed to better understand the specific mechanisms through which flavonols exert their effects on memory and cognitive function, as well as to confirm these findings in larger and more diverse populations.

The number of Subjects was 961 people with an age average of 81
The study included 961 participants with an average age of 81 and without dementia. They were asked about their food consumption habits and underwent yearly cognitive and memory tests for an average of seven years.
Participants were also asked about their education level, exercise habits, and engagement in mentally stimulating activities like reading and playing games.
The subjects were divided into five groups based on their flavonoid intake levels. The average daily intake of total flavonols was around 10 mg, with the highest group consuming approximately 15 mg per day and the lowest group around 5 mg per day.
The research team used an overall global cognition score derived from 19 cognitive tests to measure rates of cognitive decline. Scores ranged from 0.5 for those without cognitive issues to -0.5 for those with Alzheimer’s disease.
Results showed that participants with the highest flavonol intake experienced cognitive decline at a pace of 0.4 units per decade slower than those with the lowest intake, even after adjusting for other factors like age, sex, and smoking.
Thomas M. Holland, MD, MS, from Rush University Medical Center, suggests that the observed cognitive benefits of flavonols may be attributed to their inherent anti-inflammatory and antioxidant properties.

link between higher amounts of flavonols and slower cognitive decline
The study found a connection between higher flavonol intake and slower cognitive decline. Flavonols were broken down into four constituents: kaempferol, quercetin, myricetin, and isorhamnetin.
The top food sources for each flavonol constituent were identified: kale, beans, tea, spinach, and broccoli for kaempferol; tomatoes, kale, apples, and tea for quercetin; tea, wine, kale, oranges, and tomatoes for myricetin; and pears, olive oil, wine, and tomato sauce for isorhamnetin.
The study suggests that consuming more fruits, vegetables, and tea may help in maintaining brain health and slowing cognitive decline.
However, the study does not prove a direct causal relationship between flavonols and cognitive decline. Further research is needed to establish causation.
A limitation of the study was that dietary information was self-reported through a food frequency questionnaire, which may introduce inaccuracies in reporting.
The findings were published in the journal Neurology on November 22, 2022.
Conclusion: Tea and Wine slows down memory deterioration
Examining four key constituents of flavonols and identifying their top food sources, such as kale, tea, and wine, the study suggests that simple dietary adjustments could potentially contribute to maintaining brain health.
However, it’s important to note that while the findings are significant, they do not establish a direct cause-and-effect relationship between flavonol consumption and cognitive decline. Additionally, the reliance on self-reported dietary data presents a limitation in the study’s methodology.
Nevertheless, these findings underscore the potential benefits of incorporating flavonol-rich foods into one’s diet as part of a proactive approach to cognitive health. Further research is warranted to explore the underlying mechanisms and confirm these associations, ultimately offering valuable insights for promoting healthy aging and cognitive function.
