Good for memory: Flavonoids are found in foods like kale, beans, tea, spinach and broccoli

People who eat or drink food with antioxidant flavonols can try one slower rate of memory decline, according to a study published in the medical journal Neurology. An estimated 6.5 million Americans age 65 and older are living with Alzheimer’s.

The study, conducted by researchers at Rush University Medical Center in Chicago, involved 961 people without dementia with an average age of 81.

Participants completed a questionnaire about how often they ate specific foods each year, for an average of seven years, in addition to completing cognitive and memory tests.

While the average intake of antioxidant flavonols — a compound found in plant pigments — for the average American is around 16 mg to 20 mg per day, the study population average was around 10 mg.

The researchers found that the average cognitive score of people with the highest intake of flavonols declined more slowly than the average score of the group with the lowest intake.

The flavonol kaempferol was found to be the most effective. It is found in foods like kale, beans, tea, spinach and broccoli.

Thomas Holland, co-author of the study, suggests that while the study “shows that making specific food choices can lead to a slower rate of cognitive decline,” it does not fully prove the connection between consuming antioxidant flavonols and slowing down the pace of cognitive decline. cognitive decline.

Scientists continue to research and debate the cause of cognitive disorders like Alzheimer’s and whether specific factors could affect cognitive decline. Recently, the clinical trial of a new drug suggested a possible treatment to delay cognitive abilities, although its results were not conclusive. The National Institute on Aging suggests that increasing physical activity, maintaining healthy blood pressure, and practicing cognitive skills such as memory, reasoning, or processing speed can lead to slower rates of cognitive decline.

Alzheimer’s research (specifically detection) is a popular focus for billionaires like Jeff Bezos, Bill Gates and Ronald Lauder, who have spent millions on “risk philanthropy”, where the financial returns from their investments in groups like Alzheimer’s Drug Discovery Foundation are invested goes back to the foundation, not back to the donors.
