Antioxidant Flavonols in Foods Protect the Mind – Healing Practice

Good nutrition protects brain health

food with antioxidant flavonols such as various fruits and vegetables protect cognitive ability. Good nutrition can help maintain brain health.

In a new study involving experts from Rush University Medical Center was the link between the inclusion of flavonols about diet and changes cognitive performance examined. The results are published in the journal “Neurology“published.

Dietary intake and cognitive abilities examined

The survey included 961 attendees at the middle age of 81 years old. None of the subjects had dementia at the start of the study. Annual questionnaires were used to record how often participants ate certain foods.

In addition, the researchers also asked participants about other factorssuch as level of education, time spent sedentary each day and participation in mentally stimulating activities.

In addition, tests have been carried out each year to Memory and the cognitive skills determine. The mean duration of follow-up during the study was seven years.

Classification according to flavonol intake

the average flavonol intake according to the study group researchers, was approximately ten milligrams a day. All participants were assigned to one of five groups based on the amount of flavonols they consumed.

Participants in the group with the lowest flavonol intake took approximately five milligrams per day, while the value in the group with the highest intake was average 15 milligrams lay eggs daily.

Determined cognitive performance

Based on the tests performed, the researchers calculated a Total Cognitive Ability Score and compared that to the consumption of flavonols.

Experts have found that participants with the highest intake of flavonols slower cognitive decline compared to the group with the lowest intake 0.4 units per decade exposed.

What role did the different flavonols play?

The study also four flavonols distinct:

  • kaempfer oil is found especially in kale, beans, tea, spinach and broccoli.
  • quercetin is found in tomatoes, kale, apples and tea.
  • myricetin is found in tea, wine, kale, oranges.
  • isorhamnetin is in pears, olive oil, wine and tomato sauce.

Kaempferol with the strongest effect

When evaluating individual flavonols, it was shown that participants consuming the most kaempfer oil a slower decline in cognitive values 0.4 units per decade compared to participants who had the lowest kaempferol intake.

The highest record of quercetin was with a 0.2 units slowest decline in cognitive scores per decade and highest consumption of myricetin with an around 0.3 units slower decline – each relative to lower uptake.

On the other hand, the researchers could not establish any link with cognition when taking isorhamnetin.

Diet can slow cognitive decline

Our study shows certain food choices can lead to slower cognitive decline“, says the author of the study Doctor Thomas M Holland in a Press release. The consumption of fruits, vegetables and tea seems like an easy way to improve brain health.

The effect is likely to be on the antioxidant and anti-inflammatory properties attributed to flavonols. However, Dr. Holland admitted that in the study there was a link between higher amounts of flavonols and an slower cognitive decline has been found, but this does not prove that flavonols are a direct cause. It is therefore now necessary to investigate the possible bases of the connection in further studies. (as)
