Ashish Raj, New Delhi. A new study has found that people who eat a diet that contains at least half the flavonoid-rich foods such as strawberries, oranges, peppers and apples may have a 20 percent lower risk of cognitive impairment. Problems with Neurology, Medical Journal of the American Academy of Neurology. Studies have shown different types of flavonoids and have shown that flavonoids and anthocyanins may have the most protective effects.
Flavonoids are compounds found naturally in plants and are considered to be powerful antioxidants. It is thought that having too few antioxidants can contribute to cognitive decline as you age. “There is growing evidence that flavonoids are a powerhouse when your thinking is hampered by aging,” said Walter Willett, a researcher at DRPH, MD at Harvard University in Boston.
“Our results are exciting because they show that simple changes to your diet can help prevent cognitive decline,” Willett said.
At the beginning of the study, the average age of 49,493 women was 48 and the average age of 27,842 men was 51 years. Over more than 20 years of follow-up, people have completed a number of questions about how often they ate different foods. Different types of flavonoids calculate their intake by multiplying the flavonoid content of each food by its frequency.
Study participants twice assessed their own cognitive abilities during the study, asking, “Do you have more problems than usual with remembering recent events?” And “Do you have more problems than usual remembering a short list of items?” This assessment captures early memory problems when human memory has deteriorated enough to detect them, but not necessarily to detect them on screening tests.
The people in the group, representing a maximum of 20 percent of flavonoid consumers, had an average of about mill00 milligrams (mg) in their diet per day, compared to a minimum of 20 percent of flavonoid users, who had about 150. Mg per day in your diet. For example, strawberries contain about 180 milligrams of flavonoids per 100 grams, while apples contain about 113.
