A new study found that higher long-term dietary intakes of flavonoids are associated with lower risks of Alzheimer’s disease and related dementias.
Researchers recently discovered that a low flavonoid intake was associated with Alzheimer’s risk, meaning a diet lacking berries, apples, tea, and other flavonoid rich foods could hold one of the keys to the disease.
The April 2020 study published in The American Journal of Clinical Nutrition found, “higher long-term dietary intakes of flavonoids are associated with lower risks of Alzheimer’s disease and related dementias (ADRD) in U.S. adults.” The study does not provide an immediate connection between the two but rather showcases an association.
According to Oregon State University, “Evidence suggesting that some flavonoids or flavonoid-rich foods may enhance cognitive function is currently limited, and it is not yet known whether their consumption could lower the risk of cognitive impairments and dementia in humans.” The University also stated that certain flavonoids have been shown to, “cross the blood-brain barrier and exert preventive effects towards cognitive impairments in animal models of normal and pathological aging.” Not only helpful for cardiovascular health, flavonoids are being investigated for their effect on the body all over the world.
A 2019 piece published in Nature Communications also found that foods rich in flavonoids could decrease the risk of cancer. Flavonoid rich foods include apples, berries, cocoa-based products, red grapes, and red wine and tea.
