Researchers divided them into groups based on their daily intake of flavonols, ranging from five to 15 milligrams per day\u2014which is the amount in one cup of dark, leafy green vegetables.<\/span><\/p>\n<p><span>Participants underwent yearly tests of cognition and memory and were asked about the time they spent being physically and mentally active.<\/span><\/p>\n<p><span>Holland and his team then examined the effects of four major flavonols; kaempferol, quercetin, myricetin, and isorhamnetin, on the rate of cognitive decline over seven years.<\/span><\/p>\n<p><span>Among all flavonols, kaempferol showed the greatest benefit. Those consuming higher amounts of foods with kaempferol showed 0.4 units per decade reduced rate of cognitive decline compared to participants that ate the least.<\/span><\/p>\n<p><span>The next most effective flavonol was myricetin. Participants that ate myricetin-rich foods experienced 0.3 units per decade reduced rate of cognitive decline.\u00a0<\/span><\/p>\n<p><span>Of the other two flavonols, those who ate the most quercetin-rich foods had 0.2 units per decade slower rate of cognitive decline, while isorhamnetin showed no effect at all.<\/span><\/p>\n<h2>What Do Flavonols Do to Your Brain?<\/h2>\n<p><span>Holland said that various biochemical reactions, <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3249911\/\"><span>free radicals<\/span><\/a><span>, and reactive oxygen species can cause cellular, and eventually, organ-level damage.\u00a0<\/span><\/p>\n<p><span>\u201cWe call this damage to the cells in our bodies \u2018oxidative stress,\u2019\u201d he said.<\/span><\/p>\n<p><span>Previous <\/span><a href=\"https:\/\/www.frontiersin.org\/articles\/10.3389\/fnmol.2020.00041\/full#:~:text=Cellular%2C%20biochemical%20and%20molecular%20studies,mitochondrial%20DNA%2C%20and%20diminished%20repair.\"><span>studies <\/span><\/a><span>have found that oxidative stress is \u201cintricately\u201d linked to age-associated cognitive decline. They also found that increasing dietary antioxidant intake was able to reverse some of this decline.<\/span><\/p>\n<p><span>Holland explained that when we eat foods containing antioxidants like flavonols, they act as \u201creducing agents,\u201d that eliminate those free radicals and prevent further cellular damage.\u00a0<\/span><\/p>\n<p><span>\u201cThey help fight off inflammation and any harmful molecules that could be causing harm to your body,\u201d said <\/span><a href=\"https:\/\/www.linkedin.com\/in\/hoda-tantawi-5348a5172\/\"><span>Hoda Tantawi<\/span><\/a><span>, a registered dietitian at Staten Island University Hospital, part of Northwell Health in New York.<\/span><\/p>\n<h2>Whole Foods\u2014Better Flavonol Source Than Supplements<\/h2>\n<p><span>Tantawi emphasized that eating actual foods is always better than using flavonol supplements.\u00a0<\/span><\/p>\n<p><span>It makes these nutrients more bioavailable to the body. \u201cMeaning the body will absorb the nutrients in a more efficient way and allow us to reap the benefits of nutrients,\u201d she said.<\/span><\/p>\n<p><span>She added that another benefit of getting flavonols from food is that you\u2019re consuming all the nutrients the food contains, rather than only one nutrient from a supplement.\u00a0\u00a0<\/span><\/p>\n<p><span>Good sources of flavonols include berries, onions, red cabbage, kale, parsley, tea, red wine, dark chocolate, citrus foods, and soybeans.<\/span><\/p>\n<p><span>The <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6835347\/#:~:text=The%20richest%20plant%20sources%20of,kaempferol%2C%20respectively%20%5B17%5D.\"><span>richest sources<\/span><\/a><span> of kaempferol are green leafy vegetables like spinach and kale, and herbs that include dill and chives.\u00a0<\/span><\/p>\n<p><span>Cranberries, Swiss chard, and garlic are <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7395214\/\"><span>good sources<\/span><\/a><span> of myricetin.<\/span><\/p>\n<h2>An Observational Study<\/h2>\n<p><span>According to Holland, a limitation of this study is that it\u2019s observational, which raises the risk of residual confounding by measured and unmeasured factors.<\/span><\/p>\n<p><span>\u201cMeaning, there could be things the participants are doing that could help or harm their cognition that we are not measuring or privy to,\u201d he said.<\/span><\/p>\n<p><span>Another limitation is that diet was self-reported, which involved asking individuals to recall what they ate over the previous 12 months.
