Per up to date findings from a potential cohort research by the Nationwide Well being and Vitamin Examination Survey (NHANES) program, which collected knowledge from practically 12,000 adults representing the U.S. inhabitants, a better consumption of flavonols was related to:
- A 36 % lower in all-cause mortality
- A 55 % lower in cancer-specific mortality
- A 33 % lower in cardiovascular-specific mortality
Plus, when particular flavonols, a few of these measures (in addition to these for Alzheimer’s illness mortality danger) fared even higher.
“They’re distinctive primarily based on their chemical construction that helps to scavenge free radicals and cross the blood-brain barrier, resulting in neuroprotective and coronary heart well being advantages.”
—Michelle Routhenstein, MS, RD, CDCES, CDN, cardiovascular dietitian
Forward, see what specialists should say in regards to the hyperlink between flavonols and longevity—together with learn how to embody them into your eating regimen ASAP to reap its (fairly literal) life-giving advantages.

Flavonols are essentially the most ubiquitous of the bunch and are considered essentially the most energetic. “They’re distinctive primarily based on their chemical construction that helps to scavenge free radicals and cross the blood-brain barrier, resulting in neuroprotective and coronary heart well being advantages,” says Michelle Routhenstein, MS, RD, CDCES, CDN, cardiovascular dietitian at Solely Nourished.
To get much more area of interest, flavonols embody the likes of:
- Quercetin
- Kaempferol
- Myricetin
- Isorhamnetin
“These bioactives are non-essential vitamins that scientific analysis is more and more exhibiting could also be vital to residing and ageing nicely,” Routhenstein continues.
Well being advantages of consuming meals with flavonols
The advantages of flavonols are wide-ranging and are linked to perks that may shield your well being in some ways each now and over time. In accordance with Routhenstein, these bioactives assist to:
- Enhance blood movement
- Preserve wholesome blood stress and levels of cholesterol

“Flavonols might assist scale back plaque burden within the arteries, which is related to development of coronary heart illness,” Routhenstein provides.

However that’s to not say that different flavonols aren’t with out advantage. For example, in the latest findings from the NHANES research, myricetin (present in tea, berries, and nuts) was related to a whopping 66 % decline in Alzheimer’s illness mortality danger.
