See the bottom of this page for the ingredients highest in flavonoids.
What are flavonoids?
Flavonoids are phytochemicals (also known as polyphenols), these are the chemicals that plants use to defend themselves against disease. Research has shown that these same chemicals can prove equally beneficial to the human body.
Why does it matter to me?
Scientists are working on the proposition that dietary flavonoids are a key to protecting our health and preventing disease.
Tests have suggested that flavonoids co-ordinate the communication between our cells to benefit our system as a whole (cell signaling).Did you know?
- Flavonoids may help in preventing cancer by enabling the body to get rid of potentially harmful chemicals (carcinogens), and stopping mutations in our cells that can lead to cancer
- Flavonoids may enable cells to die off when they need to, avoiding the DNA damage that can lead to cancer
- Flavonoids may stop our body producing the new blood vessels that cancer uses to grow and survive (pathological angiogenesis)
- Flavonoids may decrease the risk of heart disease by reducing inflammation
Studies have shown (see link below) that a higher flavonoid intake provides protection against cognitive decline. Other studies have shown that flavonoids protect our skin from damaging UVR.
Research done on humans has consistently shown that diets high in fruits and vegetables which contain flavonoids lead to a considerable reduction in the risk of heart disease, stroke, high blood pressure, cancer, osteoporosis and cataracts.
Recent research has also shown a link between flavonoids and our gut health with flavonoids having a role in regulating gut microbes.
However whilst flavonoids have been present in the diets of people shown to have a reduced risk of these conditions, it presently cannot be determined whether this protection is directly attributable to flavonoids or the combination of flavonoids and other micronutrients.
There is a great deal of scientific interest in the protective effects of flavonoids but the conclusions of the research done to date are far from definite, however some human research has shown for example, that quercetin
(from onions & apples) significantly reduces the risk of lung cancer and myricetin
(from tea, red wine & parsley) reduces the risk of prostate cancer.How much should I have?
In the absence of an RDA we have a CYF starting guideline of 400mg plus per day for adults from as many different food
sources as possible. Members can adjust their target amounts.
Recent research has shown that high supplement doses of phytochemicals or polyphenols can be damaging to DNA, showing that the most beneficial dosage is from natural food sources - see link below.
