High
flavanol diet may lead to lower blood pressure - Science Daily, 10/21/20 -
"The findings, published in Scientific Reports, studied
the diet of more than 25,000 people in Norfolk, UK and compared what they ate
with their blood pressure. In contrast to most other studies investigating links
between nutrition and health, the researchers did not rely on study participants
reporting their diet, but instead measured flavanol intake objectively using
nutritional biomarkers -- indicators of dietary intake, metabolism or
nutritional status that are present in our blood ... The difference in blood
pressure between those with the lowest 10% of flavanol intake and those with the
highest 10% of intake was between 2 and 4 mmHg. This is comparable to meaningful
changes in blood pressure observed in those following a Mediterranean diet or
Dietary Approaches to Stop Hypertension (DASH) diet. Notably, the effect was
more pronounced in participants with hypertension." - See

The Foods That May Lower Dementia Risk - NYT, 5/20/20 -
"Compared with those in the 15th percentile or lower for
flavonoid intake, those in the 60th or higher had a 42 to 68 percent lower risk
for dementia, depending on the type of flavonoid consumed ... Intake of one type
of flavonoid, anthocyanins, abundant in blueberries, strawberries and red wine,
had the strongest association with lowered risk. Apples, pears, oranges, bananas
and tea also contributed ... the amount consumed by those who benefited the most
was not large. Their monthly average was about seven half-cup servings of
strawberries or blueberries, eight apples or pears, and 17 cups of tea"

Science Daily, 5/5/20 - "The research team determined
that low intake of three flavonoid types was linked to higher risk of dementia
when compared to the highest intake. Specifically: Low intake of flavonols
(apples, pears and tea) was associated with twice the risk of developing ADRD
... Low intake of anthocyanins (blueberries, strawberries, and red wine) was
associated with a four-fold risk of developing ADRD ... Low intake of flavonoid
polymers (apples, pears, and tea) was associated with twice the risk of
developing ADRD ... The results were similar for AD" - See

Flavonoid-rich diet protects against cancer and heart disease, study finds -
Science Daily, m8/13/19 - "Participants consuming about 500mg of total
flavonoids each day had the lowest risk of a cancer or heart disease-related
death ... It's important to consume a variety of different flavonoid compounds
found in different plant based food and drink. This is easily achievable through
the diet: one cup of tea, one apple, one orange, 100g of blueberries, and 100g
of broccoli would provide a wide range of flavonoid compounds and over 500mg of
total flavonoids."

Mulberry extract activates brown fat, shows promise as obesity treatment -
Science Daily, 10/26/16 - "a natural compound in
mulberries, called "rutin," can activate the BAT in our bodies to increase
metabolism and facilitate weight loss ... Rutin treatment significantly reduced
adiposity, increased energy expenditure, and improved glucose homeostasis in
both the genetically obese mice and the mice with diet-induced obesity.
Specifically, the researchers found that rutin directly binds to and stabilizes
SIRT1 (NAD-dependent deacetylase sirtuin-1), leading to hypoacetylation of PGC1α
protein, which stimulates Tfam transactivation and eventually augments
mitochondrial number and UCP1 activity in BAT" - See

Dietary
cocoa flavanols reverse age-related memory decline in mice - Science Daily,
10/26/14 - "Most methods of processing cocoa remove many
of the flavanols found in the raw plant ... 37 healthy volunteers, ages 50 to
69, were randomized to receive either a high-flavanol diet (900 mg of flavanols
a day) or a low-flavanol diet (10 mg of flavanols a day) for three months. Brain
imaging and memory tests were administered to each participant before and after
the study ... When we imaged our research subjects' brains, we found noticeable
improvements in the function of the dentate gyrus in those who consumed the
high-cocoa-flavanol drink ... The high-flavanol group also performed
significantly better on the memory test ... If a participant had the memory of a
typical 60-year-old at the beginning of the study, after three months that
person on average had the memory of a typical 30- or 40-year-old ... The precise
formulation used in the CUMC study has also been shown to improve cardiovascular

What Is Fisetin? And Does
It Slow Dementia? - Medscape, 4/3/14 - "The compound is known to have both
antioxidant and anti-inflammatory effects on brain cells. They have now
investigated the memory-protecting effects of fisetin in a strain of
double-transgenic Alzheimer's disease (AD) mice. Three-month-old mice had
fisetin added to their food. By 9 months of age, mice that had not received
fisetin began performing more poorly in water mazes, a standard test of animal
learning and memory. Mice fed fisetin daily performed as well as control mice
without the Alzheimer's transgene at both 9 months and 1 year old. The
researchers next found that in AD mice with memory impairment, pathways involved
in cellular inflammation were activated. In fisetin-fed AD mice, those pathways
were dampened, and anti-inflammatory molecules were activated" - See fisetin at Amazon.com

Ingredients in Chocolate, Tea, Berries Could Guard Against Diabetes - Science Daily, 1/20/14 -
"Researchers studied almost 2,000 healthy women
volunteers from TwinsUK who had completed a food questionnaire designed to
estimate total dietary flavonoid intake as well as intakes from six
flavonoid subclasses ... those who consumed plenty of anthocyanins and
flavones had lower insulin resistance. High insulin resistance is associated
with Type 2 diabetes, so what we are seeing is that people who eat foods
rich in these two compounds -- such as berries, herbs, red grapes, wine- are
less likely to develop the disease ... We also found that those who ate the
most anthocyanins were least likely to suffer chronic inflammation -- which
is associated with many of today's most pressing health concerns including
diabetes, obesity, cardiovascular disease, and cancer ... those who consumed
the most flavone compounds had improved levels of a protein (adiponectin)
which helps regulate a number of metabolic processes including glucose
levels" - See

Celery, artichokes contain flavonoids that kill human pancreatic cancer
cells - Science Daily, 8/15/13 - "Apigenin alone
induced cell death in two aggressive human pancreatic cancer cell lines. But
we received the best results when we pre-treated cancer cells with apigenin
for 24 hours, then applied the chemotherapeutic drug gemcitabine for 36
hours ... our study indicated that taking antioxidant supplements on the
same day as chemotherapeutic drugs may negate the effect of those drugs ...
One of the ways that chemotherapeutic drugs kill cells is based on their
pro-oxidant activity, meaning that flavonoids and chemotherapeutic drugs may
compete with each other when they're introduced at the same time ... In one
of the cancer cell lines, the percentage of cells undergoing apoptosis went
from 8.4 percent in cells that had not been treated with the flavonoid to
43.8 percent in cells that had been treated with a 50-micromolar dose. In
this case, no chemotherapy drug had been added"

prostate cancer compared with those men with the lowest flavonoid intake ...
higher total flavonoid intake was associated with reduced odds for
aggressive prostate cancer in both African-American and European-American
men, but no individual subclass of flavonoids appeared to be protective
independently, suggesting that it is important to consume a variety of
plant-based foods in the diet, rather than to focus on one specific type of
flavonoid or flavonoid-rich food"

Dark
chocolate, cocoa compounds, may reduce blood pressure - Science Daily,
8/14/12 - "The researchers reviewed evidence from
short-term trials in which participants were given dark chocolate or cocoa
powder daily and found that their blood pressure dropped slightly compared
to a control group ... Cocoa contains compounds called flavanols, thought to
be responsible for the formation of nitric oxide in the body. Nitric oxide
causes blood vessel walls to relax and open wider, thereby reducing blood
pressure. The link between cocoa and blood pressure stems from the discovery
that the indigenous people of San Blas Island in Central American, who drink
flavanol-rich cocoa drinks every day, have normal blood pressure regardless
of age ... Flavanol-rich chocolate or cocoa powder reduced blood pressure on
average by 2-3 mm Hg" - [Abstract]

Flavonoid compound found in foods and supplements may prevent the formation
of blood clots, study suggests - Science Daily, 5/8/12 -
"It's not always fully appreciated that the majority
of Americans will die as the result of a blood clot in either their heart or
their brain ... The study focused on protein disulfide isomerase (PDI) which
is found in all cells. Investigators in BIDMC's Division of Hemostasis and
Thrombosis had previously shown that PDI is rapidly secreted from both
platelets and endothelial cells during thrombosis, when a clot forms in a
blood vessel, and that inhibition of PDI could block thrombosis in a mouse
model ... Among the more than 5,000 compounds that were screened,
quercetin-3-rutinoside (rutin) emerged as the most potent agent ...
Surprisingly, studies of the rutin molecule demonstrated that the same part
of the molecule that provides rutin with its ability to inhibit PDI also
prevents the compound from entering cells ... "That finding explained how
this compound can be both a potent inhibitor of PDI and a safe food
supplement," ... Rutin proved to be the most potently anti-thrombotic
compound that we ever tested in this model ... This discovery suggests that
a single agent can treat and prevent both types of clots" - See

Eating flavonoids protects men against Parkinson's disease, study finds
- Science Daily, 4/4/12 - "This latest study is the
first study in humans to show that flavonoids can protect neurons against
diseases of the brain such as Parkinson's ... male participants who ate the
most flavonoids were shown to be 40 per cent less likely to develop the
disease than those who ate the least. No similar link was found for total
flavonoid intake in women ... a sub-class of flavonoids called anthocyanins
may have neuroprotective effects ... In this study the main protective
effect was from higher intake of anthocyanins, which are present in berries
and other fruits and vegetables including aubergines, blackcurrants and
blackberries. Those who consumed the most anthocyanins had a 24 per cent
reduction in risk of developing Parkinson's disease and strawberries and
blueberries were the top two sources in the US diet" - See

Skip the carrots. Chocolate improves eyesight, too - MSNBC, 8/8/11 -
"They took the tests twice, once after eating a dark
chocolate bar, and once after eating a white chocolate bar. The difference
between the two chocolate bars was the amount of flavanols -- a natural
compound in cocoa -- they contained. Of course, the dark chocolate bar
contained loads of cocoa flavanols, the white chocolate bar only a trace ...
the study participants did perform better on the vision tests and on some of
the brain function tests after eating the dark chocolate ... They attribute
their findings to cocoa flavanol’s known ability to increase blood flow to
the brain, and they speculate that the stuff might also increase blood flow
to the retina of the eye"

Eating berries may lower risk of Parkinson's - Science Daily - Science
Daily, 2/13/11 - "Flavonoids are found in plants and
fruits and are also known collectively as vitamin P and citrin. They can
also be found in berry fruits, chocolate, and citrus fruits such as
grapefruit ... participants were followed for 20 to 22 years ... the top 20
percent who consumed the most flavonoids were about 40 percent less likely
to develop Parkinson's disease than the bottom 20 percent of male
participants who consumed the least amount of flavonoids. In women, there
was no relationship between overall flavonoid consumption and developing
Parkinson's disease. However, when sub-classes of flavonoids were examined,
regular consumption of anthocyanins, which are mainly obtained from berries,
were found to be associated with a lower risk of Parkinson's disease in both
men and women" - See

Chocolate eaters
may have healthier hearts: study - MSNBC, 11/8/10 -
"The authors found that women older than 70 who ate
chocolate at least once per week were 35 percent less likely to be
hospitalized or die from heart disease over the course of the study, and
nearly 60 percent less likely to be hospitalized or die from heart failure
... The danger is that many people will start eating more of it than is
necessary, without cutting back in calories from other snacks, which will
result in weight gain and will counteract any beneficial effects of
chocolate ... Flavonoids are thought to reduce the risk of heart disease,
the leading cause of death in many industrialized countries, by helping to
increase nitric oxide, which in turn helps boost the functioning of blood
vessels and lower blood pressure"

found a protective effect from a cocoa drink with 375 mg of flavanols, but
according to researchers, a standard or recommended dosage has not yet been
defined to achieve optimal health benefit ... In the current study, the
benefit seen from the two-fold increase in circulating angiogenic cells was
similar to that achieved by therapy with statins and with lifestyle changes
such as exercise and smoking cessation"

Dark
chocolate lowers blood pressure, research finds - Science Daily, 6/28/10
-
"Flavanols have been shown to increase the formation
of endothelial nitric oxide, which promotes vasodilation and consequently
may lower blood pressure. There have, however, been conflicting results as
to the real-life effects of eating chocolate. We've found that consumption
can significantly, albeit modestly, reduce blood pressure for people with
high blood pressure but not for people with normal blood pressure ... The
pressure reduction seen in the combined results for people with
hypertension, 5mm Hg systolic, may be clinically relevant -- it is
comparable to the known effects of 30 daily minutes of physical activity
(4-9mm Hg) and could theoretically reduce the risk of a cardiovascular event
by about 20% over five years"

Chemicals Found In Fruit And Vegetables Offer Dementia Hope - Science
Daily, 7/19/09 - "a new concept is emerging that
suggests flavonoids do not act simply as antioxidants but exert their
biological effects through other mechanisms. A small number of recent

administration of green tea flavonoids or grape flavonoids reduces brain
pathology and, in some cases, improves cognition. Dr Williams and colleagues
have focused their own cellular studies on a flavonoid called epicatechin,
which is abundant in a number of foodstuffs, including cocoa ... epicatechin
protects brain cells from damage but through a mechanism unrelated to its
antioxidant activity and shown in laboratory tests that it can also reduce
some aspects of Alzheimer’s disease pathology" - See

Plant Flavonoid In Celery And Green Peppers Found To Reduce Inflammatory
Response In The Brain - Science Daily, 5/20/08 -
"The new study looked at luteolin (LOO-tee-OH-lin), a plant flavonoid known
to impede the inflammatory response in several types of cells outside the
central nervous system ... Those cells that were also exposed to luteolin
showed a significantly diminished inflammatory response. Jang showed that
luteolin was shutting down production of a key cytokine in the inflammatory
pathway, interleukin-6 (IL-6). The effects of luteolin exposure were
dramatic, resulting in as much as a 90 percent drop in IL-6 production in
the LPS-treated cells ... Inflammatory cytokines such as interleukin-6 are
very well known to inhibit certain types of learning and memory that are
under the control of the hippocampus, and the hippocampus is also very
vulnerable to the insults of aging ... If you had the potential to decrease
the production of inflammatory cytokines in the brain you could potentially
limit the cognitive deficits that result" - See

pro-inflammatory signaling proteins and DNA reorganization/expression. These
effects were not observed when cells were treated with either compounds alone.
The antioxidant effects of ascorbic acid and rutin also prevented protein
modifications by lipid peroxidation products. Further, ascorbic acid stimulated
rutin-protein adduct formation, which supports intra/extracellular signaling and
the Nrf2/ARE antioxidant pathway, contributing to the protective effects against
UV-induced oxidative stress. The combined effect of ascorbic acid and rutin

The 5,7-Dimethoxyflavone
Suppresses Sarcopenia by Regulating Protein Turnover and Mitochondria
Biogenesis-Related Pathways - Nutrients. 2020 Apr 13 -
"Sarcopenia is a muscle disease featured by the loss of
muscle mass and dysfunction with advancing age. The 5,7-dimethoxyflavone (DMF),
a major flavone found in Kaempferia parviflora, has biological activities,
including anti-diabetes, anti-obesity, and anti-inflammation ...
Eighteen-month-old mice were orally administered DMF at the dose of 25
mg·kg-1·day-1 or 50 mg·kg-1·day-1 for 8 weeks. DMF not only stimulated grip
strength and exercise endurance but also increased muscle mass and volume.
Besides, DMF stimulated the phosphatidylinositol 3-kinase-Akt pathway,
consequently activating the mammalian target of rapamycin-eukaryotic initiation
factor 4E-binding protein 1-70-kDa ribosomal protein S6 kinase pathway for
protein synthesis. DMF reduced the mRNA expression of E3 ubiquitin ligase- and
autophagy-lysosomal-related genes involved in proteolysis via the
phosphorylation of Forkhead box O3. DMF upregulated peroxisome proliferator-activated
receptor-gamma coactivator 1 alpha, nuclear respiratory factor 1, and
mitochondrial transcription factor A along with the increase of relative
mitochondrial DNA content. DMF alleviated inflammatory responses by reducing the
tumor necrosis factor-alpha and interleukin-6 serum and mRNA levels.
Collectively, DMF can be used as a natural agent to inhibit sarcopenia via
improving protein turnover and mitochondria function" - See

Jan 29 - "Oxidative stress plays an important role in
the pathogenesis of Parkinson's disease (PD), particularly the inhibition of
mitochondrial complex-I. This study aimed to evaluate the effect of fisetin in
the rotenone-induced rat model of PD. Rotenone was administered (2 mg/kg s.c.)
for 35 days to induce PD in animals. Fisetin was administered at two doses
(10 mg/kg and 20 mg/kg p.o.) for 25 days to the animals that were given rotenone
... Fisetin treatment improved motor function in the cylinder test and reversed
the rotenone-induced changes in mitochondrial enzymes, striatal dopamine levels,
antioxidant enzyme levels and histological changes. An important finding of this
study was both the doses of fisetin significantly (p < 0.05) enhanced

Flavanol-rich lychee
fruit extract substantially reduces progressive cognitive and molecular deficits
in a triple-transgenic animal model of Alzheimer disease - Nutr Neurosci.
2019 Oct 11:1-15 - "Effective treatment to prevent or
arrest the advance of Alzheimer disease (AD) has yet to be discovered. We
investigated whether OligonolR, an FDA-approved flavanol-rich extract prepared
from lychee fruit and green tea, exerted beneficial effects relevant to AD in a
triple transgenic male mouse model of AD (3×Tg-AD). At 9 months of age,
untreated 3×Tg-AD mice vs. wild-type (WT) controls displayed cognitive deficits
in behavioral assays and, at 12 months, elevated levels of hippocampal amyloid
beta-protein (Aβ), amyloid precursor protein (APP), tau phosphorylation, and
pro-inflammatory cytokines. 3×Tg-AD mice given Oligonol showed fewer cognitive
deficits and attenuated pathological indices at 12 months. Oligonol treatment of
3×Tg-AD mice modulated expression of some critical brain proteins that involve
multiple pathways relevant to mitochondrial dysfunction, proteasomal failure,
endoplasmic reticulum (ER) stress and synaptic impairment. Together, these
results demonstrate that continuous Oligonol treatment attenuates AD-like
pathology and cognitive impairment of 3×Tg-AD mice and set the stage for

Inhibition
of advanced glycation end-product formation on eye lens protein by rutin -
Br J Nutr. 2011 Aug 25:1-9 - "Formation of advanced
glycation end products (AGE) plays a key role in the several pathophysiologies
associated with ageing and diabetes, such as arthritis, atherosclerosis, chronic
renal insufficiency, Alzheimer's disease, nephropathy, neuropathy and cataract.
This raises the possibility of inhibition of AGE formation as one of the
approaches to prevent or arrest the progression of diabetic complications.
Previously, we have reported that some common dietary sources such as fruits,
vegetables, herbs and spices have the potential to inhibit AGE formation.
Flavonoids are abundantly found in fruits, vegetables, herbs and spices, and
rutin is one of the commonly found dietary flavonols. In the present study, we
have demonstrated the antiglycating potential and mechanism of action of rutin
using goat eye lens proteins as model proteins. Under in vitro conditions, rutin
inhibited glycation as assessed by SDS-PAGE, AGE-fluorescence, boronate affinity
chromatography and immunodetection of specific AGE. Further, we provided insight
into the mechanism of inhibition of protein glycation that rutin not only
scavenges free-radicals directly but also chelates the metal ions by forming
complexes with them and thereby partly inhibiting post-Amadori formation. These
findings indicate the potential of rutin to prevent and/or inhibit protein
glycation and the prospects for controlling AGE-mediated diabetic pathological
conditions in vivo" - See

Naringin
Protects against Kainic Acid-Induced Status Epilepticus in Rats: Evidence for an
Antioxidant, Anti-inflammatory and Neuroprotective Intervention - Biol Pharm
Bull. 2011;34(3):360-5 - "The effect of naringin, a
bioflavanoid, with potent antioxidant activity was studied on kainic acid
(KA)-induced seizures, cognitive deficit and oxidative stress. Rats were
administered KA (10 mg/kg intraperitoneally (i.p.)) and observed for behavioral
changes and incidence and latency of convulsions over 4 h. The rats were
thereafter sacrificed and oxidative stress parameters like malondialdehyde (MDA)
and glutathione (GSH) were estimated in the brain. The level of proinflammatory
cytokine, tumor necrosis factor (TNF)-α was also determined in the rat brain. It
was observed that pretreatment with naringin (20, 40, 80 mg/kg, i.p.)
significantly (p<0.001) increased the latency of seizures as compared to the
vehicle treated-KA group. Naringin (40, 80 mg/kg) also significantly prevented
the increase in MDA and fall in GSH levels due to KA. In addition, naringin
dose-dependently attenuated the KA-induced increase in the TNF-α levels of
brain. The pretreatment with naringin also significantly increased retention
latency in the passive avoidance task. This shows that naringin reduced the
cognitive deficit induced by KA. The results of our study suggest that naringin
has therapeutic potential since it suppresses KA-induced seizures, cognitive
impairment and oxidative stress in the brain. These neuroprotective effects are
a result of its antioxidant and anti-inflammatory activity" - See

Flavanol-rich cocoa ameliorates lipemia-induced endothelial dysfunction -
Heart Vessels. 2010 Dec 8 - "Consumption of flavanols
improves chronic endothelial dysfunction. We investigated whether it can also
improve acute lipemia-induced endothelial dysfunction. In this randomized,
placebo-controlled, double-blind, crossover trial, 18 healthy subjects received
a fatty meal with cocoa either rich in flavanols (918 mg) or flavanol-poor.
Flow-mediated dilation (FMD), triglycerides, and free fatty acids were then
determined over 6 h. After the flavanol-poor fat loading, the FMD deteriorated
over 4 h. The consumption of flavanol-rich cocoa, in contrast, improved this
deterioration in hours 2, 3, and 4 without abolishing it completely. Flavanols
did not have any influence on triglycerides or on free fatty acids.
Flavanol-rich cocoa can alleviate the lipemia-induced endothelial dysfunction,
probably through an improvement in endothelial NO synthase"

Flavonoids,
proanthocyanidins, and cancer risk: a network of case-control studies from Italy
- Nutr Cancer. 2010 Oct;62(7):871-7 - "Total flavonoids,
flavanones, and flavonols were inversely related to oral and laryngeal cancers
(ORs, respectively 0.56 and 0.60 for total flavonoids; 0.51 and 0.60 for
flavanones; and 0.62 and 0.32 for flavonols). Flavanols were also inversely
related to laryngeal cancer (OR = 0.64), whereas flavanones were inversely
related to esophageal cancer (OR = 0.38). A reduced risk of colorectal cancer
was found for high intake of anthocyanidins (OR = 0.67), flavonols (OR = 0.64),
flavones (OR = 0.78), and isoflavones (OR = 0.76). Inverse relations with breast
cancer were found for flavones (OR = 0.81) and flavonols (OR = 0.80). Flavonols
(OR = 0.63) and isoflavones (OR = 0.51) were inversely associated to ovarian
cancer, whereas flavonols (OR = 0.69) and flavones (OR = 0.68) were inversely
associated to renal cancer. No association between flavonoids and prostate
cancer emerged. We found inverse associations between proanthocyanidins and
colorectal cancer. These associations appeared stronger for proanthocyanidins
with a higher degree of polymerization (OR = 0.69 for ≥ 10 mers)"

Flavonoids, proanthocyanidins, and the risk of stomach cancer - Cancer
Causes Control. 2010 Jun 3 - "Strong inverse
relations were found for proanthocyanidins. The OR was 0.44 (95% CI,
0.25-0.76) for monomers and dimers combined and 0.36 (95% CI, 0.21-0.63) for
polymers with three or more mers. Further adjustment for fruit and
vegetables, or vitamin C, did not materially change these associations. This
is the first epidemiological study to suggest that dietary proanthocyanidins
have a favorable role on gastric cancer risk"

Impact
of cocoa flavanol consumption on blood pressure responsiveness to exercise
- Br J Nutr. 2010 Jan 19:1-5 - "randomised to
consume single servings of either a high-flavanol (HF, 701 mg) or a
low-flavanol (LF, 22 mg) cocoa beverage in a double-blind, cross-over design
... the BP response to exercise (area under BP curve) was attenuated by HF
compared with LF. BP increases were 68 % lower for DBP (P = 0.03) and 14 %
lower for mean BP (P = 0.05). FMD measurements were higher after taking HF
than after taking LF (6.1 (se 0.6) % v. 3.4 (se 0.5) %, P < 0.001). By
facilitating vasodilation and attenuating exercise-induced increases in BP,
cocoa flavanols may decrease cardiovascular risk and enhance the
cardiovascular benefits of moderate intensity exercise in at-risk
individuals"

Flavonoid intake and disability-adjusted life years due to Alzheimer's and
related dementias: a population-based study involving twenty-three developed
countries - Public Health Nutr. 2010 Jan 11:1-7 -
"Flavonols and combined flavonoids (all five
combined) intakes were the only two parameters with significant (P < 0.05)
negative dementia correlations. Multiple linear regression models confirmed
this relationship, and excluded confounding from some other dietary and
non-dietary factors. Similar analyses with non-dementia,
neurological/psychiatric diseases did not yield significant correlations.
CONCLUSIONS: At a global level, and in the context of different genetic
backgrounds, our results suggest that higher consumption of dietary
flavonoids, especially flavonols, is associated with lower population rates
of dementia in these countries"

Luteolin reduces IL-6 production in microglia by inhibiting JNK
phosphorylation and activation of AP-1 - Proc Natl Acad Sci U S A. 2008
May 19 - "Luteolin consumption reduced LPS-induced
IL-6 in plasma 4 h after injection. Furthermore, luteolin decreased the
induction of IL-6 mRNA by LPS in hippocampus but not in the cortex or
cerebellum. Taken together, these data suggest luteolin inhibits LPS-induced
IL-6 production in the brain by inhibiting the JNK signaling pathway and
activation of AP-1 in microglia. Thus, luteolin may be useful for mitigating
neuroinflammation"

Dietary flavonoid intake and risk of cancer in postmenopausal women: The
Iowa Women's Health Study - Int J Cancer. 2008 May 19 -
"After multivariable adjustment, lung cancer
incidence was inversely associated with intakes of flavanones (HR = 0.68;
95% CI: 0.53-0.86, all results highest vs. lowest quintile) and
proanthocyanidins (HR = 0.75; 95% CI: 0.57-0.97). Among current and past
smokers, those with intakes in the highest quintile for flavanones (HR =
0.66; 95% CI: 0.50-0.86), and proanthocyanidins (HR = 0.66; 95% CI;
0.49-0.89) had significantly lower lung cancer incidence than those in the
lowest quintile. Similar associations were not seen in never smokers.
Isoflavone intake was inversely associated with overall cancer incidence (HR
= 0.93, 95% CI: 0.86-1.00). This study provides further support for a
beneficial effect of flavonoid intake on lung cancer risk, especially among
current and past smokers"

Flavonoids and ovarian cancer risk: A case-control study in Italy - Int
J Cancer. 2008 May 19 - "In logistic regression
models including study center, education, year of interview, parity, oral
contraceptive use and family history of ovarian or breast cancer or both, an
inverse relation with significant trend in risk was found between ovarian
cancer and flavonols [odds ratio (OR), 0.63; 95% confidence intervals (CI)
0.47-0.84] as well as isoflavones (OR, 0.51; 95% CI, 0.37-0.69), comparing
the highest versus the lowest quintile. Further adjustment for fruit and
vegetable intake did not modify these associations, suggesting that
isoflavones and flavonols may have a distinct role in explaining the effect
of fruit and vegetable against ovarian cancer. On the basis of our findings
and the relevant literature, we infer that isoflavones, and perhaps
flavonols, may have favorable effects with respect to ovarian cancer risk"
