Dietary patterns are widely recognised as contributors to cardiovascular and cerebrovascular disease.
Endothelial function, the elastic properties of large arteries and the
magnitude and timing of wave reflections are important determinants of
cardiovascular performance. According to the study by the University of Wollongong, posted in PubMed, several epidemiological studies suggest that the regular consumption of foods
and beverages rich in flavonoids is associated with a reduction in the
risk of several pathological conditions ranging from hypertension to
coronary heart disease, stroke and dementia.
The impairment of endothelial function is directly related to ageing
and an association between decreased cerebral perfusion and dementia
has been shown to exist. Cerebral blood flow (CBF) must be maintained
to ensure a constant delivery of oxygen and glucose as well as the
removal of waste products. Increasing blood flow is one potential way
for improving brain function and the prospect for increasing CBF with
dietary polyphenols is extremely promising. The major polyphenols shown
to have some of these effects in humans are primarily from cocoa, wine,
grape seed, berries, tea, tomatoes (polyphenolics and nonpolyphenolics),
soy and pomegranate.
