Dietary flavonoids are neuroprotective through Nrf2-coordinated induction of endogenous cytoprotective proteins

These data have perpetuated the belief that the protective effects of flavonoids result from direct anti–oxidant actions at the levels of the cerebral vasculature and brain parenchyma.
... flavonoids may promote neural protection by facilitating the expression of gene products responsible for detoxifying the ischemic microenvironment through both anti–oxidative and anti–inflammatory actions.
In particular, the transcriptional factor nuclear factor erythroid 2–related factor 2 has emerged as a critical regulator of flavonoid–mediated protection through the induction of various cytoprotective genes...

An article in Medical News Today, 9th April, states:

"Men who regularly consume foods rich in flavonoids, such as berries, apples, certain vegetables, tea and red wine, may significantly reduce their risk for developing Parkinson's disease, according to a study published in the journal Neurology this week that saw no such effect among women.

Flavonoids are naturally occurring, bioactive compounds present in many plant-based foods and drinks.

In this study, the main protective effect appeared to come from a subclass of flavonoids known as anthocyanins, which are present in berries such as blackcurrants and blackberries, and other fruits, and also certain vegetables, such as aubergines.

The research was led by Dr Xiang Gao,"
