There is a growing body of evidence that dietary phytochemicals, in particular flavonoids, may exert beneficial effects on the central nervous system, by protecting neurons against stress-induced injury, suppressing nueroinflammation and by improving cognitive function (Spencer 2008).
Flavonoids are divided into six subgroups (1) Flavonols (e.g. kaempferol, quercetin), which are found in onions, leeks and broccoli, (2) flavones (e.g. apigenin, luteolin), which are found in parsley and celery, (3) isoflavones (e.g. diadzein, genistein), which are found in soy products, (4) Flavanones (e.g. hesperetin, naringenin), which are mainly found in citrus fruit and tomatoes, (5) flavanols (e.g. catechin, epicatechin, EGCG), which are abundant in green tea and rose hips, and (6) anthocyanidins (e.g. perlargonisin, cyanidin, malvidin) whose sources include berry frutis like blueberries, bilberries and blackberries (Manach 2004).
In the recent research by Shukitt-Hale et al., entitled Berry Fruit Enhances Beneficial Signaling in the Brain, which appeared in the Journal of Agriculture and Food Chemistry, 2012, 60(23) pp 5709-5715, the researchers found that the intake of berries and berry extracts had a direct effect on the brain. The extracts help prevent age-related neurodegeneration and resulting changes in cognitive and motor function. The berry fruits mediate signaling pathways involved in inflammation and cell survival in addition to enhancing neuroplasticity, neurotransmission and calcium buffering, all of which lead to attenuation of age- and pathology related deficitis in behavior. Their paper reviewed recent evidence for the beneficial signaling effects of berry fruits on the brain and behaviour.

The Last Quiz Answer:
The magnificent Bengal Tiger. So massive, who can resist its power. Yet, the Bengal Tiger is in danger of extinction. In the state of Madhya Pradesh, in Central India, Kanha National Park has become a sanctuary for these tigers. The Caspian, Bali, and Java tigers have all disappeared. In Kanha, the Wildlife Protection Society is trying to save the Bengals.
I absolutely love the Global Oneness Project. At BioImmersion we are all about the greening of our planet, systemic thinking, protecting ecosystems and the healing on all levels of our global community. The Global Oneness Project produces short films and documentaries that takes you into the heart of creating a healthy humanity worldwide. In this film the Path of Freedom you are taken into the harsh environment of a Rhode Island men’s prison where a group of fifty inmates are transforming their lives through the practice of meditation. It is only about 15 minutes. It is very beautiful!
