more on green tea

We’re HUGE green tea drinkers. From the way I talk about it, you’d think I work for one of the Japanese green tea companies. Alas, I do not. 🙂

Here is yet another study linking green tea with health benefits. In this case, brain healing properties.

• Titled, Green tea catechins potentiate the neuritogenic action of brain-derived neurotrophic factor: role of 67-kDa laminin receptor and hydrogen peroxide, the paper set out to explore green tea’s potential for increasing the activity of a nerve growth factor known as brain-derived neurotrophic factor (BDNF), essential for the growth, maintenance and survival of neurons.

Turns out that very low levels of this compound, EGCG, reach the brain when consuming green tea, and this was thought to be a barrier to using tea drinking as a natural delivery method to neural tissue. Until, of course, their experiments showed “for the first time that treatment with extremely low concentrations (<0.1 μ g/ml) of unfractionated green tea polyphenols (GTPP) and low concentrations (<0.5 μ M) of their active ingredient, epigallocatechin-3-gallate (EGCG), potentiated the neuritogenic ability of a low concentration (2 ng/ml) of BDNF."

Translation: It only takes low levels of EGCG to promote brain healing properties, so drink your green tea!
