From the neuroprotective thread I decided to investigate the effect of black tea a little bit more. After some searches on the internet I found that black tea usage reduces risk for PD with 71 %. That's huge. I also read that grean tea does not reduce risk for PD. This fits perfectly with a recent study performed by MJFF in which EGCG was shown to not be neuroprotective; only mildly improving symptoms.
So I started to dig deeper on black tea. I found very interesting results. In a study from this summer it was shown that black tea stimulates autofagy. (http://rossscience.org/ojns/articles/2075-9088-2-1.pdf
) This autofagy process 'removes' alpha-synuclein. This process is orchestred by the teaflavins in black tea. However, what I do not know is whether the teaflavins can cross the Blood-Brain barrier. Anyone knows more about this ?
Are there also people that consume black tea for longer time span ? If so, did it help you in any way with your PD ?
