Green tea polyphenols for neuroprotection: effects against Alzheimer’s and Parkinson’s diseases

Green tea is a beverage consumed hot and cold worldwide for its taste and health benefits. In this chapter, we discuss the benefits of green tea consumption regarding neurodegenerative diseases, including Alzheimer’s and Parkinson’s diseases, two of the world’s most common neurodegenerative disorders. Green tea contains a range of beneficial phytochemicals that reduce inflammation and ease oxidative stress, which could be helpful in the prevention of neurodegeneration and prevent the onset of neurodegenerative diseases such as dementia and Parkinson’s. Epigallocatechin gallate is a commonly studied phytochemical from green tea, which has been shown to have numerous cytoprotective properties. In this chapter, we further discuss the mechanisms by which chemicals such as epigallocatechin gallate provide this neuroprotection.
