Does green tea protect the aging brain better than coffee? In this episode of Daily Value, we look at the evidence behind green tea's impact on brain aging, focusing on cerebral white matter lesions, Alzheimer’s risk, and brain atrophy. Drawing on studies like Shibata et al.'s recent publication in Science of Food (PMID: 39774601), we discuss how a certain threshold of green tea, but not coffee is associated with less white matter lesions in aged individuals.

Discussion Points:

• MRI findings on green tea’s association with reduced white matter lesion progression in older adults consuming a specific amount of cups daily.
• Past research observing a 5% reduction in hippocampal atrophy rate in green tea consumers (amounts discussed in episode).
• Brewing techniques and supplement tips to optimize EGCG content and/or minimize caffeine content of tea.
