Daily supplementation of Matcha Green Tea Powder is found to enhance cognitive functions in elderly women.
The research performed a randomized, double-blind, placebo-controlled trial over a period of 12 weeks. The involvement of 61 participants who were community-dwelling elderly people was arranged, and these participants were randomly assigned to either a test group receiving a daily drink containing 3 grams of Matcha Green Tea Powder or a placebo group. Assessments of their cognitive function changes were made using a psychometric test battery. Also, the participants' daily food intake was monitored and recorded using a Brief-type Self-administered Diet History Questionnaire.
The results clearly indicated substantial enhancement in cognitive functions in women who were part of the active test group. It was observed in the Montreal Cognitive Assessment (MoCA) scoring scheme. An interesting pattern that came up in the dietary analysis was the significant inverse correlation between consumption of vitamin K in everyday food apart from test drinks and a change in MoCA. Overall, the study indicates that regular intake of Matcha Green Tea Powder can have protective effects against cognition decline, particularly in elderly women residing in the community.
