AI Article Synopsis
- Matcha Green Tea Powder is rich in health-promoting compounds like tea catechins, lutein, and vitamin K, which may enhance cognitive function in elderly individuals.
- A 12-week randomized, double-blind trial involved 61 participants who either consumed Matcha or a placebo daily, with cognitive function measured using psychometric tests.
- The study found a significant improvement in cognitive scores for women taking Matcha, suggesting it may help protect against cognitive decline in elderly women.
Article Abstract
Matcha Green Tea Powder contains a variety of active ingredients beneficial to health, such as tea catechins, lutein and vitamin K. It is also known that these ingredients confer benefits upon cognitive functions of elderly people. Therefore, we aimed to investigate the relationship between a daily supplementation of Matcha and the change in cognitive functions of community-dwelling elderly people. A randomized, double-blind, placebo-controlled 12-week trial was performed. Sixty-one participants were recruited and randomly assigned to receive test drink containing 3g powder from fresh Matcha or placebo powder per day. Changes in cognitive function were assessed utilizing a psychometric test battery. Daily food intake was assessed by a Brief-type Self-administered Diet History Questionnaire (BDHQ). In the gender-specific analysis, a significant cognitive enhancement was observed in the Montreal Cognitive Assessment (MoCA) score in the active group of women. In dietary analysis, we found a significant inverse correlation between consumption of vitamin K in daily diet, excluding test drinks, and change in MoCA. The present study suggests that daily supplementation of Matcha Green Tea Powder has protective effects against cognitive decline in community-dwelling elderly women.

Unlabelled: Studies have suggested that phytochemicals in green tea have systemic anti-inflammatory and neuroprotective effects. However, the mechanisms behind these effects are poorly understood, possibly due to the differential metabolism of phytochemicals resulting from variations in gut microbiome composition. To unravel this complex relationship, our team utilized a novel combined microbiome analysis and metabolomics approach applied to low complexity microbiome (LCM) and human colonized (HU) gnotobiotic mice treated with an acute dose of powdered matcha green tea.

Background/objectives: This study tested the influence of in vitro digestion on the release of organic acids and low molecular weight saccharides of matcha.
Methods: The concentrations of analytes in the raw and undigested portion of matcha were measured using HPLC with spectrometric and refractometric detection to establish their residual values after a two-step enzymatic digestion that was finally presented as a retention factor.
Results: It was established that dry matter digestibility values after simulated gastric and both gastric and intestinal phases were 67.

Article Synopsis
- Tea leaf spot, caused by the fungus Didymella segeticola, significantly reduces tea yield and quality in high-mountain plantations of Southwest China due to a lack of understanding and control measures.
- The infection process involves the germination of conidia on leaf surfaces, leading to necrotic lesions and damage to chloroplasts, which affects the leaf's structural integrity.
- Through transcriptomic and metabolomic analyses, researchers identified two crucial genes (DsHAD and DsADH) that influence the fungus's virulence and its response to oxidative stress, providing insights for developing management strategies.
