Stress, Depression, and Anxiety

Matcha contains a unique amino acid called L-theanine, which may help reduce stress and anxiety. It's believed to increase the levels of the relaxing neurotransmitter GABA, soothing and relaxing the mind.

Cognitive Function and Mental Performance

The combination of caffeine and L-theanine in matcha can improve alertness and memory performance, boosting energy metabolism throughout the brain.

Heart Health and Cardiovascular System

Regular consumption of matcha may help reduce risk factors for heart disease, such as managing cholesterol levels and preventing damage to cellular membranes.

Weight Management and Metabolism

The plant compounds and caffeine in matcha may boost metabolic rate and speed up fat burning, especially in those with a high proportion of abdominal fat.

Gut Health and Digestion

Matcha is a good source of fiber, which can aid digestion and promote regular bowel movements.

Antioxidant and Anti-inflammatory Effects

Matcha is rich in antioxidants, particularly epigallocatechin gallate (EGCG), which neutralize harmful molecules and may have anti-inflammatory properties.

Skin Health and Aging

The antioxidants in matcha may also contribute to skin health, protecting against damage that can lead to aging.

Immune System Support

The vitamins and minerals in matcha, along with its antioxidants, can support a healthy immune system.

Exercise Performance and Recovery

Studies suggest that matcha could play a role in improving exercise performance and recovery by encouraging the body to break down fatty acids during exercise.

Japanese Study Summaries

1. Improvement of Sleep Quality and Social Cognitive Function by Continuous Intake of Matcha

This article discusses a clinical trial conducted by Ito En Ltd. and MCBI, a venture from Tsukuba University. The trial involved elderly individuals with Mild Cognitive Impairment (MCI) and Subjective Cognitive Decline (SCD) and aimed to evaluate the effects of continuous matcha intake on cognitive function. The results confirmed that continuous intake of matcha improved sleep quality and social cognitive function. These findings were presented at the Alzheimer's Association International Conference (AAIC) 2022 in San Diego, California, USA. The article also highlights that theanine, a component of matcha, has effects such as stress relief, sleep improvement, and improvement of working memory, while catechins have effects such as lowering blood cholesterol, reducing body fat, and improving working memory.

2. Matcha's Bactericidal Effect on Pneumococcus and Inhibition of Toxin - Effective Against Drug-Resistant Bacteria

This research paper from Niigata University explores the potent bactericidal properties of matcha on pneumococcus, including drug-resistant strains, and its ability to inhibit the harmful effects of PLY toxin. Conducted by the Microbial Infectious Diseases Department of Niigata University's Graduate School of Medical and Dental Sciences, the study found that matcha, even at drinking concentrations, can effectively kill pneumococcus and inhibit the effects of PLY toxin. The paper suggests that the consumption of matcha, which is increasingly being incorporated into various confectionery items, could potentially contribute to the achievement of the 'AMR Action Plan' proposed by the Japanese government. The research was funded by the 'Matcha and Health Research Association' and the findings were published in the international scientific journal Antibiotics.

3. Matcha: Quality and Health Benefits

This study explores the superior benefits of high-quality matcha, which contains more antioxidants and beneficial compounds compared to lower-quality variants. The quality of matcha significantly affects its nutritional profile, making high-quality matcha a healthier choice.

4. Uji Tea Village Publication

This article emphasizes the superior health benefits and unique taste profile of high-quality matcha, attributed to its higher theanine content. Theanine, discovered by Yajiro Sakado, is known for its calming effects and is more abundant in high-quality matcha. The document also highlights the importance of the tea bowl's size, thickness, and material in the overall matcha experience. It suggests that high-quality matcha, particularly those made from shaded tea like Gyokuro and Tencha, offers a richer taste and a more potent health boost. The potential of Tencha stems, rich in theanine, in food products is also discussed. This study reinforces the notion that choosing high-quality matcha is a worthwhile investment for both its superior taste and health benefits.

5. Elucidation of Part of the Mechanism by which Matcha Reduces Anxiety

This study from Kumamoto University provides significant insights into the calming effects of matcha, a type of powdered green tea. The research conducted by Assistant Professor Yuki Kurauchi and Professor Hiroshi Katsuki demonstrated that matcha and its extracts can reduce anxiety in mice. The study suggests that these calming effects might be due to the activation of dopamine D1 receptors and serotonin 5-HT1A receptors. The article also highlights the potential of matcha as a lifestyle choice that can promote health in daily life. The research findings were published in the Journal of Functional Foods.

6. Matcha and Health Study Group

This study emphasizes that matcha is rich in antioxidants, particularly catechins, which are known for their cancer-fighting properties. The research also mentions that matcha can help in weight loss by boosting metabolism and burning fat. It also points out that matcha can enhance mood and aid concentration due to the presence of an amino acid called L-Theanine. The research concludes by stating that matcha can also help prevent heart disease and lower bad cholesterol levels.

While the studies linked here provide a wealth of information, it's important to remember that everyone's body is different, and individual experiences with matcha may vary. As always, it's recommended to consult with a healthcare provider before making any significant changes to your diet or health regimen.
