Green tea is a beverage that has been consumed for centuries. It is one of the most popular beverages in the world. Green tea is a great way to stay healthy and maintain a healthy lifestyle. The benefits of green tea may include weight loss, heart disease prevention, and improved brain function.
Green tea leaves are from Camellia Sinensis, an evergreen shrub native to Asia. It is made by placing the leaves in hot water and allowing them to steep for a few minutes. Drinking green tea may have many health benefits, including improved cognitive function, reduced blood pressure, and weight loss.
Green tea contains epigallocatechin gallate. EGCG is an antioxidant that helps reduce oxidative stress and protect cells from damage. And it could help improve brain function.
By relaxing blood vessels and reducing the production of hormones that cause blood vessels to constrict, EGCG reduces blood pressure. Effectively assisting to create a healthier cardiovascular lifestyle.
Ll-theanine, an amino acid that produces alpha waves in the brain, is also present in Green tea. Alpha waves are associated with relaxation and reduced stress levels.
Drinking green tea appears to help reduce stress levels, improve moods, and promote overall relaxation. The numerous benefits of green tea are worth reading about in more detail. Check out takeaways from these great studies.
L-Theanine Consumption to Manage Stress and Anxiety Levels
Stress is a normal response to an abnormal situation. In a stressful situation, the body prepares itself for action by increasing heart rate, blood pressure, breathing rate and releasing hormones like adrenaline and cortisol.
200-400 mg/day of L-theanine may reduce stress and anxiety in people exposed to stressful conditions.
Possible benefits of Green Tea for cognition and mood
Ffor thousands of years we have been drinking green tea. As it is experiencing a surge in popularity in Western culture and millions of people all over the world drink green tea every day, it is relevant to understand its effects on the human brain. In this study, numerous claims about the benefits of green tea consumption are stated and investigated through a peer review and assessment of 21 other studies.
Researchers presented evidence that green tea influences psychopathological symptoms (e.g. reduction of anxiety), cognition (e.g. benefits in memory and attention) and brain function (e.g. activation of working memory seen in functional MRI).
No single ingredient of green tea is responsible for its beneficial effects. The finding that cognitive benefits exist with the combined influence of both caffeine and l-theanine, and separate administration of either substanc offers a lesser impact exemplifies this finding.
Green tea extract supplementation on obesity
Green tea may be useful for weight loss. The best results seem to be with doses <500 mg/day and treatment durations <12 weeks.
Effects of green tea on energy expenditure
Green tea has caffeine and catechins. Caffeine increases energy expenditure by increasing sympathetic nervous system activity. Tea catechins increase energy expenditure by increasing fat oxidation.
Safety of green tea beverages and dried green tea extracts as nutritional supplements
Green tea catechins are tolerable for human consumption at doses of up to 300mg/day. This is based on studies of green tea consumption in humans, animal studies, and clinical trials.
