Some research shows that several of the components in matcha could help enhance brain function. One study in 23 people looked at how people performed on a series of tasks designed to measure brain performance. Some participants consumed either matcha tea or a bar containing 4 grams of matcha, while the control group consumed a placebo tea or bar. Those that consumed matcha showed improvements in attention, reaction time, and memory compared with those consuming the placebo. Another small study showed that consuming 2 grams of green tea powder daily for 2 months helped improve brain function in older people. Matcha has a higher concentration of caffeine than green tea. Depending on the type, brand, and processing, green tea tends to contain around 11–25 milligrams per gram (mg/g), while matcha contains 19–44 mg /g. Matcha also contains a compound called L-theanine, which alters the effects of caffeine, promoting alertness and helping avoid the crash in energy levels that can follow caffeine consumption. #matcha #foodmedicine
