Shayla Love, The Washington Post:
Matcha is green tea leaves crushed into a fine, electric green powder. Whisk the powder into warm or hot water, and it dissolves into a frothy drink.
In a regular cup of tea, tea leaves are just steeped in water, but when you drink matcha, you actually consume the whole leaf and the nutrients it contains. Drinking the whole leaf provides the antioxidants and health benefits, Sheth says, at higher levels than other superfoods such as like acai berries or goji berries.
At the same time, another component of the leaf, the secret behind the mellow matcha buzz, helps prevent the shaky coffee feeling: L-theanine.
“L-theanine is an amino acid, and studies have shown it provides a stress relief; it produces a calm feeling in our body,” [dietician Vandana Sheth] said. “But it doesn’t make us sleepy. When you combine that with the caffeine that’s in the matcha, you’re feeling more focused, you’re feeling alertness but without that jittery feeling when you consume a lot of caffeine from coffee.”
Now I’m curious to try matcha. I’ll see if I can find a local source.
