Matcha is full of good-for-you antioxidants, but unlike green tea, it’s not calorie-free. Why? Matcha is a powdered green tea that is prepared by whisking the powder with hot water, meaning you’re ingesting the tea leaves. On the plus side, the calories are very minimal and matcha boasts significantly more nutritional benefits than you would get with traditionally brewed leaf teas. In fact, 1/4-1/2 teaspoon of matcha is equal to eight to ten cups of regular tea in terms of its antioxidant power.
