The use of matcha in modern drinks has spread to North American cafés where, as in Japan, it has become integrated into lattes, iced drinks, milkshakes, and smoothies. A number of cafes have introduced lattes and iced drinks using matcha powder. It has also been incorporated into alcoholic beverages such as liqueurs. The health benefits of green tea and matcha have also raised significant interest in North America. Consequently, it can now be found in numerous health food products ranging from cereal to energy bars. In 2003, researchers from the University of Colorado found that the concentration of the antioxidant EGCG available from drinking matcha is up to 137 times greater than the amount of EGCG available from other commercially available green teas.
