Eleven healthy non-tea-drinking individuals were asked to drink five or six
cups of tea a day, while ten healthy non-tea and non-coffee-drinkers were
asked to drink the same amount of coffee, which has caffeine but not the
L-theanine that is in tea. The groups were randomly assigned. After two
weeks, blood samples were exposed to an antigen and production of interferon
gamma was measured.
