What the researchers found was that runners given beer had a 3 fold reduction in the incidence of upper respiratory tract illnesses (URTI) after the marathon. They also had lower blood levels of interleukin-6 (IL-6) and high-sensitive c-reactive protein (hs-CRP); both are blood markers for inflammation in the body. This is a big deal for high intensity athletes. These athletes are known for URTI and inflammation due to the physiologic stress associated with prolonged exercise.
So how did beer help? Beer is a major source of phenolic compounds in the diet. Plant based phenolics possess anti-viral, anti-oxidant and anti-inflammatory properties. Remember beer is an extract of plant based materials (barley and hops). Other notable sources of plant based phenolic are green tea and the immune boosting botanical Echinacea. It is thought that products with multiple phenolic compounds work better that individual ones. More than 50 polyphenolic compounds have been identified in barley and hops.
