The book "Role of Beer and Three of Its Components on Degenerative Processes" offers a comprehensive examination of the potential health-promoting properties of beer, particularly freeze-dried blonde lager and its bioactive components: xanthohumol, choline, and folic acid. It is presented that moderate beer consumption can be associated with the prevention of chronic diseases, including cancer. The study employs various in vivo and in vitro tests to analyze the toxicological and antitoxicological properties of these components. The results suggest that freeze-dried blonde lager has significant nutraceutical value, especially concerning the promotion of longevity and the protection of DNA from free radicals. The research highlights the role of xanthohumol, which mimics the biological activities of beer and is thus considered promising for its chemopreventive effects.
