EN Abstract:Some studies have ascribed a protective effect against neurodegenerative diseases to theβ-carbolines harman (H) and norharman (NH), which occur mostly in coffee and coffee substitutes.We determined the concentrations ofβ-carbolines and undesirable compounds (such as acrylamide)in roasted coffee substitute ingredients and found that chicory coffee was optimal. Twoin vivoexperiments were conducted with seventeen-month-old male Sprague Dawley rats fed a diet withthe addition of pure carboline standards in the first stage, and chicory in the second. We observed anincrease in the level of H and NH in blood plasma, as well as higher activity of animals in the batterybehavioral test, particularly in the second stage. The results ofin vitrostudies—particularly the levelof the expression in brain tissue of genes associated with aging processes and neurodegenerativediseases—clearly show the benefits of a diet rich inβ-carbolines.
