How does the seemingly unremarkable yeast powder exert this magical effect? In an interview with Esquire magazine, Mr. Koch explained the mystery in detail from a professional perspective. He said that alcohol dehydrogenase contained in dry yeast powder, as a bioactive enzyme, can play a role similar to that of human liver. Before alcohol reaches the brain and acts on the nervous system, alcohol macromolecules are converted into carbon, hydrogen and oxygen, which keeps drinkers awake and unaffected by alcohol. He also suggested that dry yeast powder can be mixed into yogurt, which tastes good and has the effect of staying awake when drinking. Why not?
However, Mr. Koch warned that this only reduced the intoxicating effect of alcohol, not completely eliminated it, so moderate drinking is still the key to staying healthy.
