Don, would you like a cup of coffee? Yes, I would. Thank you, Yael. You know, Don, people really shouldn't like the bitter taste of coffee. Why do you say that?
Because scientists think that animals evolved the ability to detect bitter tastes in order to avoid things that are harmful or even poisonous. Could it be that people who like coffee are less sensitive to bitter tastes? Mmm, that would make sense, but it turns out that the opposite is true. In 2018, an international team of researchers reported that people who are more sensitive
to the bitter taste of caffeine actually tend to drink more coffee. The scientists used a large genetic database with data from more than 40,000 people. They studied three different genetic variants known to cause sensitivity to three different kinds of bitter substances, quinine, propyl thiouracil, and caffeine.
