The study, conducted at the University of Kentucky School of Medicine, looked at questionnaires from 175 people who were, on average, 52 years old.
They found supertasters were the least likely to incorporate vegetables into their diet.
“We’re talking a ruin-your-day level of bitter when they tasted the test compound. These people are likely to find broccoli, Brussels sprouts and cabbage unpleasantly bitter; and they may also react negatively to dark chocolate, coffee and sometimes beer,” Smith said.
While about 25% of people are “supertasters,” another quarter of the population are known as “nontasters.” These are the people who have two of the AVI variant and tend to have no sensitivity to bitter foods, researchers say.
Researchers say they intend to continue to look for new ways for people with this genetic makeup to incorporate heart-healthy vegetables in their diet, in a much more enjoyable way.
