Taste buds might determine what foods taste delicious to you and which end up politely spit out in a napkin, but a new study proves that it's possible to physically alter the way you taste certain foods—specifically those pesky bitter ones that can be hard to swallow but offer so many health benefits. Think antioxidant-rich dark chocolate, vitamin-packed radicchio, and nutrient-loaded dandelion greens.
Researchers at Purdue University and the U.S. Department of Agriculture recently found that the proteins in saliva connected to flavor can be modified by eating bitter foods. Throughout the course of the study, researchers asked participants to drink chocolate almond milk three times a day for a week and rate its bitterness (cocoa is a naturally bitter ingredient if left unsweetened).
After the participants consumed the milk, researchers found that the protein composition of their saliva had changed and was comprised of more proline-rich proteins known to bind the sharp flavor compounds in chocolate. As these proteins increased, the participants noted that the milk was less bitter. Essentially, they found that the more bitter foods you eat, the more you'll enjoy the way they taste and want to add more of them to your diet.
"By changing your diet, you might be able to change your flavor experience of foods that at one point tasted nasty to you," according to Cordelia A. Running, PhD, in a press release about the study.
This is big news for anyone who avoids bitter vegetables due to their harsh taste, especially when so many can be beneficial to the body. Charles Passler, MD, (nutritionist to the likes of Bella Hadid and Adriana Lima) tells MindBodyGreen that bitter veggies can do wonders for your digestive system. They activate cells in the stomach that aid acid, bile, and digestive enzyme production, which all boost digestion and can help detoxify the liver.
