Science: It’s Not Your Fault You’re Addicted To Carbs

It goes without saying carbs are happiness. Now scientists have found evidence that our tongues can register the starchy flavor of carbohydrate-rich foods as a primary taste, along with salty, sweet, sour, bitter, and Umami–the most recent flavor added to the list.

Juyun Lim, a co-author on the study, told New Scientist that this basic list doesn’t explain our love for stuffing our faces with fries: “Every culture has a major source of complex carbohydrate. The idea that we can’t taste what we’re eating doesn’t make sense.”

Because there are enzymes in our saliva that break down complex carbs into the shorter chains and simple sugars that they are built of, scientists have previously generally accepted the idea that humans detect starches by tasting sweet molecules. Lim and her team at Oregon State University tested this by giving volunteer participants solutions of dissolved carbohydrates containing long and short chains. “They called the taste ‘starchy’,” Lim said. “Asians would say it was rice-like, while Caucasians described it as bread-like or pasta-like. It’s like eating flour.” Participants were still able to taste this starchy flavor after being given lactisole, a compound that blocks the sweet receptors on our tongues. This is pretty solid evidence that starchy is a flavor of it’s very own.
