Dextrin is a type of fiber. Soluble in water, and with a low viscosity, it should not negatively impact the mouthfeel of the beverage. Eating a diet rich in fiber can certainly have health benefits, says Blake. Because fiber stays in the stomach longer, keeping us feeling full, it can help decrease appetite, she says. And fiber attaches to some of the cholesterol in the digestive tract, preventing the body from digesting it and possibly helping lower blood cholesterol levels. But it isn't clear that a dose of fiber in a drink will provide those effects. That requires "a fair amount of fiber, and from multiple sources," says Blake. Suntory has not released nutritional information on Pepsi Special, nor disclosed whether it will be released in the United States.
