NEW ORLEANS — Fiber has made a comeback, said Lu Ann Williams, director of innovation of Innova Market Insights. Previously linked to satiety and weight management, fiber is now seen as a key to a healthy gut microbiome. Forty-four per cent of U.S. consumers say they have increased fiber intake, Ms. Williams said. “If you looked at, say, ‘fiber 1.0’ in the U.S., it was really related to heart health and to cholesterol,” Ms. Williams said during a presentation at IFT19, the Institute of Food Technologists’ annual meeting and food expo, held June 3-5 in New Orleans. “And now 64% of U.S. consumers say they consume fiber for their digestive health.”
