(PRESS RELEASE) LUXEMBOURG, 7-Aug-2026 — /EuropaWire/ — The Luxembourg Institute of Health, known as LIH, has opened registration for CAROFIBER, a new nutrition study designed to investigate how common food components interact during digestion and influence nutrient absorption. Through the project, researchers aim to better understand how everyday dietary choices and food combinations can affect the nutritional value of meals. The CAROFIBER project has been launched to move beyond theoretical models and examine how these interactions occur in real human digestion. He said the insights gained from volunteers will help researchers determine which specific food combinations provide the greatest nutritional benefits.
