#526: Eating Rate, Food Texture & Satiation – Marlou Lasschuijt, PhD

Food science and behavior are intimately connected. One critical but often overlooked facet of this connection is food texture and its substantial impact on eating behavior and energy intake.

Food texture encompasses characteristics such as hardness and structure. It categorizes food into liquids, semi-solids, and solids, each with a wide range of textures—from dry and crispy to elastic and more substantial. This classification deeply affects how we consume food. The time it takes to chew and swallow a food item can vary greatly based on its texture.

Different textures can also influence the speed at which satiety signals are triggered. Eating rate is a highly individual trait, stable over time, and consistent across different contexts. Some people are naturally slower eaters, while others consume food quickly. This variance can have significant implications for energy intake and body weight.

In this episode, Dr. Marlou Lasschuijt, an assistant professor in the Sensory Science and Eating Behaviour group at Wageningen University, discusses the above topics and their implications.
