Fat discrimination: A phenotype with potential implications for studying fat intake behaviors and obesity

► Fat is a nutrient sensed by oral, olfactory, and texture cues that adds palatability to many foods. ► There are no standardized procedures for studying oral fat perception. ► We developed a simple tool to measure the ability to discriminate fat content. ► Poor fat discrimination ability was linked to increased intake of added fats. ► This tool may be used to identify risk for obesity and excess fat intake.
