Most of us are well acquainted with the five main tastes: sweet, savoury, salty, bitter and umami.
But did you know fat has also been identified as a taste, with its own unique receptors?
Fat doesn't provide the same distinct taste as sweet or salt. Instead, it elicits a sensation on the tongue.
And according to Professor Russell Keast from Deakin University's Centre for Advanced Sensory Science (CASS), the more sensitive you are to fat, the less of it you eat.
In other words, the more fat you can taste, the less likely you are to consume it.
This quiz was originally designed by a team of researchers from the University of Newcastle to measure fat intake.
But it's also a useful tool for measuring fat sensitivity.
Take this quiz to see how sensitive you are to fat, and what that says about your diet.
