A matter of taste: food preferences may be influenced by our unique ‘tongue prints’

Analysis of 3D images reveals the organ’s bumps and grooves are as personal as fingerprints

Whether they are long and slimy, wide and bumpy, fissured, furry or tied – our tongues may be even more unique than we give them credit for.

An analysis of 3D images of human tongues suggests that each of us may have a unique “tongue print” just as we have individual fingerprints. The research could help to shed new light on why people’s food preferences can be so varied, and assist in the design of healthier, yet delicious, alternatives to fatty or sugary foods.
