AI Study Reveals Unique 'Tongue Prints', Paving Way for Personalized Nutrition and Early Cancer Detection

Researchers used AI to analyze 3D images of tongues, finding distinctive features that could predict age, gender, and individual identity with surprising accuracy.

• Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest.
• The research has huge potential for discovering individual food preferences, developing healthy food alternatives and early diagnosis of oral cancers in the future, experts say.
• The AI models were designed to gain a better understanding of individual features of the participant's papillae and to predict the age and gender of each volunteer.
• The AI tool could predict the type of papillae to within 85 per cent accuracy and map the position of filiform and fungiform papillae on the tongue's surface.
• Individuals could be identified with an accuracy of 48 per cent from a single papilla.
