Food 'fingerprint' test developed

17th January 2012

UK researchers have created a way to identify the food a person has consumed through the use of a urine dipstick.


The researchers, from Newcastle and Aberystwyth, have called the food "fingerprint" test a "lie diet-detector" and could be used to identify the cause of diseases.

The food "fingerprint" test is able to show which foods have been consumed and how much has been eaten.

The researchers said the food "fingerprint" test is so accurate it can even show if a person has eaten white, red or processed types of meat.

The food "fingerprint" test uses chemical "fingerprints" called metabolites, which have been identified for salmon, raspberries, orange juice and broccoli.

A spokesman for Aberystwyth University said: "What we eat has a big impact on our health but it is very difficult to measure exactly what, and how much, people eat in everyday life - and people find it difficult to record honestly.

"Measuring what people eat can help prevent illness by showing definite links between particular kinds, and amounts, of foods and specific diseases. By testing urine for the chemical "fingerprints" of different foods, the scientists' recent research demonstrated that they could determine whether individuals are eating healthy diets or not."
