New Urine Test Accurately Profiles A Person’s Diet

January 12, 2017: 12:00 AM EST
British scientists have developed a five-minute urine test that can determine accurately whether a person is eating a nutritious diet or junk food. The test measures hundreds of biomarkers known as metabolites that appear in urine when red meat, chicken, fish, fruit and vegetables are digested. It measures how much fat, sugar, fiber and protein a person has eaten. The test was applied to urine samples in 291 participants from a previous study and found to accurately predict diet. The scientists say that the test will help dieters – whose food diaries are often inaccurate – properly record intake of unhealthy food as well as fruits and vegetables. Studies have shown that about 60 percent of people misreport what they eat to some extent.  [ Image credit: © Grook Da Oger  ]
