How much I-ulsaprocessed food do you eat? Blood record and irine
A new study suggests blood and urine samples can provide a goal-measured diets and help unrelvel their disease connections
Diet rich in the handsome good go with a lot of health conditions.
Urinary and blood molecules may reveal what a man’s large food from ultra-processed formas, according to a study published in Plos medicine today. The paper suggests that these measurements provide a purposeful way to keep track of the ultra-processed process – and can be used for investigations such as diabetes and cancer.
Ultra-processed foods manufactured by industrial substances, such as additives and emulsifiers, not usually found in food cooked. From the sweet yogurts of factory-made factory and fragmented snacks, “it’s a wide range of foods”, as an epidemiologist at the US National Cancer Institute in Rockville, Maryland.
Studies associated with high consumption of ultra-processed foods in the ultra-process of an increased risk of fatness, cardiovascular disease, diabetes and some cancers. But these investigations usually depend on asking people to remember what they eat, which is unreliable.

Studies also show the potential to study metabolism products released by blood and urine, but only for small metabolites. Loftfield and his companions now expand analysis to include more than 1,000 metabolites, made if the body converts to eat energy.
“This work is important,” said Oliver Robinson, a molecular epidemiologist of Imperial College London. “There are many errors in measuring traditional evaluations for dieting.”
Diet scoring
Loftfield and his companions studied samples collected from 718 healthy individuals aged 50-74 in 2012-13. The urinary and blood samples of participants were collected twice, six months apart. Participants also asked – up to six times during a year of study – to record all that they consumed in the day before. Ang koponan sa Loftfield Labin sa matag butang nga pagkaon, gikan sa bun sa usa ka burger ngadto sa hiwa sa keso, karne sa karne ug ketchup, bisan sa Ultra-processed o dili sa ultra-processed o dili sa ultra-processed o dili sa ultra-processed o dili sa ultra-processed o dili sa ultra-processed o dili sa ultra-processed o dili sa ultra-precessed o dili sa ultra-precessed or not ultra-precessed or not ultra-precessed or not ultra-processed or not.
Researchers use a machine learning technique to give each participant a score for some of their daily energy consumption, says the Loftfield. They know that, on average, the process processed by ultra-ultra of 50% to intimidate enertor strength, but the range is different between individuals – from 12%. Individuals consuming most ultra processes usually obtain their strengths from carbohydrates, additional sugars and satured fats and fibered by proteins and proteins in ultra-prosased proteins.
Researchers immediately examined blood samples and urine samples, looking for metabolites that are more common to people that foods with many ultra-processed foods.
Samples from people with diets rich in selected foods are processed especially with metabolite in an increased risk of a molecule made with some food packages. They also contain smaller metabolites obtained from fresh fruits and vegetables.
Randomized study
To test if metabolite scorite is available to predict the presence of many selected foods to a person who has been processed by a diet without ultra-processed food in two weeks in the same diet in the opposite range. The Loftfield and his companions learned that they met the difference between two diets by looking at metabolites in urine and blood samples.
The Loftfield wants to try the way populations with many different diets, and to young people, with many foods processed ultra. He hopes to use the tool to improve affiliation studies between ultra-processed food and ultra cancer.
Robinson thinks if the tool is used to solve unanswered questions, including what is about ultra-processed foods that are not good for you. It is difficult to identify between metabolic signature of a rich food in ultra-processed food and one that is bad in salt, sugar and saturated fats, he said.
Understanding this difference can help companies improve their products. “We have been trapped in this industry system in the industry where we all eat ultra-processed food, and it is very difficult for new people to return to fresh food, because our food systems have been resurrected,” Robinson added.
