Blood and urine particles may reveal the amount of energy that a person consumes Useful foodsA new study found that there is an essential step to understand the effect of products that make up approximately 60 % of the American diet.
This is the first time that scientists have determined biological signs that can indicate a height or less than foods, which are associated with A set of health problems, Erikka Lovfield, a researcher at the National Cancer Institute, said the study Posted on Tuesday In Plos Medicine.
“It can give us some clues about what the basic biology may be between the Ultra -treated and healthy food association,” said Luftfield.
Ultra -treated foods – sugary grains, soda, chips, frozen pizza and more – are products through industrial processes with ingredients such as Addresses and colors And preservatives that are not found in home kitchens. They are everywhere in the United States and other places, but studying their health effects is difficult because it is difficult to follow what people eat precisely.
Typical nutrition studies depend on the summons: asking people about what they ate during a certain period. But such reports are unreliable because people do not remember everything they eat, or they record them inaccurately.
“A more objective procedure and possibly also needed a more accurate procedure,” explained by Loffeld.
To create new grades, Loftfield and her colleagues examined data from a current study of more than 1,000 older adults who were members of Aarp. More than 700 of them have provided blood and urine samples, as well as detailed food summons reports, collected over a year.
Scientists have found that hundreds of interlocations – digestive products and other processes – correspond to the percentage of energy consumed by a person from highly treated foods. From these, they created a degree of 28 blood marks and up to 33 urine sign that reliably predicted eating highly treated food in people who consume typical meals.
“We have found this signature, which was a kind of prediction of this diet that suffers from a high -treatment height and not just a specific food item here and there, she said.
A few signs appeared, especially amino acids and carbohydrates, at least 60 times from 100 test repetitions. The study found that one of the signs showed a possible link between a high diet in high -treated foods and type 2 diabetes.
To confirm the results, Loftfield measured the registration tool with participants in a national study of the National Institutes of National Institutes of Ultimate Foods that are carefully controlled.
In that study, 20 adults to live for a month at the National Institutes Center. They have received diets from superolor and unprocessed foods that are compatible with calories, sugar, fat, fiber and large nutrients for two weeks each and they were told to eat as they love.
Loftfield found that they could use the scalp to see when individual participants were eating a lot of high foods, and when they did not eat these foods.
Loffield said the results indicated that the signs are “valid on the individual level.”
Dr. Dariush Mozavary, Director of the Institute for Medicine at the University of Tafs, who did not participate in the study, said that it is still early research, but determining the signs of blood and urine to predict the packing of very treated foods “offered a great scientific.”
He said: “With more research, these metabolic signatures can begin to break the biological paths and damage in UPF and also differences in the health effects of the specific UPF food groups, treatment methods and additions.”
Loftfield said she hopes to apply the tool to current studies where blood and urine samples are available to track, for example, the effect of high food consumption on the risk of cancer.
At a time when government research support is reduced, funding remains uncertain.
She said. “How can we finance studies that must be done to answer these questions in time?”
