Blood and urine tests can now reveal how much ultraprocessed food someone eats, thanks to new research. Scientists at the National Institutes of Health (NIH) used machine learning to find hundreds of metabolites linked to processed food consumption. Erikka Loftfield, a researcher at the National Cancer Institute in Maryland, explained that they created a “biomarker score” that predicts ultraprocessed food intake based on these metabolites.
The study initially gathered data from 718 older adults who shared blood and urine samples and detailed their diets over a year. The research team then ran a smaller clinical trial with 20 adults. For two weeks, participants consumed a diet rich in ultraprocessed foods, followed by two weeks on a diet devoid of them.
This breakthrough test is the first to measure ultraprocessed food intake using blood and urine samples, according to Fox News Digital. The findings, published in PLOS Medicine, highlighted how metabolites in serum and urine correlated with the energy percentage from ultraprocessed foods. This new approach aims to address inaccuracies often found in self-reported dietary questionnaires.
In the study, scientists utilized machine learning to pinpoint metabolites associated with processed food intake. Loftfield expressed surprise at discovering that these metabolites are involved in various biological pathways, showing the complex effect of diet on metabolism. Ultraprocessed foods, as defined by the NIH, are typically industrial products that are high in calories but low in essential nutrients.
Chronic illnesses such as obesity and various cancers have been associated with diets heavy in ultraprocessed foods. While the study showed promising results, the researchers noted that the method still needs more validation before it can be widely used. They emphasized the need for further research across different age groups and dietary habits.
Loftfield pointed out that “metabolite scores should be evaluated and improved in populations with different diets and a wide range of UPF intake.” This method holds potential for future studies linking processed food consumption to chronic diseases. For those concerned about their ultraprocessed food intake, checking ‘nutrition facts’ labels for added sugars, saturated fats, and sodium is a practical step.
The research underscores the significant impact of ultraprocessed foods on health, as noted by conservative outlets like Fox News and Newsmax. Reducing intake of these foods could align with broader scientific research on maintaining a healthy diet. This study marks a step forward in understanding the dietary influences on health and disease prevention.
As the research progresses, there may be more insights into how ultraprocessed foods affect our bodies. This innovative test could pave the way for improved dietary guidelines and health recommendations. Keeping an eye on food labels and making informed choices remains a key strategy for those looking to reduce their consumption of ultraprocessed foods.
