Consume ultra-processed foods grow some bacteria related to inflammatory gastrointestinal diseases, according to research conducted by the Department of Human Nutrition of the University of Rovira i Virgili (URV) in Tarragona, which analyzed 641 patients at cardiovascular risk.
That workedpublished by Frontiers in Nutrition magazine, warns that the production and consumption of ultra-processed foods has increased exponentially in recent decades, and that eating these foods in excess sometimes leads to consumption high in sugar, salt and saturated fats.
In addition, according to the researchers Products that have gone through several industrial processes to which sweeteners, thickeners, colors or flavor enhancers are usually added.
Some scientific studies had already observed this These foods could alter the gut microbiota and they partially explained some of these adverse human health effects observed in prospective studies of large populations.
Now, URV researchers have found that eating this type of food is linked to a increased presence of bacteria specific to the human gut associated with inflammatory gastrointestinal diseases.
In the study analyzed 641 elderly people at high cardiovascular risk living in Reus (Tarragona), Barcelona, Valencia and Malaga.
They divided the patients into three categories depending on their consumption of ultra-processed foods – little, medium or much – and by analyzing their stool samples, they obtained information about the composition of their gut microbiota using high-performance computational methods.
Thus, the researchers saw that people who belonged to the group with high consumption of ultra-processed foods had a higher number of highly processed foods Bacteria associated with gastrointestinal diseases.
“These data suggest that the diet and nutritional status determinants of human health by changing the composition of the gut microbiota. “Detecting unhealthy dietary patterns related to gut microbiota profiles would be essential to understand the mechanisms of different diseases and to design future strategies to prevent and improve public health,” the researchers said.
