A study reveals that ultraprocessed fattening more

An international team of scientists has discovered that people gain more weight with an ultraprocess diet than with a minimally processed diet, even with the same amount of calories. The study also revealed that a diet rich in ultraprocessed foods introduces higher levels of pollutants that affect the quality of sperm, according to their authors in the magazine Cell metabolism.

“Our results show that ultraprocessed foods harm our reproductive and metabolic health, even if they are not consumed in excess. This indicates that it is the processed nature of these foods that makes them harmful,” he says Jessica Prestonmain author of the study, who conducted the research during her doctorate at the NNF Center for Basic Metabolic Research (CBMR) of the University of Copenhagen (Denmark).

To obtain the best possible data, scientists compared the impact on the health of unprocessed and ultra -processed diets in the same person. They recruited 43 men from among 20 and 35 yearswhich dedicated three weeks to each of the two diets, with three months of rest between them.

Half began with the ultraprocess diet and the other half with the unprocessed. The other half of the men also received a high calorie diet with 500 calories daily additional, while the other half received the normal amount of calories for their size, age and level of physical activity. They were not informed what diet they followed. Both the unprocessed and ultraprocessed diet had the same amount of calories, proteins, carbohydrates and fats.

Men increased approximately 1 kg more fat mass With the ultraprocess diet compared to the unprocessed diet, regardless of whether they followed a normal or excessive diet. Several other cardiovascular health indicators were also affected.

Scientists also discovered a worrying increase in the CXMinp Fthalate level, a hormonal disruptor and a substance present in plastics, in men who followed an ultraprocess diet. These men also experienced a decrease in its testosterone levels and stimulating follicle hormonecrucial for sperm production.

“The amount of bodily functions impacted us Affected by ultraprocessed foods, even in healthy young men. Long -term implications are alarming and highlight the need to review nutritional guidelines for better protection against chronic diseases, “says the main author of the study, the teacher Romain Barrès, of the NNF Center for Basic Metabolic Research of the University of Copenhagen and the University Côte d’Azur (France).
