Ultraprocessed foods affect reproductive and metabolic health regardless of the amount of calories that are consumed compared to an unprocessed food diet, indicates a study with men published by Cell Metabolism.
Ultraprocesses cause weight gain, alter hormones and introduce harmful substances related to the decrease in sperm quality, says the article signed by French and Danish researchers.
A rich and very processes -free diet causes excessive calorie consumption, but scientists were not sure if it is due to the industrial nature of the ingredients themselves, to the processing of the foods that lead people to eat more than they should.
The study shows that ultraprocesses harm reproductive and metabolic health, even if they are not consumed excessively. “This indicates that it is the processed nature of these foods that makes them harmful,” said Jessica Preston, from the University of Copenhagen and one of the signatories of the article.
The research compared the impact on the health of unprocessed and outraged diets in the same person, for which 43 men between 20 and 35 years were recruited, who followed each of the two for three weeks, with a three -month rest period between them.
One half began with the ultraprocess diet and the other unprocessed. One group received with 500 additional calories per day and the other the amount necessary for their size, age and level of physical activity, but they did not know which one they were following.

Ultraprocessed foods alter hormones
In each group, the amount of calories in the outraged diet and the little processed was the same. This experimental protocol allowed to dissociate the effect of excessive calorie consumption of the effect of the diet itself, explained the French National Center for Scientific Research (CNRS) in a statement.
The men won around 1 kilo more fat mass with the ultraprocess diet compared to the unprocessed one, in addition there was an increase in body mass and the relationship between LDL and HDL cholesterol, which is an indicator of cardiovascular risk.
In addition, the decrease of two hormones involved in metabolism and male fertility (GDF-15 and FSH, respectively) and the quality of the sperm also tended to deteriorate, with a decrease in the number of mobile sperm.
The complexity of industrial processes, the addition of additives and the multiplication of the stages of preparation of ultraprocessed foods automatically increase the risk of pollution by industrial pollutants, which could influence the harmful effects of this food on health.
Scientists also discovered a worrying increase in CXMinp Fthalate levels, a substance used in plastics that alters hormones, in whom they followed an outrageous diet.
“We were surprised by the amount of bodily functions that were altered by ultraprocessed foods, even in healthy young men,” in the words of Romain Barrés, CNRS and another of the signatories.
Long -term implications, “he said,” are alarming and highlights the need to review nutritional guidelines to protect better against chronic diseases. “
