Ultra processed foods we damage our health, leading to a weight gain, altering hormones and even introducing in the organism of men, nocive substances for sperm, with repercussions on fertility. We already knew that these foods hurt, but this study provides further scientific confirmation with details before not entirely known or demonstrated.
What are the ultra processed foods and where they are found
The Nova classification system groups foods based on their degree of processing: group 1 includes unprocessed or minimally transformed foods, such as fresh meat and vegetables, while 4 includes ultra-planned, containing industrial and synthetic ingredients that are difficult to recognize on supermarket shelves.
The latter are industrially produced by using processes such as molding, extrusion and pre-peak, which help food producers to introduce these synthetic ingredients in standardized foods and series products. These ingredients and processes contribute to reducing costs, increase the duration of conservation and improve the flavor of food.
An ultra processed food is a food or a drink that contains at least one ingredient that does not exist as such in nature or in our handouts – explain the experts of the French magazine 60 Millions de Consommateurs – this is called ultra -transformation marker (Mut)
Muts are above all food additives, but in reality not only: they are ultra -processed foods also refined fats, extracts and natural aromas, synthetic aromas, as well as steed and glucose syrup.
We do not always realize how many ultra -prompt foods are offered and in what frequency, but examples of these foods are everywhere, from sugary cereals for breakfast to hot dogs, from sugary drinks to flavored yogurt, but also i Cordon Bleu And the breaded fish, as well as the cooked vegetables jumped in a pan, just to name a few.
The risks to health
And in recent years there is also increasingly talking about the health risks of those who consume them with a certain frequency. In fact, not a few studies have connected them to different problems and even to increase the risk of premature death.
According to a study published about a year ago on The Lanceta diet rich in ultra -reprocessive foods increases the risk of cardiovascular diseases. The research, which lasted over 30 years and conducted on 200 thousand people, had shown, in particular, that those who consume more ultra -prompt foods have a greater risk of 16% of developing coronary diseases than those who consume less.
New research
A revolutionary study conducted now has discovered that ultra-processed foods lead to an increase in weight, alter hormones and introduce harmful substances linked to the drop in the quality of the sperm. The results also indicate that it is precisely the nature processed to make foods harmful to cardiometabolic and reproductive health.
Over the past 50 years, obesity and type 2 diabetes rates have increased dizzyingly, while the quality of the sperm has collapsed. To guide these changes could be the growing popularity of ultra-processed foods.
To obtain as accurate data possible, the scientists finally compared the impact on the health of unpublished and ultra-procepsed diets on the same person: for this reason they recruited 43 men aged between 20 and 35 years old, who followed each of the two diets for three weeks, with three months of “Washout” between one and the other.
In particular, half of men started with the ultra-procepsed diet and the other with the unpredictable one. Half of men also followed a hypercaloric diet with 500 more daily calories, while the other received the amount of normal calories for their build, age and level of physical activity, without revealing them which diet were following. Both the unplugated and ultra-processed diet presented the same amount of calories, proteins, carbohydrates and fats.
The results
Our results show that ultra-processed foods damage our reproductive and metabolic health, even if not consumed in excess-explains Jessica Preston, co-author of the research-this indicates that it is the processed nature of these foods that make them harmful
Scientists have in fact discovered that people increase in weight with an ultra-processed diet compared to a minimally transformed diet, even with the same calories taken: the volunteers have in fact taken about 1 kg more of fat mass during the ultra-procepted diet compared to the unpublished diet, regardless of the fact that they followed a normal or hypercaloric diet, and also several other health indicators. cardiovascular have been influenced.
The study also revealed that a diet rich in ultra-processed foods introduces higher levels of pollutants, already known to influence the quality of the sperm.
Scientists also discovered in those who had followed an ultra-processed diet a worrying increase in the level of Ftalato Cxminp, a substance that alters hormones and that is used in plastic. Confirming the suspicions, the men who followed this diet have also found a decrease in testosterone levels and follicle-stimulating hormone, crucial for the production of sperm.
We were shocked by how many bodily functions were altered by ultra-processed foods, even in young and healthy men-comments Romain Barrès, who led the study-the long-term implications are alarming and underline the need to review the nutritional guidelines for better protection from chronic diseases
