Ultra-verarbeitete Lebensmittel schaden die Gesundheit der Männer. Sie erhöhen das Gewicht, stören Hormone, verringern Testosteron und führen schädliche Substanzen ein, die mit der sinkenden Spermienqualität verbunden sind. Sie enthalten industrielle und synthetische Zutaten. Dies mag der Grund sein, warum die Spermienqualität in den letzten 50 Jahren gesunken ist.

I’ve linked to the press release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
Not all calories are equal: **Ultra-processed foods harm men’s health**
A groundbreaking human study has found that **ultra-processed foods lead to increased weight, disrupt hormones and introduce harmful substances linked to declining sperm quality**. The findings indicate that it is the processed nature of these foods that makes them harmful to cardiometabolic and reproductive health
**Over the past 50 years, rates of obesity and type-2 diabetes have soared, while sperm quality has plummeted**. Driving these changes could be the increasing popularity of ultra-processed foods, which have been linked to a range of poor health outcomes. However, scientists still aren’t sure whether it’s the industrial nature of the ingredients themselves, the processing of the foods, or whether it’s because they lead people to eat more than they should.
The scientists also discovered a worrying increase in the level of the hormone-disrupting phthalate cxMINP, a substance used in plastics, in men on the ultra-processed diet. **Men on this diet also saw decreases in their levels of testosterone and follicle-stimulating hormone, which are crucial for sperm production**.
Isn’t it basically all due to weight? IiRC obesity is a major cause of hormone imbalance and sperm quality reduction.
It may be likely that the simple act of gaining such weight, and holding it, would be leading to all these health problems. Not any specific ingredient.
I’m pretty sure I’ve read elsewhere that the most likely cause is how much time we spend sitting now vs. how we lived prior to industrialization. The testes hang down away from your body so that they can be cooler than our natural body temperature. Tight underwear and sitting down all the time prevent that, thus counteracting the evolutionary design and reducing sperm production.
This is most likely just one factor of the problem. Others might be a far more sedentary life and work, more pollution of new types such as endocrine disruptores like BPA, PFAS, lead, aluminium, and tons of other stuff plus social factors plus stress from a changing society and so on and so on
Id love for one of these „ultra processed foods“ studies to use like beyond meat and tofu and protein powder and other ultra processed foods that dont already also belong to the highly caloric, highly paltable group of foods we’ve known were bad for us forever. Ultra processed seems like a nonsense category to me and focusing on seems like its how we get people thinking beef tallow fries and cane sugar soda are the secret to health.
And yet governments will willfully limit or allow increase cost ls of weight loss drugs even to private health users. Big UPF are in charge.
And here I thought that other study said that cats are carriers of a parasite that decapitates sperm, suggesting that this might be the main reason for sperm quality.
Also. Be wary of “healthy” or meat alternatives as they are in fact highly processed foods: ex. mixed protein bars and impossible brand ‘meats’.
So if the claim/conclusion is the food does that, does it do all that irrespective of weigh gain and sedenrarity?
Or is the actual conclusion „obesity and sedentarity harm health?“
I’d hope to assume they controlled for that, but I wouldn’t be so sure
Does bread fall into that category
2 years ago my husband was experiencing general malaise, so we did some health monitoring that included getting a continuous glucose monitor.
It turns out that the pre-packed “grilled chicken sandwich” he was buying nearly everyday at work was spiking his blood sugar like crazy, way way way more than home made pizza, pasta, freshly baked bread, etc.
This was so eye opening for us because we saw for the first time how freaking potent all of those nasty preservatives are. If you grill a piece of chicken and put it between 2 slices of freshly baked bread, it is a COMPLETELY different food from some pre packaged sandwich that appears the same from say, the airport.
I don’t know the mechanisms but we can speculate that this “ultra processed” food is already so processed and broken down by chemicals that it hits our bloodstreams in a mad rush, leading to metabolic issues and ill health from inflammation. I’m sure there is more to the story, too.
Any food you make at home with butter, salt, flour, even sugar is so superior to whatever these Frankenstein foods are.
We eat al dente pasta all the time now with pasture raised pork and fresh veggies etc, and we have lost weight and feel so much better than when we were eating convenience “health” foods.
I’m gonna be honest, this is yet another example of **most likely** being overweight impacting everything else.
Being overweight disrupts hormones and decreases testosterone. Doesn’t matter if you eat ultra-processed foods or fruit. If you are overweight, odds are higher that you will experience these problems.
