Die umfangreiche Studie ist die erste ihrer Art, die sich mit hochverarbeiteten Lebensmitteln und Unfruchtbarkeit bei amerikanischen Frauen beschäftigt. Frauen, die weniger hochverarbeitete Lebensmittel zu sich nehmen, haben eine höhere Wahrscheinlichkeit, schwanger zu werden. Der Zusammenhang bleibt auch nach Berücksichtigung von Alter, Gewicht, Lebensstil und anderen Gesundheitsfaktoren bestehen.

Researchers find link between ultra-processed foods and infertility in U.S. women
This massive study is a first-of-its-kind look at ultra-processed foods and infertility in American women.
Women who consume lower amounts of ultra-processed foods have higher odds of conceiving, according to new research from McMaster University. The link persists even after accounting for age, weight, lifestyle and other health factors.
Women reporting infertility consumed more ultra-processed foods, making up about 31 per cent of their daily intake, and scored lower on adherence to the Mediterranean diet, a healthy eating pattern rich in fruits and vegetables, whole grains and healthy fats.
The findings suggest that what we eat — and the degree to which it is processed — may influence reproductive health in a manner well beyond calories or weight.
For those interested, here’s the link to the peer reviewed journal article:

I still don’t think you can control for all variable, I suspect those that have more processed foods work longer hours in more stressful jobs. They probably don’t lead as healthy a lifestyle and go to doctors as often.
We need a better definition of UPF. What is it about UPF and that could be bad for human health? The article suggests the role of chemicals.
Are they chemical additives for flavour? Preservatives? Chemical contamination from packaging? Chemical changes that happen due to food processing techniques?
I appreciate the need to sound the alarm and raise awareness early. At the same time, a vague and overly general description makes it harder for people to find solutions. Not everyone has the time and money to eat whole and slowly prepared foods. As well, if the problem with UPF is something you still do with homemade foods (eg cooking fats at high temp, microplastic contamination from packaging) then you could still have the same problem with things like frying and barbecuing at home
So insulin resistance, endocrine disruptors like bisphenols, low grade inflammation due to compromised gut microbiome and low intake of some micronutrients and minerals can decrease women fertility.
tofu is an ultraprocessed food. this fearmongering really occluds core issue with food quality
if they can’t produce more poor people… that’s a problem
Good thing a single crown of broccoli is $5 right now at my grocery store. I had a great diet full of fresh foods before covid. Between shortages and price hikes, my diet looks nothing like that now, it’s awful.
It wouldn’t be out of the realm of possibility to consider phthalates in food packaging or other hormone disruptors
Did they also account the health of their partners? Wasn’t there another study recently, that said mens health has an influence on pregnancy anf birth?
I know this is science so I’m probably out of place but I have experience working with low income populations. I can specifically vouch for eating habits in these households being poor and falling into the UPF category. Despite that there does not seems to be any issue with fertility among these women. If anything, they are having more kids than planned. Again, anecdotal on my part but feels like we are missing something here.
Woo! Junk food over babies!!
This is really interesting. It seems like lower income families tend to have more children, and also consume the highest amounts of UPF considering its low cost. This study subverts that, so I wonder if the fertility is lowered nominally at most.
Well now I want to eat more UPFs
