The publish had greater than 2,700 upvotes on the time of this publication.
Via a Google key phrase search, Snopes discovered a number of information publications that wrote in regards to the examine the Reddit publish referenced, together with Information Medical Life Sciences, Newsweek, Know-how Networks, and Medical Information At the moment. The examine, “Including salt to meals at desk as an indicator of gastric most cancers danger amongst adults: a potential examine,” was printed within the peer-reviewed scientific journal Gastric Most cancers on April 17, 2024.
Researchers on the Heart for Public Well being, Medical College of Vienna analyzed the info of greater than 470,000 adults from UK-Biobank, a large-scale British biomedical database.

(An English-language model of the information launch can also be obtainable on the science information web site, EurekAlert.)
“Our outcomes additionally stood as much as the consideration of demographic, socioeconomic and way of life components and have been simply as legitimate for prevailing comorbidities,” examine creator Selma Kronsteiner-Gicevic mentioned within the information launch.
Researchers famous a number of limitations with their analysis. For instance, they might not consider the affect of sure traits similar to intercourse, age, ethnicity or smoking standing. It additionally was an observational examine, which implies different outdoors influences might not have been totally accounted for. As a result of the examine individuals volunteered, the findings can’t be generalized to the final U.Ok. inhabitants — or past — due to participation and age restrictions current with the UK Biobank cohort.
Whatever the limitations, the findings add to a rising physique of proof supporting salt’s potential position in gastroenterological cancers. For instance, analysis printed in 2009 within the World Journal of Gastroenterology discovered that salt might “trigger abdomen most cancers by way of immediately damaging gastric mucus” and that “appreciable proof” suggests limiting salted meals is a “sensible technique for stopping gastric most cancers”

As of this publication, abdomen most cancers is the fifth-most-common kind of most cancers worldwide, based on the World Most cancers Analysis Fund Worldwide. The company notes that there’s sturdy proof that consuming salt-preserved meals will increase the chance of abdomen most cancers.
Although the chance of abdomen most cancers will increase with age, consultants have famous a rise in gastrointestinal cancers, like these of the abdomen, liver, pancreas, and colon, in youthful individuals, notably girls.
