The Study
S1850 Positive Association of Dietary Salt Intake and Gastric Intestinal Metaplasia: A Systematic Review and Meta-analysis
This study looked at many other studies about salt and stomach problems. It found that people who eat more salt tend to have more stomach issues, but it can't prove salt causes the problems because other things might be involved.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
Eating too much salt might hurt your stomach lining and lead to changes that can turn into cancer later.

Eating a lot of salty preserved foods can hurt your stomach lining and cause long-term swelling, making you more likely to get stomach cancer after many years.
Eating more salt is linked to a higher chance of having a stomach condition called gastric intestinal metaplasia, which means your stomach lining changes in a way that might not be healthy.
Eating a lot of salt is linked to changes in your stomach lining that might lead to health issues, and many big studies show this connection is real even though the exact strength varies a bit.
Eating salty foods seems to be more strongly linked to early stomach changes that can lead to cancer than to actual cancer itself, meaning salt might affect cancer risk earlier in the process.
Eating salt doesn't seem to affect stomach changes differently in various parts of the world or in different types of studies—it's pretty much the same everywhere.
When researchers combined many small studies about salt and stomach changes, they found signs that the smaller studies might have problems or were more likely to be published if they showed certain results. This could make the overall results less reliable.
