Evidence on the association between salt intake and gastric cancer is sparse.
In this study, researchers from Japan conducted a population-based prospective study to investigate this relation in a population where the majority are infected with Helicobacter pylori.
The team evaluated 18,684 men and 20,381 women aged 40-59 years between 1990 and 2001.
Subjects did not report any serious disease at baseline.

Subjects were asked to report their dietary habits.
The research team found that 486 subjects (358 men and 128 women) had histologically confirmed gastric cancer.
They determined that the quintile category of salt intake was dose-dependently associated with gastric cancer risk in men.
The team identified a clear association with salt and salted foods and risk. Frequency categories of highly salted foods such as salted fish roe and salted fish preserves were strongly associated with the risk in both sexes.
Dr Tsugane's team concluded, "Restriction of salt and salted food intake is a practical strategy to prevent gastric cancer in areas with high risk".
