Medical News Today (MNT)Daily Sugary Drink Consumption Linked to More than Double Stomach Cancer Risk

ℹ️ Observational Association Only Evidence

Investigators analyzed dietary and health data from more than 112,000 participants enrolled in the Nurses’ Health Study and Health Professionals Follow-up Study to examine whether sugar-sweetened beverage intake was associated with gastric cancer risk. Over follow-up, 278 participants developed gastric cancer. Compared with individuals consuming fewer than one sugar-sweetened beverage per month, those consuming these beverages daily experienced a substantially higher incidence of gastric cancer. Researchers also observed a relationship between higher fructose intake and greater gastric cancer incidence. Because this was an observational cohort study, the findings indicate an association rather than proof of a causal relationship. Potential confounders, including Helicobacter pylori infection, diet, obesity, smoking, alcohol use, and other lifestyle factors may contribute to the observed association.

Clinical Considerations

• Among more than 112,000 participants, investigators identified 278 gastric cancer cases during follow-up.
• Participants consuming at least one sugar-sweetened beverage daily had approximately a 2.45-fold higher risk of gastric cancer than those consuming fewer than one beverage per month.
• Higher intake of fructose was also associated with increased gastric cancer incidence.
• The association appeared particularly strong among women consuming more than one sugar-sweetened beverage daily.
• Artificially sweetened beverages were not associated with increased gastric cancer risk in this analysis.
• Limited information regarding Helicobacter pylori, an established gastric cancer risk factor, restricted assessment of potential confounding.

Practice Applications

• Interpret these findings as observational evidence that does not establish sugary beverages as a direct cause of gastric cancer.
• Recognize sugar-sweetened beverage consumption as one potentially modifiable exposure associated with multiple adverse health outcomes, including obesity and diabetes.
• Discuss gastric cancer risk within the broader context of known risk factors such as H. pylori infection, smoking, obesity, dietary patterns, and family history.
• Evaluate nutritional counseling opportunities for patients with high consumption of sugar-sweetened beverages.
• Monitor future prospective and mechanistic studies examining whether fructose-related metabolic pathways contribute to gastric carcinogenesis.
