Researchers at Mass General Brigham reported this week that adults who drank at least one sugar-sweetened beverage per day showed substantially higher rates of gastric cancer than those who rarely consumed them. The finding comes from decades of tracking data rather than a short-term trial. For a cancer that has received relatively little dietary study, the result fills a meaningful gap.
What the Study Measured
The analysis drew on more than 112,000 U.S. adults enrolled in the Nurses’ Health Study and the Health Professionals Follow-Up Study, both of which have collected dietary information over several decades.
Participants consuming one or more sugary drinks daily showed roughly 2.45 times the gastric cancer risk of those drinking less than one serving monthly. The association held after adjusting for other risk factors. Published in Gastro Hep Advances, the findings were reported by The Hill and other outlets this week.
Beverages counted in the sugar-sweetened category included:
- Regular carbonated soft drinks
- Fruit punch and lemonade
- Sports drinks
- Other non-diet sweetened beverages
Artificially sweetened drinks showed no comparable association.
Why Gastric Cancer Specifically
Stomach cancer ranks among the leading causes of cancer death worldwide, yet diet has been studied far less here than for colorectal or breast cancer. Researchers identified total fructose intake as a factor worth further examination.
This fits a broader pattern in nutrition research. Findings on ultra-processed foods and chronic disease have pointed toward similar mechanisms involving metabolic strain and inflammation.
What the Findings Do Not Show
Observational studies identify associations. They do not establish cause.
People who drink several sodas daily may differ from those who don’t in ways the adjustments cannot fully capture. The authors have been direct about this limitation, and reporting that presents the result as proven causation overstates it.
Placing It Alongside Other Evidence
Sugar-sweetened beverages have been linked previously to liver, breast, and colorectal cancers. The gastric finding extends that line rather than opening a new one.
Research on the effects of ultra-processed food provides useful context, since beverages sit within a larger category of products that has drawn sustained research attention.
Cardiovascular researchers have followed a comparable path. Work on cardiovascular disease prevention moved from single-nutrient studies toward whole-pattern analysis over several decades.

What This Means Practically
Roughly two-thirds of American adults report drinking a sugar-sweetened beverage daily, which makes the exposure widespread rather than unusual.
A single study rarely changes clinical recommendations on its own. It does add weight to guidance that already existed.
If you have questions about how findings like these apply to your own circumstances, a physician or registered dietitian can offer guidance grounded in your history.
