A long-term study involving over 112,000 U.S. adults found that those who drank at least one sugar-sweetened beverage daily had about 2.45 times the risk of developing gastric cancer compared to those who rarely consumed such drinks. The findings, published in Gastro Hep Advances, highlight a possible link between daily intake of sugary drinks and an increased risk of stomach cancer. However, researchers emphasize that the study does not prove that these drinks cause cancer, only that a connection exists. Artificially sweetened beverages were not linked to a higher risk of gastric cancer. The research, conducted by scientists at the Mass General Brigham Cancer Institute, used data from two long-running studies: the Nurses' Health Study and the Health Professionals Follow-Up Study. These studies have tracked participants' diets, lifestyles, and health for many years. Over the course of the study, 278 participants were diagnosed with gastric cancer, allowing researchers to analyze patterns in their beverage consumption and other factors. The study found that the link between sugar-sweetened beverages and gastric cancer risk was present in both men and women. Among women in the Nurses' Health Study, those who drank more than one sugary beverage daily had a 3.04 times higher risk of gastric cancer compared to those who rarely consumed them. Additionally, researchers observed that higher overall fructose intake—often from these drinks—was associated with a greater incidence of gastric cancer. Researchers also investigated whether Helicobacter pylori (H. pylori), a bacteria known to increase the risk of stomach cancer, might explain the findings. However, they found no connection between sugary drink consumption and H. pylori infection. The study's predominantly white participant pool also limits the ability to determine if the association varies across different racial and ethnic groups. As an observational study, the research can identify patterns but cannot confirm that sugar-sweetened beverages directly cause gastric cancer. Other factors, such as diet or lifestyle, could also play a role in the higher cancer rates observed. Despite this, the study's large sample size and detailed data over many years allowed researchers to account for many other potential risk factors. More research is needed to confirm these findings and understand the possible mechanisms behind the observed association.
