Just one glass of this drink a day may increase cancer risk
American researchers have identified a statistical link between daily consumption of sugary drinks and an approximately 2.5-fold increase in the risk of stomach cancer. Analysis of data from 112,284 adults showed that the risk significantly increased only with daily consumption, while moderate consumption showed no such association. Scientists emphasize the observational nature of the study and the lack of evidence for a causal relationship.
American researchers analyzed data from 112,284 adult participants in two long-term studies and found that daily consumption of sweetened beverages (soda, lemonade, fruit punch, sports drinks) is associated with an approximately 2.5-fold increase in the risk of stomach cancer. During the observation period, stomach cancer was diagnosed in 278 individuals. The risk significantly increased only with daily consumption of one serving (about 240 ml) or more; moderate consumption (several times a month or week) showed no such association. Women who consumed more than one serving per day had roughly a threefold higher risk. Diet drinks did not demonstrate a similar association. The study was observational, and the authors emphasize that the results indicate a statistical association, not a causal relationship. Senior author Dr. Andrew T. Chan, a gastroenterologist and epidemiologist, noted that this is the first study to identify such an association in a US population. The researchers considered possible mechanisms (weight gain, insulin resistance, chronic inflammation), but these were not tested within the scope of this work.
