Study Finds Possible Link between Sugary Drinks, Cancer
People who drink a lot of sugary drinks have a high risk of developing cancer, researchers announced last week. However, the evidence cannot yet establish a direct connection between the two.
The researchers said the findings of a large study in France suggest that limiting the amount of sugar-sweetened drinks may help reduce the number of cancer cases.
Drinking sugary drinks has become more common worldwide in the last several decades. Sugar drinks are linked to obesity — the condition of being extremely overweight — which increases a person's cancer risk.
The study was published in the BMJ British medical journal. It looked at data from just over 100,000 French adults – 21 percent of them men and 79 percent women. The researchers noted how many sugary drinks each of them had, and followed them for up to nine years — between 2009 and 2018. The researchers measured their risk for all types of cancer, and some individual ones such as breast, colon and prostate cancers.
The researchers adjusted for other possible cancer risks in each individual, including age, sex, educational level, family history, smoking and physical activity levels.
The scientists found that a 100 milliliters increase in sugary drinks was linked to an 18 percent increased risk of overall cancer and a 22 percent increased risk of breast cancer.
The researchers looked at those who drank fruity juices and those who drank other sweet drinks. Both groups, they found, showed a higher risk of cancer overall.
For prostate and colorectal cancers, no link was found. The researchers said this might have been because there was only a limited number of cases of these cancers in the study group.
Experts not directly involved in the work said it was a well-run study, but noted that its results could not establish cause and effect.
Amelia Lake is an expert in public health nutrition at Britain's Teesside University. She said that while this study does not provide a definite cause and effect between sugar and cancer, it does add to the importance of efforts to reduce sugar intake.
"The message from the totality of evidence on excess sugar consumption and various health outcomes is clear," she said. "Reducing the amount of sugar in our diet is extremely important."
The researchers themselves also noted that the results would need to be repeated in future large studies.
The World Health Organization recommends that people should limit how much sugar they have to less than 10 percent of their total energy intake.
Many countries, including Britain, Belgium, France, Hungary and Mexico, have introduced or are about to introduce taxes on sugar with the aim of improving people's health.

研究发现含糖饮料与癌症之间可能存在关联
研究人员上周宣布，经常喝含糖饮料的人有很高的患癌风险。然而，目前还没有证据能证明两者之间存在直接联系。
研究人员表示，法国进行的一项大规模研究表明，限制含糖饮料的摄入量可能有助于减少癌症病例。
过去数十年来，饮用含糖饮料在全球日益普遍。含糖饮料与肥胖有关，肥胖指极端超重的状态，而肥胖会增加患癌风险。
这项研究发表在《英国医学期刊》上。该研究对超过10万名法国成年人进行了调查，其中21%是男性，79%是女性。研究人员记录了每名研究参与者的含糖饮料摄入量，并在2009年至2018年期间对他们进行了长达9年的追踪调查。研究人员衡量了参与者患上各类癌症以及乳腺癌、结肠癌和前列腺癌等特定癌症的风险。
研究人员还考虑了每名参与者可能面临的其他癌症风险因素，包括年龄、性别、教育水平、家族史、吸烟状况和身体活动水平等。
科学家发现，含糖饮料摄入量增加100毫升，总体患癌风险会增加18%，患乳腺癌的风险更是高出22%。
研究人员对饮用果汁饮品和其他含糖饮料的人进行了调查。他们发现，这两组参与者的总体患癌风险都有所增加。
研究发现含糖饮料与前列腺癌和结肠直肠癌没有关联。研究人员指出，这可能是因为研究小组中涵盖的这类癌症病例较少。
未直接参与研究的专家认为这项研究进展顺利，但同时指出研究结果可能无法建立因果关系。
阿米莉亚·莱克是英国蒂赛德大学的公共健康营养专家。她说，尽管这项研究没能提供糖分与癌症之间明确的因果关系，但确实增加了减少糖分摄入的重要性。
她说，“过量摄取糖分和各种健康结果研究的全部证据所传递的信息非常明确，即减少饮食中的含糖量极为重要。”
研究人员也指出，研究结果需要未来进行的大规模研究来验证。
世界卫生组织建议，人们摄取的糖分不应超过全部能量摄取的10%。
包括英国、比利时、法国、匈牙利和墨西哥在内，许多国家已开始或即将开始征收糖税，目的是改善民众健康。
