论文作者指出，这些预测估计受到数据质量和覆盖范围的限制，特别是在资源匮乏的区域，癌症登 记不完善或缺失。尽管如此，他们呼吁全球努力加强预防和监测胃癌，以遏制这一疾病蔓延。 在本项研究中，论文第一作者兼共同通讯作者、国际癌症研究机构Jin Young Park和同事合作，调 查了2022年185个国家胃癌发病率数据，并结合了联合国人口数据中的队列特异性死亡数据开展预测分 析。 他们预测，若不采取干预措施，全球出生于2008-2017年间的人口中将有1560万人在一生中被诊断 出胃癌，其中1190万人(76%)可归因于幽门螺旋杆菌感染。同时，预测有1060万例新增胃癌将发生在亚 洲，相比之下，尽管撒哈拉以南非洲目前胃癌负担相对较低，但预测未来负担将至少是2022年估计值的 6倍。 不过，此次研究在模拟分析人群水平的幽门螺旋杆菌筛查和治疗策略的影响时，研究人员发现，预 测胃癌病例数量可减少多达75%。 中新网北京7月8日电 (记者 孙自法)施普林格·自然旗下专业学术期刊《自然-医学》北京时间7月7日 夜间发表一篇癌症研究论文认为，2008-2017年全球出生的人口中，预计有1560万人可能在一生中某个 时候患上胃癌 ...

Core Viewpoint - The article emphasizes the importance of dietary habits and lifestyle choices in maintaining gastric health, highlighting specific foods and behaviors that can harm the stomach and offering recommendations for protection. Group 1: Foods to Avoid - High-salt foods can irritate the gastric mucosa and increase the risk of gastritis and potentially gastric cancer, with a recommendation to limit salt intake to under 5 grams per day [4] - High-sugar foods can disrupt gut microbiota balance and are linked to functional dyspepsia, with a suggested daily sugar limit of 25 grams [6][5] - Smoking and drinking alcohol can lead to gastroesophageal reflux disease and are associated with an increased risk of gastric cancer; it is advised to limit alcohol intake to no more than 15 grams per day [7][9] - Poor dietary hygiene can lead to Helicobacter pylori infection, a significant factor in various gastric diseases, with recommendations for proper handwashing and food safety practices [9] - Certain medications, such as aspirin and ibuprofen, can damage the gastric mucosa, and it is advised to consult a doctor before use [10] Group 2: Recommendations for Gastric Health - Increasing the intake of fresh fruits and vegetables can provide essential nutrients and antioxidants that protect gastric health, with a recommendation to fill half of each meal with vegetables [12] - Regular consumption of soy products is beneficial due to the presence of isoflavones that may induce apoptosis in gastric cancer cells [14] - Eating in moderation and chewing food thoroughly can help reduce gastric burden, with a suggestion to eat until 70-80% full [15] - Maintaining a healthy weight is crucial, as obesity is linked to an increased risk of gastric cancer; BMI should be monitored, with specific thresholds for overweight and obesity provided [16]
