Core Viewpoint - A recent study published in the journal Nature Medicine indicates that approximately 15.6 million individuals born globally between 2008 and 2017 are expected to be diagnosed with stomach cancer in their lifetime, with 11.9 million cases (76%) linked to Helicobacter pylori infection [1][2] Group 1: Cancer Statistics - Stomach cancer is the fifth leading cause of cancer-related deaths globally, primarily caused by chronic infection with Helicobacter pylori, which is preventable through effective treatment [1] - The study predicts that 10.6 million new stomach cancer cases will occur in Asia, while sub-Saharan Africa, currently with a lower burden, is expected to see its burden increase to at least six times the 2022 estimates [2] Group 2: Prevention and Screening - The authors of the study advocate for increased investment in stomach cancer prevention, particularly through population-wide screening and treatment programs for Helicobacter pylori to reduce the global burden of stomach cancer [1] - The research suggests that implementing screening and treatment strategies could potentially reduce the predicted number of stomach cancer cases by up to 75% [2] Group 3: Data Limitations - The predictions made in the study are subject to limitations in data quality and coverage, especially in resource-poor areas where cancer registries may be incomplete or missing [2]

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]
