alert! Expert says excess salt could increase your risk of stomach cancer
Excessive salt intake may increase the risk of stomach cancer by irritating the stomach lining and promoting infections such as Helicobacter pylori, which can lead to cancerous changes. We contacted a health expert who explains how the risk can be reduced by making lifestyle changes such as a healthy diet, avoiding smoking and managing pre-existing conditions.

stomachor gastric, cancer Cancer is one of the most common types of cancer globally, and although its incidence varies by region, certain factors can substantially increase one’s risk. The disease develops in the lining of the stomach and can spread to other parts of the body. If left untreated, it can form a mass (tumor) and grow deep into the stomach walls. The tumor may spread to nearby organs such as your liver and pancreas. so What causes stomach cancer?However, researchers and health experts do not know exactly what causes stomach cancer cells to grow. But they do know some things that may increase your risk for this disease. One of them is excessive salt consumption. It has been found that excessive salt consumption irritates the lining of the stomach, making it more sensitive to cancer-causing agents. Research shows that high sodium levels can damage the stomach lining, causing chronic inflammation and increasing the chance of cancer.
We contacted Dr. Amit Javed, Director, Gastrointestinal Oncology, Fortis Memorial Research Institute, Gurugram, who explains that salt can cause breakdown of the mucosal layer of the stomach, making it more vulnerable to infection by Helicobacter pylori (H. pylori). Becomes more sensitive. The bacteria is strongly linked to stomach cancer. This chronic infection can lead to gastric ulcers, which can develop into cancerous lesions over time.
A study published in 2019 The Lancet found that high-salt diets were associated with a higher incidence of stomach cancer, especially in countries where salt consumption is extremely high. According to the World Health Organization (WHO), salt intake should be less than 5 grams per day to reduce the risk of cancer and other health problems like high blood pressure.
“Salty foods, such as preserved meats and spicy foods, may contain harmful substances such as nitrates, which are also linked to stomach cancer. High salt levels and the combination of these substances can further increase the risk of cancer. It is important to maintain a balanced diet with low salt intake to reduce the chances of developing colon cancer and promote overall digestive health,” he said.
Although there is no guaranteed way to prevent it, Dr. Amit shares several lifestyle changes and measures that can reduce the risk of colon cancer. This also includes:
1. Maintain a healthy diet
A balanced diet is important for gut health and overall well-being. A diet rich in fresh fruits, vegetables and whole grains is linked to a lower risk of colon cancer. Foods rich in fiber and antioxidants help protect stomach cells from damage. In particular, cruciferous vegetables like broccoli and Brussels sprouts, as well as fruits rich in vitamin C, have cancer-fighting properties. Also, limit your intake of processed and smoked foods, such as cooked meats and pickled items, as these contain nitrates and nitrites, which are linked to stomach cancer.
2. Avoid smoking and limit alcohol consumption
Smoking and heavy alcohol consumption are major risk factors for many types of cancer, including colon cancer. Smoking damages the stomach lining and increases the risk of gastric cancer, especially in the upper part of the stomach near the esophagus.
Excessive alcohol consumption has been linked to an increased risk of stomach cancer, as it can irritate the stomach lining and interact negatively with other risk factors.
3. Practice good food safety
Helicobacter pylori (H. pylori) infection is a well-established risk factor for stomach cancer. This bacteria is often acquired through contaminated food or water and practicing good food safety can help reduce the risk of infection. Wash fruits and vegetables thoroughly, avoid undercooked or unpasteurized foods, and drink clean, filtered water.
4. Monitor and manage pre-existing conditions
Certain conditions, such as chronic gastritis and peptic ulcer disease, may increase the risk of gastric cancer. Regular checkups can help detect early signs of abnormalities in the stomach lining. Early detection is important, because if detected early, precancerous changes in the stomach can sometimes be managed effectively.
5. Maintain a healthy weight
Excess weight, especially in the abdominal area, can increase acid reflux and irritation in the stomach lining, which can increase the risk of cancer over time. Regular exercise and a healthy diet can help maintain a healthy weight, which may reduce the chance of stomach and other gastrointestinal cancers.
6. Consider regular testing if you’re at high risk
In high-risk individuals, such as those who have a family history of gastric cancer or other genetic predisposition, regular checkups such as endoscopy can be a proactive way to monitor stomach health.
7. Limit the use of NSAIDs and painkillers
Frequent use of nonsteroidal anti-inflammatory drugs (NSAIDs) can irritate the stomach lining, increasing the risk of ulcers and, in some cases, stomach cancer. Although these medications are generally safe when used as directed, long-term use or high doses may have adverse effects. If you need to take these medications regularly, consult your health professional about safer alternatives or protective measures.
