SALT AND STOMACH CANCER
The association between salt and stomach cancer stems from the interaction between salt and the lining of the stomach. High salt intake can lead to the formation of certain compounds, such as nitrites and N-nitroso compounds, which are known to be carcinogenic, explains dietician Shruti K Bhardwaj. These compounds can damage the stomach lining over time, increasing the likelihood of developing cancerous cells. Also, salt can cause inflammation in the stomach, further contributing to the development of cancer.
The effects of excessive salt intake on gut health.
Adults should take salt less than 5 g/day or just under a teaspoon, as per the World Health Organization. Eating too much salt should be avoided, as it can have various negative effects on the gut health.
Ulcer
Excessive salt consumption can contribute to the development of conditions like gastritis and peptic ulcers by causing irritation and inflammation of the stomach lining. These conditions can lead to symptoms such as abdominal pain, bloating, nausea, and in severe cases, internal bleeding.
Hypertension and gut
High salt intake may increase risk of developing hypertension, which can damage blood vessels throughout the body, including those in the gastrointestinal tract, says Bhardwaj. This can lead to complications such as bleeding, ulcers, and ischemic bowel disease.
Dysbiosis
High salt intake can disrupt the balance of gut microbiota, leading to an overgrowth of harmful bacteria and a decrease in beneficial bacteria. This imbalance, known as dysbiosis, can impair digestion, weaken the immune system, and increase susceptibility to gastrointestinal disorders such as irritable bowel syndrome and inflammatory bowel disease, says the expert.
