Salt intake is closely related to cancer of the stomach and is likely to be an important pre-disposing cause.
In the high concentrations found in foods such as some instant soups and soy sauces, salt is a profound gastric irritant. It has been suggested that a high salt intake strips the lining of the stomach and may pre-dispose the individual to infection from the Helicobactor pylori bacterium.
Long-term Helicobactor pylori infection is considered a major risk factor for stomach cancer – it may lead to chronic inflammation of the inner layer of the stomach and possible pre-cancerous changes in the stomach lining.
Keeping our salt intake low may help reduce the risk of cancer of the stomach.
