Foods high in salt have been linked to an increased risk of stomach cancer, experts have warned. Stomach cancer, also known as gastric cancer, remains a major health concern worldwide, with dietary habits playing a significant role in its development.

In India, stomach cancer is one of the most common cancers in the southern region. It has become the second most common cancer in men and the third most common cancer in women in Asia.

According to a study, stomach cancer is decreasing but its burden is high in India. Doctors have advised that excess salt in the diet damages the stomach lining, making it more susceptible to infections such as Helicobacter pylori.

This bacteria is strongly linked to stomach cancer, and the combination of salt and infection may increase the risk.

Additionally, salt can increase the formation of carcinogens in preserved and processed foods. Experts have warned that most foods such as soy sauce, potato chips and processed meat have been linked to an increased risk of stomach cancer.

Dr Neeraj Dhingra, consultant in radiation and clinical oncology at Ruby Hall Clinic, Pune, said high salt intake can damage the stomach lining and increase the growth of Helicobacter pylori.

“Eating a balanced diet rich in fruits, vegetables and whole grains, as well as reducing salt intake, may help reduce risk,” Dr. Dhingra said.

Be careful of foods high in salt

Some foods are particularly high in salt and are associated with a higher risk of gastric cancer:

• Processed meats: Items such as bacon, sausage, and salami are often cooked with large amounts of salt.
• Pickled foods: Pickled and fermented vegetables are preserved in brine, making them high in sodium.
• Snack foods: Salt is added to potato chips, pretzels, and salted nuts to enhance flavor.
• Canned and packaged foods: Instant noodles, soups, and ready-to-eat meals often rely on salt for preservation.
• Soy sauce and spices: These are usually high in sodium and are used in large quantities in many recipes.

Dr. Bhavesh Patel, Consultant Gastroenterologist, Bhailal Amin General Hospital, said that excessive salt consumption can increase the risk of stomach cancer by 1.5 to 2 times.

“Salt not only damages the stomach lining but also promotes the formation of carcinogens in preserved foods,” he told IndiaToday.in.

How to avoid stomach cancer

To reduce the risk, experts recommend reducing salt intake:

• Cook Fresh: Prepare meals using fresh ingredients at home.
• Natural flavors: Use herbs, spices or lemon juice in place of salt.
• Check the labels: Opt for low-sodium packaged foods when possible.

Experts said that by making small, healthy choices daily, individuals can protect their long-term health.
