Which of the following factors is NOT a standout risk factor for stomach cancer?

High fiber intake is not considered a standout risk factor for stomach cancer. In fact, evidence suggests that a diet rich in fiber may be protective against various types of cancer. High fiber foods, typically found in fruits, vegetables, and whole grains, contribute to overall digestive health and may reduce the risk of stomach cancer by diluting carcinogens and promoting healthy gut flora.

In contrast, obesity, atrophic gastritis, and diets high in salt or salt-preserved foods have been associated with an increased risk of developing stomach cancer. Obesity can lead to increased inflammation and hormonal changes that may contribute to cancer development. Atrophic gastritis, a condition characterized by chronic inflammation of the stomach lining, is a predisposing factor for stomach cancer due to the cellular changes that occur within the gastric tissue. Similarly, high consumption of salt and salt-preserved foods has been linked to an elevated risk of stomach cancer due to the potential for these foods to damage the stomach lining and promote the growth of carcinogenic microorganisms.
