High-salt foods can damage the protective layer of the gastric mucosa, increasing the risk of H. pylori infection. Examples include pickled foods, instant noodles, and potato chips.
Spicy foods can irritate the gastric mucosa, leading to mucosal damage and reducing its ability to defend against H. pylori. Peppers, chili, and Sichuan peppercorns fall into this category.
Consuming overly hot foods can damage the gastric mucosa, reducing its protective function and increasing the risk of H. pylori infection. Examples include hot pot and hot soup.
Smoked and grilled foods can become contaminated with H. pylori during preparation. Additionally, these foods often contain high levels of salt and fat, which can irritate the gastric mucosa.
Leftover food can produce nitrites and even spoil if stored for too long. Regular consumption of such food is not only unhealthy but can also increase the risk of H. pylori infection.
Ultra-processed foods typically contain high salt and high carbohydrates, which can damage the gastric mucosal barrier and increase the colonization of H. pylori.
