What Should Be Considered in Diet When Infected with Helicobacter Pylori?

Infection with Helicobacter pylori can lead to a variety of gastric diseases, including chronic gastritis, peptic ulcers, and even gastric cancer. Numerous studies have shown that over 90% of duodenal ulcers and approximately 80% of gastric ulcers are caused by H. pylori infection. For individuals already infected, dietary choices play a crucial role in managing the condition and supporting recovery.

A well-balanced diet is essential for patients. It's recommended to consume easily digestible foods that provide sufficient calories, proteins, and vitamins. Examples include porridge, noodles, milk, soft rice, soy milk, eggs, and lean meats. These foods are gentle on the stomach and help maintain proper nutrition without causing additional irritation.

Including high-vitamin foods like fresh vegetables and fruits is also beneficial, as they support immune function and promote healing. However, it's important to avoid fibrous or coarse foods that may be difficult to digest, such as celery, leeks, bean sprouts, ham, preserved meats, dried fish, and whole grains. While these items are generally healthy, they can stimulate excessive gastric secretion and place added stress on the digestive system. If properly processed into purees or softer forms, they may be consumed occasionally.

Steer clear of irritating and hard-to-digest foods, including fried dishes, spicy condiments, and overly acidic, sweet, salty, hot, or cold foods. Items like broth, raw onions, raw garlic, concentrated fruit juices, coffee, alcohol, and strong tea should be avoided, as they can trigger acid production and worsen symptoms. Additionally, pickled foods containing nitrates or nitrites should be limited due to their potential carcinogenic effects—especially when combined with an H. pylori infection, which itself increases the risk of stomach cancer.

Preventing transmission within households is another key consideration. H. pylori often spreads among family members, so adopting hygienic eating habits is vital. Using serving chopsticks, practicing individual portioning, and regularly disinfecting utensils can significantly reduce the risk of cross-contamination. Parents should especially avoid chewing food before feeding it to children, as this practice greatly increases the chance of bacterial transmission.

Maintaining good dietary hygiene is critical during treatment. By making thoughtful food choices and following safe eating practices, individuals can support their recovery and reduce the likelihood of reinfection or complications associated with H. pylori.
