Infection with Helicobacter pylori
The bacterium Helicobacter pylori colonizes the surface of the gastric mucosa. It is able to survive in an acidic environment because it has developed specific mechanisms to withstand gastric acid. Up to 70 to 80% of adults may be infected. Transmission typically occurs via the fecal-oral route, contaminated food or water, or shared utensils. Infection most commonly takes place during childhood.
Dietary Approach for Helicobacter pylori
A diet high in fresh vegetables and fruits, particularly those rich in vitamin C, helps reduce the risk of H. pylori infection. An adequate concentration of this vitamin in gastric juice inhibits bacterial growth and limits the activity of the bacterial enzyme urease. General principles include eating frequent, small meals (4–6 times a day) spaced 3 to 4 hours apart, maintaining regular meal times, chewing thoroughly, and avoiding heavy, high-fat, and highly spiced foods.
Foods to Avoid in Helicobacter pylori Infection
Avoid foods and beverages that stimulate gastric acid secretion: alcohol, coffee, strong tea, spicy seasonings, fried foods, and carbonated beverages. Additionally, reduce high-fat products such as fatty meats, smoked fish, refined oils, margarine, and high-fat dairy (fatty cheeses, processed cheeses, and hard-boiled eggs). Sugar and sugary confectionery should also be strictly limited, as sugar creates an ideal environment for bacterial proliferation.
Recommended Foods in Helicobacter pylori Infection
Increase your intake of foods rich in vitamin A (carotenoids) and vitamin C. These include spinach, sweet potatoes, carrots, broccoli, apples, onions, and celery. These nutrients help protect the gastric mucosa and inhibit bacterial adhesion. Sulforaphane, found in cruciferous vegetables such as broccoli and cauliflower, also exhibits antibacterial properties. Stomach-soothing herbal teas like chamomile or licorice root, as well as garlic, oregano, and cranberry juice, can complement standard medical therapy.
