During the treatment of H. pylori, there are no fruits that cannot be eaten clinically, and patients should pay attention to balanced nutrition and avoid overly stimulating foods such as chili peppers and hot pots. Once infected with Helicobacter pylori, patients are prone to peptic ulcer, chronic gastritis and other digestive diseases. There are generally no fruits that patients cannot eat during the treatment period, and they should pay attention to a light diet. Patients should eat more food containing protein as well as more vitamins, such as milk, carrots, oranges and so on. These foods can replenish the energy needed by the body and improve the body’s resistance, which is beneficial to the recovery of the disease, but when consumed in excess, they may aggravate the burden on the stomach and intestines, so they are not recommended to be consumed in excess. When patients are positive for Helicobacter pylori, they should avoid eating food that is too cold, stimulating and spicy to prevent stimulation of the gastric mucosa, leading to further aggravation of the condition. Once the patient is positive for H. pylori, it is recommended to consult a doctor in time for further examination and choose the appropriate medication for treatment according to the actual condition under the doctor’s guidance.
