Helicobacter pylori infection is the most common bacterial infection in humans and its prevalence is much higher in low-and middle-income countries (around 80-90% among adults) than in high income countries (<40%). H. pylori infection can not only impact nutrient uptake and utilisation, but also increase the risk of gastritis, peptic ulcers and stomach cancer.
