Content: Probiotics are defined as “live microorganisms which, when administered in adequate amounts, confer a health benefit on the host.” 1 This term refers to specific strains of bacteria, and typical probiotics include lactic acid bacteria such as Lactobacillus and Bifidobacterium. These strains are widely used in the fermentation of dairy products, such as yogurt, cheese and kefir. Fermented dairy products with active bacterial cultures are therefore one of the most common sources of probiotics. These types of probiotic-containing milk products may be beneficial for a number of gastrointestinal and digestive conditions. 2,3
The Evidence
Helicobacter pylori Infection
A 2009 systematic review and meta-analysis of randomized controlled trials evaluated the effect of fermented milk products enriched with probiotics on Helicobacter pylori infection. A total of 10 eligible studies, which included 963 adults and children, were assessed. It was found that fermented milk-based probiotic preparations reduce Helicobacter pylori infection rates by approximately 5% to 15%. 4
A prospective study published in 2012 examined the effect of probiotic-containing yogurt on systemic immunological response among 38 children with Helicobacter pylori infection. The study concluded that intestinal microbiota balance can be maintained and humoral and cellular immunity can be stimulated in children who regularly consume yogurt.
