Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Bacteria, specifically probiotic strains such as Lactobacillus acidophilus, Bifidobacterium, and Streptococcus thermophilus, are scientifically validated for their role in supporting individuals with lactose intolerance. Lactose intolerance results from a deficiency of the enzyme lactase, which is required to digest lactose, the sugar found in milk. Certain bacteria possess β-galactosidase (lactase) activity, enabling them to break down lactose in the gut. Multiple clinical studies have demonstrated that consumption of live-culture yogurts and probiotic supplements containing these bacteria can enhance lactose digestion and reduce symptoms such as bloating, gas, and diarrhea. For example, a meta-analysis published in the American Journal of Clinical Nutrition (2010) found that probiotic supplementation significantly improved hydrogen breath test results (a marker of lactose maldigestion) and reduced gastrointestinal symptoms in lactose-intolerant individuals. The beneficial effects are attributed to the bacteria’s ability to survive passage through the gastrointestinal tract and produce lactase, facilitating the breakdown of lactose within the intestines. While not all probiotic strains have this effect, and there is variability between individuals, the use of specific bacterial strains as an adjunct to dietary management is well-supported by scientific evidence. Therefore, the use of bacteria for this condition is not merely traditional but grounded in validated clinical research.
