Brief Summary

Lactose intolerance is a chronic disease caused by the total/partial lack of lactase production. When lactose is not properly digest, it is consumed by the microbiota. This situation presents different gastrointestinal symptoms such as meteorism, pain, bloating, diarrhoea and nausea. The dietetic treatment for this patients consists of avoiding lactose-rich foods, mainly milk and dairy products. However, nowadays exists a large diversity of lactose-free products specially focused on lactose intolerants. In this context, using B.coagulans as a probiotic in a food matrix could be an alternative for these patients, since its ability of spore forming and the production of beta-galactosidase. Based on the foregoing, the group research has design a randomized, double-blind, placebo-controlled crossover nutritional clinical trial to evaluate the effect of a regular probiotic with high production of beta-galactosidase effect over gastrointestinal syntoms of patients with lactose intolerance.

Outcome Measures

Primary Outcomes (1)

  • Gastrointestinal symptoms

    The questionnaire developed by Casellas et al. 2009 on the specific symptoms of lactose intolerance. The patient will indicate on a scale of 1 to 10 the intensity of the following gastrointestinal symptoms: abdominal pain, bloating, flatulence, diarrhea and cramps. The scale indicates the total absence of symptoms (0) or their severe presence (10).

Study Arms (2)

Lactase

ACTIVE COMPARATOR

Volunteers will consume once a day for 1 month a tropical juice (orange, mango, pineapple and turmeric) and a lactase tablet

Other: a Tropical juice with no probioticsOther: lactase tablet

Probiotic

EXPERIMENTAL

Volunteers will consume once a day for 1 month the probiotic added to a liquid matrix (tropical juice) and and a placebo tablet (cornstarch)

Dietary Supplement: Tropical juice with probiotics (B.coagulans)Other: placebo tablet (cornstarch)

Interventions

Once a day during all the intervention phase, volunteers with lactose intolerance should allow the spore-forming ability of B. coagulans in order to digest lactase from dairy products through regular consumption of Tropical juice with probiotics (B.coagulans)

Probiotic

Once a day during all the intervention phase, volunteers with lactose intolerance should consume a Tropical juice with no probiotics
