NCT05423015

Brief Summary

This study was a randomized, double-blind controlled protocol in children overweight aged 6-11 years. This study aimed to evaluate the effect of consuming fermented milk products containing Lactobacillus casei strain Shirota (LcS), as a probiotic enriched with prebiotic fructans from A. salmiana or inulin-like standard commercial prebiotic to improve the gut microbiota modulation. After providing detailed information, written informed consent was obtained from parents and written and oral assent from participants before the initial test day. Children were eligible for inclusion in the trial if they were overweight according to the World Health Organization (≥85th body mass index (BMI) percentile for overweight). The trial took place in three full-time elementary schools in San Luis Potosí, México, and the screening of the prospective participants took place up to 1 week prior to the randomization. Children were evaluated over a 6-week intervention period receiving different fermented milk products

Dietary Supplement: Lactobacillus casei strain Shirota plus fructans from A. salmiana

Interventions

Probiotic product were made in a Class II biosafety cabinet. Fifteen milliliters of the fermented milk food wich contains LcS were taken with a sterile syringe, and, at a subsequent time, 15 mL of sterile water were added to the probiotic product.

Also known as: L. casei Shirota, LcS, Probiotic product
