Traveler’s Diarrhea According to several studies, it appears that regular use of acidophilus and other probiotics can help prevent “traveler’s diarrhea (a disease caused by eating contaminated food) 4.12 A study that evaluated 820 people traveled to southern Turkey, where the use of a probiotic called Lactobacillus GG significantly protected against intestinal infection. Other studies have found similar benefits, including a placebo-controlled trial included 3,000 Austrian travelers. The great benefits were seen in travelers who visited North Africa and Turkey. Researchers realized the benefit depending on the consistent use of the product, and a dose of 1,000 mg daily was more effective than 250 mg daily. Infectious diarrhea. The evidence suggests that probiotics can significantly reduce the duration of diarrhea and perhaps help prevent it. The evidence is stronger with the probiotic Lactobacillus GG and infection with a particular virus called rotavirus.
For example, a double-blind placebo-controlled trial of 269 children (ages 1 month to 3 years) with acute diarrhea found that those treated with Lactobacillus GG was recovered more quickly than those who were given placebos. The best results were seen among children with rotavirus infection (Rotavirus is a virus that can cause severe diarrhea in children). Similar results with Lactobacillus GG were seen in a double-blind study of 71 children. In addition, a double-blind study evaluated the potential benefits of probiotic L. reuteri in 66 children with rotavirus diarrhea. The study found that treatment shortened the duration of symptoms, and the higher the dose, the better the effect.
