Yogurt for diarrhea.
A daily serving of yogurt reduces the incidence and duration of
antibiotic-associated diarrhea, reported Dr. Ripudaman S. Beniwal of
Indiana University, Indianapolis, and associates.
In the first randomized, controlled trial of yogurt to prevent
antibiotic-associated diarrhea in an acute care setting, patients
consumed 227 g (8 oz) of vanilla-flavored yogurt with active cultures of
Lactobacillus acidophilus, L. bulgaricus, and Streptococcus thermophilus
twice daily for a mean of 6.6 days. After a mean follow-up of about 7.5
days, a significantly lower percentage of patients who ate yogurt had
diarrhea (13 of 105, 12.4%), compared with control patients (23 of 97,
23.7%). Among the patients who developed diarrhea, the yogurt group had
significantly fewer total days with diarrhea, compared with the control
group (23 vs. 60 days). Yogurt has its effects by either maintaining the
normal intestinal microflora that are otherwise reduced by antibiotics,
or enhancing the host immune response, the investigators suggested (Dig.
Dis. Sci. 48:2077-82, 2003).
