Can probiotics help the guts of frail elderly on liquid diets?

This study looked at whether taking a probiotic supplement for 30 days could change the types of bacteria and the production of helpful fatty acids in the gut of frail elderly patients who get all their nutrition through a feeding tube at home. Researchers compared patients who took the probiotic to those who did not, checking their stool samples for changes. The goal was to gather information to see if probiotics might be beneficial for this specific group.
