Question

Quizplus · Accepted Answer

The breakdown products of prebiotics, such as fructooligosaccharides (FOS), galactooligosaccharides (GOS), and inulin, are not digested in the small intestine and can selectively stimulate the growth and activity of beneficial bacteria in the colon, such as bifidobacteria and lactobacilli. Therefore, D is the correct answer. A is incorrect because prebiotics are not strains of bacteria, but rather substrates that promote the growth of beneficial bacteria. B is incorrect because cottage cheese, kefir, buttermilk, and miso are sources of probiotics, not prebiotics. C is incorrect because probiotics should not cause infections or diarrhea if taken properly. E is incorrect because probiotics are live bacteria that can provide health benefits when consumed in adequate amounts.
