Probiotic milk products are valued mainly because the active bacteria they contain do what in the intestine?
AReplace the need for any digestive enzyme fully
BIncrease the count of every harmful intestinal microbe
CStop the digestion of food in the intestine entirely
DMaintain the balance of intestinal microorganisms
Answer & Solution
Correct answer: D. Maintain the balance of intestinal microorganisms
1. Probiotics carry active bacteria like Lactobacillus and Bifidobacterium.
2. They maintain the balance of intestinal microorganisms.
3. They raise helpful microbes and lower harmful ones, so increasing harmful microbes is wrong.
4. They support, not stop, digestion, ruling out the remaining choices.
