Test your knowledge with these top questions!
Probiotics, live beneficial microbes, help patients finishing antibiotics do what?
Broad-spectrum antibiotics cannot distinguish between pathogens and beneficial microbes. Probiotics help repopulate the depleted microbiome to prevent digestive issues.
Prebiotics, a type of dietary fiber, serve what primary function for probiotics?
Because human enzymes cannot digest prebiotic fibers like inulin, they travel intact to the colon where they act as a vital food source for beneficial microflora.
Derived from a Turkish word for 'feeling good,' what drinkable probiotic dairy beverage originated in the Caucasus Mountains?
Kefir is fermented using cauliflower-like "grains" containing a symbiotic culture of yeast and bacteria. Its Turkish root "keyif" means pleasure or good feeling.
Named for the milk sugar it ferments, what genus of probiotic bacteria is also responsible for the tart flavor of sourdough bread?
Lactobacillus breaks down lactose into lactic acid, which preserves fermented foods and creates the signature tangy flavor found in yogurt, pickles, and sourdough.
Prescription antibiotics destroy healthy gut bacteria, making probiotics useful to do what?
Antibiotics cannot distinguish between harmful pathogens and beneficial microbes. Taking a probiotic helps restore the healthy gut flora that the medication wipes out.
High-fiber prebiotics serve what primary function for the live probiotics inside your gut?
Prebiotics are non-digestible fibers that human bodies cannot break down, allowing them to pass intact to the lower gut where bacteria ferment them for energy.
Cooking fermented foods like sauerkraut at high temperatures does what to the probiotics?
Live probiotic cultures typically die at temperatures above 115 degrees Fahrenheit. To get the gut health benefits of sauerkraut, it should be eaten raw or unpasteurized.
Brewers create the probiotic drink kombucha by fermenting sweetened tea with what?
This culture is called a SCOBY, an acronym for Symbiotic Culture of Bacteria and Yeast. It consumes the sugar in the tea to produce the tangy, effervescent drink.
Dietary fibers known as prebiotics perform what main role for probiotics?
Because human bodies lack the enzymes to break down these complex carbohydrates, they reach the lower gut intact for beneficial microbes to metabolize.
Live probiotics prevent harmful bacteria from taking over the gut by doing what?
Through a mechanism called competitive exclusion, friendly microbes rapidly consume available nutrients and physically occupy binding sites on the intestinal wall.
