Study finds probiotics might not be as helpful for the intestine

The video discusses a study on probiotics, revealing that they often have little effect inside the body. Researchers created a probiotic cocktail using 11 types of bacteria, including Lactobacillus and Bifitobacteria, to test their colonization in healthy intestines. Participants were divided into two groups, one receiving the probiotic cocktail and the other a placebo. Results showed that in half the cases, probiotics passed through the body without effect, while in the other half, they temporarily colonized before being displaced by existing microbes.

What was the initial conclusion about the effect of probiotics inside the body?

• They have a significant positive impact.

• They completely replace existing microbes.

• They have little or no effect.

• They are harmful to the body.

What did researchers use to create their probiotic cocktail?

• Only Lactobacillus

• 11 types of bacteria

• 5 types of bacteria

• Only Bifidobacteria

Which bacteria were included in the probiotic cocktail?

• Streptococcus and Escherichia

• Clostridium and Enterococcus

• Lactobacillus and Bifidobacteria

• Staphylococcus and Bacillus

What was the purpose of giving half the participants a placebo?

• To compare with the probiotic group

• To ensure no one received probiotics

• To test the placebo effect

• To confuse the participants

What happened to the probiotics in half of the cases?

• They caused harmful side effects.

• They were expelled without effect.

• They improved digestion significantly.

• They permanently colonized the intestine.
