Why can probiotic yogurt be useless for half of us?

Tens of thousands of us take a probiotic drink every day in the belief that it helps digestion

Eating a probiotic yogurt may be useless since half of us are "resistant" to friendly bacteria, according to a study

  • Tens of thousands of people drink a probiotic drink per day in the belief that it helps digestion
  • A new study suggests that they may be ineffective for more than half of those who drink them
  • It is said that probiotics contain "friendly" bacteria that help restore the natural balance of bacteria in the intestine.

Tens of thousands of us take a probiotic drink every day in the belief that it aids digestion.

But a new study suggests they may be ineffective for more than half of those who drink them.

It is said that probiotics contain "friendly" bacteria that help restore the natural balance of bacteria in the intestine.

It is said that they can reduce the symptoms of hay fever, prevent stomach errors in those traveling abroad and even prevent colds from lasting too long. In addition to beverages, they are often found in yoghurts.

But when 19 people in the study in Israel took probiotics containing 11 of the most common strains of bacteria, only eight had a "remarkable colonization" of their intestines by bacteria in probiotics.

Professor Eran Segal, of the Weizmann Institute of Science in Tel Aviv, said: "People have been very supportive of probiotics, even though the literature that underlies our understanding of them is very controversial.

Surprisingly, we saw that many healthy volunteers were resistant. Probiotics could not colonize their treaties. "

To test probiotics, volunteers received endoscopies (a tube from the mouth to the stomach) and colonoscopies (a tube along the large intestine) to extract and analyze the bacteria in their bowels.

It seems that many were & # 39; resistant & # 39; to probiotic beverages, and probiotic bacteria were "expelled" for its existing intestinal bacteria.

The authors say that it is likely that the number of people in the study who rejected probiotics will be reflected in a larger population.

They said: "This suggests that probiotics should not be universally given as a 'one size fits all' supplement.

"Instead, they could adapt to the needs of each individual." The results are published in the journal Cell.
