People badume that probiotics and prebiotics are safe, but French researchers said Monday that there was very little research to prove it.
The data indicates whether products work the way people believe they do, other researchers have noted. Despite the growing market of probiotics, it is difficult to prove that they are safe or effective.
Probiotics – products that provide bacteria allegedly useful to the gut – have been around for hundreds or even thousands of years. Yogurt is an example, with its high dose of Lactobacilli and Bifidobacteria. Prebiotics are similar products that aim to grow and grow so-called good bacteria.
Research on the microbiome shows that the collection of bacteria, yeasts and perhaps viruses in the body affects human health.
Aida Bafeta of the French Inserm Research Institute and her colleagues examined 384 separate studies on prebiotics, probiotics and symbiotics – products that include both. – Done since 2015.
Most research teams just seemed to badume that the products were safe, Bafeta and his colleagues reported in the Annals of Internal Medicine.
"One third of the tests gave no information on the damage, and only 2% adequately reported the main safety components."
"We can not usually conclude that these interventions are safe without the safety data being communicated. "
Dr. Shira Doron, of the Tufts University School of Medicine, is one of the few researchers to have examined the safety of probiotics
.It is true, she says, that there are not many adverse effects in healthy people.But it There have been, especially in hospitalized patients
"If you are immunocompromised, or if you are undergoing chemotherapy or neutropenia – you have a dangerously low number of white blood cells – or your gut is leaking for any reason Doreno told NBC News, "it is obvious that if you had any managed probiotics, they could get into your blood. "
Bacteria found in the intestines can cause damage if they enter the bloodstream, a bacteremia.
Another potential risk is for people taking probiotics to try to counter the damage done by antibiotics. The World Health Organization has pointed out that in theory, living bacteria could provide genes for antibiotic resistance to infectious bacteria in the body, even though this has not been demonstrated.
Probiotics could also stimulate the immune system, but that's another
It can be dangerous to badume that taking doses of bacteria, even if they are supposed to be beneficial, is safe for all world in all circumstances, warned the Bafeta team
