A study conducted by researchers from the Universities of Jaén and Granada has determined that high-fat diets cause bacteria to not respond to certain treatments.
The power of oil seems endless. Recently, a team made up of members of the Universities of Jaén and Granada They have confirmed that extra virgin olive oil regulates the functions of intestinal bacteria of the same genus and even of similar species.
The discovery made explains that a balance is established between very close strains, favoring them to present a less resistance to antibiotics and that produce fewer toxic compounds for the body during digestionThis has been conveyed by the team of experts who have operated under the protection and support of the Descubre Foundation.
One of the objectives of this research was to try to avoid digestive problems and to do this it is necessary to know how bacteria behave depending on the diet they are subjected to. All this knowledge has been captured in the article Intestinal microbiota modulation at the strain level by the olive oil polyphenols in the dietwhich was published in the magazine Frontiers in nutrition.
This was the great discovery about olive oil
A team of researchers made up of members of the universities of Jaén and Granada has confirmed that extra virgin olive oil regulates the functions of intestinal bacteria of the same genus, but also of similar species.
The team of experts has presented their progress in the prestigious magazine Frontiers in nutrition where they publish What is the genetic response and functioning of 75 strains of Enterococcus to different fats highlighting the prebiotic role of extra virgin olive oil.
These enterococci are intestinal bacteria with a great capacity for survival and are used as probiotics, but also in food fermentations that already favor the regulation of microbiotawhich are the set of bacteria that colonize the skin, the digestive system, including the mouth, and the genital system. What happens is that Some of these strains are responsible for infections that can be quite serious..
Natalia Andujara researcher at the University of Jaén, explains the importance of the discovery as follows: “Detailing each strain at a genetic level based on its diet makes it possible to establish measures to promote the proliferation of some or the reduction of others, depending on whether they are beneficial to the body or not.”

These works sought to find virulence factors in each strain to Knowing the colonization capacity of bacteria as well as the analysis of each of them in the production of certain compounds that can become toxic to the body. These are known as biogenic amines.
These strains fed with extra virgin olive oil showed less resistance to antibioticsless tendency to present virulence factors and did not participate in the dynamics of the rest of the isolates to produce more biogenic amines over time.
How was the experiment?
The study was carried out by separating the 75 strains of enterococci uniquely isolated from the faeces of twelve mice fed four different diets over a period of twelve weeks. Some rodents were fed a standard diet without added fats, while the rest were given the same diet plus a supplement of 20% butter in the first case, refined olive oil in the second and extra virgin olive oil in the third and last case.
The 75 isolates belonged to six different enterococcal species and were subjected to genetic profiling to ensure that the same strain was not isolated from the same mouse multiple times. A large analysis was then carried out, although no significant species-specific distribution was found between diets or times, although three of them were only present in the butter group and were responsible for some diseases such as diarrhoea, bacteremia or endocarditis.
