New scientific studies have shown more benefits for the Mediterranean diet And they’ve shown that it not only helps you lose weight, but also induces changes in gut health.
Researchers have shown that an intervention to increase adherence to the Mediterranean diet and an intensive weight loss program produces very beneficial changes in the gut microbiota after only a year. They have been verified by researchers from the Center for Biomedical Research on Obesity and the Nutrition Network (Ciberobn) -the Carlos III Health Institute-, the Rovira i Virgili University (URV) and the Hospital Virgen de la Victoria (University of Malaga) and his results are published in the American Journal of Clinical Nutrition.
Gut bacteria are the tiny living organisms in the large intestine of humans, which have been found to be important for maintaining good health, especially gut health, the research centers recalled.
The work was carried out within the framework of the “PREDIMED-Plus” study in which a group of participants followed a Mediterranean diet with energy restriction, physical activity and behavior changes, and another group of participants followed a Mediterranean diet with no calorie restriction, without any weight loss regimen. The results of the study are that participants who followed the Mediterranean diet and exercise recommendations lost more weight (4.2 kilograms) than participants who followed the unrestricted Mediterranean diet, who lost 0 , 2 kilo.
The beneficial effects of a healthy diet such as the Mediterranean are already well known, but scientists have observed that most previous studies have focused only on the effects of diet or physical activity on the individual gut microbiota. .
The new study looked at the Mediterranean diet with a different approach and thus verified that participants who followed the Mediterranean diet with calorie restriction lost more weight and reduced body mass index (BMI), waist circumference or blood sugar. They also lowered triglycerides and improved “good” cholesterol levels compared to the other group who ate a Mediterranean diet without any guidelines for weight loss.
The researchers explained that “oddly” the two groups increased grip to the Mediterranean diet, which has been observed with constant changes in the microbial genera that have been previously associated with the consumption of the Mediterranean diet. The increase in “good” microbial genera was also positively associated with the Mediterranean diet score in the general population.
The principal investigator of CIBEROBN and the University of Malaga, Francisco J Tinahones explained in the note that research centers have spread today that “the Mediterranean diet has shown to have prebiotic capacity, favorably modifying the bacteria in our intestines ”. And Jordi Salas, principal investigator of CIBEROBN and Rovira i Virgili University, clarified that “previous studies have been carried out on changes in the microbiota with the Mediterranean diet, but this is the first to compare the Mediterranean diet with a other Mediterranean diet. diet but low calorie producing weight loss ”.
The researchers stressed that future studies are needed to replicate these findings and delineate the mechanisms by which changes in the gut microbiota may have beneficial effects on the body. regulation of body weight and cardiovascular risk.
