A new study has shown that probiotics fight off obesity and inflammation as diets rich is fish oil produce different gut bacteria than those rich in lard.
Robert Caesar, first study author and field expert from the University of Gothenburg (Sweden) gave a statement saying that he and his colleagues “wanted to determine whether gut microbes directly contribute to the metabolic differences associated with diets rich in healthy and unhealthy fats”.
He went on to add that the team’s goal was to “identify interventions for optimizing metabolic health in humans”.
To reach their conclusions, the researchers took the gut bacteria of mice that had been put on diets rich is fish oil and transferred them into mice that had been put on regular diets. They also took gut bacteria from mice that had been put on regular diets and transferred them into mice that been put on diets rich is fish oil.
What they noticed is that the mice in the fist group benefited when the change was made, and the mice in the second group suffered when the change was made, even though both diets had the same amount of dietary fiber and the same energy content.
These results reinforce the theory that the number of calories consumed in a day is less important than the source of the calories. Caesar informed that dietary fiber is one of the main sources of energy for gut bacteria.
One interesting finding is that the mice that had been put on diets rich is fish oil did not experience inflammation and weight gain after the transfer was made. But the mice that had been put on regular diets did have those experiences.
What this means is that gut bacteria are independently linked to the excess weight and inflammation that occur when an individual adopts an unhealthy diet, and that probiotics have the potential to offset the harmful effects of such diets.
The researchers also found that eating lard increased the amount of Bilophila, gut bacteria that makes people vulnerable to gut inflammation, and that eating fish oil increased the amount of Akkermansia Muciniphila, gut bacteria linked to limiting weight gain and known for benefiting glucose metabolism.
Fredrik Bäckhed, senior author on the study, gave a statement of his own saying that the new study backs up previous studies which suggested that “the bacteria Akkermansia Muciniphila is a promoter of a healthy phenotype”.
But he went on to add that further research needs to be conducted in order to figure out how healthcare professionals can use probiotics to help people optimize their health outcomes.
The findings were published recently, in the journal Cell Metabolism.
