It is commonly said that “we are what we eat,” but in recent years, the relationship between our mind and our digestive system has begun to take on a new meaning.

This connection not only refers to the foods we consume but also to the complex community of microorganisms that resides in our gut, known as the gastrointestinal microbiome.


Healthy Aging

A recent analysis has revealed that certain prebiotic supplements may positively influence the memory of older adults. Researchers emphasize that the studied supplements, inulin and fructooligosaccharides (FOS), are “affordable and easily accessible.”

These compounds belong to the category of dietary fiber, which are components of food that our body cannot digest on its own. Generally, this fiber passes through our digestive system without significant alterations.

However, there are specific types of fiber that are metabolized, not by our digestive system, but by the bacteria that reside there. Prebiotic foods serve precisely to nourish these beneficial microorganisms.

Quince: the fruit with high fiber content that is rarely consumed.



Study with Twins




In this study, 72 individuals participated, grouped into 36 pairs of twins, predominantly women, all over 60 years old. Each twin was randomly assigned to a group: one experimental and one control.

The twins in the experimental group received a powder supplement that combined fibers and proteins, while the control group received a placebo that contained only proteins.



Improvements in memory.

The results showed that the twins in the experimental group scored higher on the memory test compared to the control group. Although it was investigated whether there were changes in the muscle mass of the participants, these results did not show significant differences.

The findings of the study were published in the journal Nature Communications, which adds legitimacy to the research.


Exploring the Microbiome




The relationship between fiber supplement intake and the improvement of cognitive functions may be linked to the prebiotic capacity of these compounds. Researchers noted a change in the composition of the gut microbiota, highlighting an increase in bacteria of the Bifidobacterium genus, which are considered beneficial for health.

The idea that our microbiome may have extensive effects on our health is not new.

Previous studies have suggested a connection between gut health and brain function, as observed in research that related fasting methods to alterations in gut microbiota and changes in brain activity.

Despite these advances, there is still much to learn about the mechanisms underlying these relationships. Understanding these processes is essential to identify the true causal connections.

There is increasing evidence highlighting the importance of microorganisms inhabiting our bodies, beyond pathogens, and their crucial role in our health and well-being.
