In recent years, Dr. Jesús Álvarez-Herms has made significant strides in understanding the relationship between gut health, performance, and recovery in elite athletes. His research on the gut microbiome has provided groundbreaking insights into how the balance of intestinal flora can affect overall health and athletic performance. Particularly relevant is his work with top athletes like Kilian Jornet, where he has explored the physiological data collected during ultra-endurance events such as the UTMB 2022. Álvarez-Herms focuses on the connection between gastrointestinal health, gut dysbiosis, and the impact of nutrition on endurance performance, demonstrating how a well-balanced microbiota is crucial for elite athletes to perform at their peak​

What is Fecal Microbiota Transplantation (FMT)?

FMT involves the transfer of fecal microbiota from a healthy individual to a recipient with the goal of restoring their microbial balance. However, when this procedure is performed using the patient's own microbiota (auto-FMT), it eliminates the risks related to donor compatibility and potential adverse effects, offering a safer and more personalized option.

Auto-FMT is particularly useful after treatments that significantly disrupt the microbiota, such as antibiotic use or poor diet. This process aims to restore the microbiota to its optimal state, which can significantly impact an individual’s overall health.

Factors that disrupt the microbiota

Gut dysbiosis, or the imbalance of the microbiota, can be caused by several factors such as poor diet, sedentary lifestyle, physical and mental stress, and excessive antibiotic use. This imbalance has been linked to a variety of health problems, including intestinal inflammation, increased gut permeability, immune and metabolic dysfunctions, and neurological disorders.

Precision nutrition: The key to a healthy microbiome

Precision nutrition is based on the personalization of diet according to the microbiome, genetics, and lifestyle of each individual. This involves the inclusion of prebiotics, probiotics, and postbiotics, which are essential for maintaining a healthy microbiome. Prebiotics promote the growth of beneficial bacteria, probiotics introduce live microorganisms, and postbiotics are bacterial metabolites that influence health.

A diet rich in fiber and fermented foods like kefir and yogurt, combined with personalized supplements, can optimize the gut microbiota composition and improve not only digestive health but also the immune and metabolic systems.

Proactivity in health

One of the most innovative aspects of auto-FMT is its promotion of patient proactivity. Instead of waiting for health problems to arise, auto-FMT and precision nutrition encourage the adoption of healthy habits and proactive control over one’s health. This approach allows patients to become active participants in their well-being, restoring their microbiota and promoting active longevity.

Clinical applications and the future of FMT

Auto-FMT has shown promise in treating recurrent infections, inflammatory bowel diseases, and is being studied for its potential use in obesity, diabetes, autoimmune diseases, and even neurological disorders like autism.

Although this field is still developing, the creation of microbiota banks and standardization of procedures are essential steps to ensure that more people can access these treatments safely and effectively.

A promising future in precision nutrition

Auto-FMT, along with precision nutrition, opens up a new frontier in medicine, focusing not only on treating diseases but on preventing them and improving overall well-being. Personalizing treatments based on the individual microbiome is the future of health and wellness, and we are already seeing the first results in various medical fields.

Elite Athletes' Recovery

When we look at some of the world’s top athletes, like Kilian Jornet, who recently completed the challenge of summiting multiple peaks in record time, or Tadej Pogačar, who has demonstrated superhuman endurance by competing in both the Tour de France and the Giro d’Italia in the same year, we wonder: how do these athletes recover so quickly after such intense efforts?

One possible answer could lie in the field of advanced medicine and precision nutrition, where auto-FMT might play a key role in their recovery process. By restoring their gut microbiome to an optimal state after intense physical feats, these athletes could recover faster, reduce inflammation, and optimize their performance.
