Using nutrition to help recovery from infections

Area of Science:

• Microbiology
• Nutritional Science
• Gastroenterology

Background:

• Antibiotics are crucial for treating infections but can disrupt the gut microbiota.
• This disruption may lead to gastrointestinal issues and serious conditions like Clostridioides difficile infection.
• Nutrition significantly influences gut microbiota diversity and function.

Purpose of the Study:

• To review current evidence on dietary strategies for mitigating antibiotic-induced gut dysbiosis.
• To explore the role of nutrition in managing infections and supporting gut microbiota recovery.

Main Methods:

• Literature review of studies investigating the impact of diet on gut microbiota during antibiotic therapy.
• Analysis of research on specific nutrients and dietary patterns (e.g., high-fiber diets).

Main Results:

• Beneficial nutrients support the gut microbiota-host symbiosis, reduce inflammation, and maintain gut barrier integrity.
• Short-chain fatty acids improve immune response and decrease C. difficile infection severity.
• High-fiber diets promote faster gut microbiota recovery post-antibiotics.

Conclusions:

• Nutrition plays a vital role in managing infections and counteracting antibiotic-induced dysbiosis.
• Emerging evidence supports personalized nutrition for restoring microbiome diversity.
• Further research is needed to identify optimal nutrient combinations for microbiome restoration.
