Dietary Influence on Bacterial Vaginosis

Area of Science:

• Microbiology
• Nutrition Science
• Women's Health

Background:

• Bacterial vaginosis (BV) is a common vaginal infection linked to microbiota imbalance.
• A healthy vaginal environment relies on *Lactobacillus* species and low pH.
• Diet is an emerging, modifiable factor influencing vaginal microbiota and BV risk.

Purpose of the Study:

• To systematically review the relationship between dietary patterns and bacterial vaginosis (BV) risk.
• To investigate the impact of specific nutrients, food groups, and dietary habits on vaginal health.
• To identify potential dietary interventions for BV prevention.

Main Methods:

• Systematic review of existing literature.
• Analysis of dietary components including vitamins, minerals, fruits, vegetables, dairy, probiotics, carbohydrates, grains, and protein.
• Examination of diet's influence on vaginal microbiota composition and BV susceptibility.

Main Results:

• Vitamin deficiencies (A, C, E, D) may increase BV susceptibility.
• High intake of fruits and vegetables correlates with reduced BV risk.
• High-glycemic diets may promote BV; whole grains and fiber support a healthy vaginal microbiota.
• Probiotics and dairy show promise for *Lactobacillus* colonization; plant-based proteins may reduce inflammation.

Conclusions:

• Dietary patterns play a significant role in modulating vaginal microbiota and BV risk.
• Specific nutrients and food groups offer potential for BV prevention and management.
• Further research, including longitudinal studies and diverse population analyses, is needed to confirm causality and optimize dietary recommendations.
