Measuring Dietary Botanical Diversity as a Proxy for Phytochemical Exposure

Area of Science:

• Pharmacognosy and nutritional science
• Microbiome research
• Human health and disease

Background:

• Pharmacognosy classifies medicinal plant properties but hasn't linked plant food diversity to gut microbiome function.
• Dietary phytochemicals impact gut microbial composition and host health through various mechanisms.
• Understanding these interactions is crucial for optimizing health through diet.

Purpose of the Study:

• To develop a novel metric, the botanical diversity index (BDI), for quantifying phytochemical exposure from plant food consumption.
• To propose the BDI as a tool for investigating the relationship between plant food diversity and gut microbial ecology.
• To bridge pharmacognosy and microbiome research for a deeper understanding of diet-microbiome-host interactions.

Main Methods:

• Development of the botanical diversity index (BDI) based on pharmacognostic principles.
• Utilizing established knowledge of phytochemicals and their effects on human health.
• Conceptual framework for applying the BDI to assess plant food diversity intake.

Main Results:

• The botanical diversity index (BDI) was successfully developed as a quantitative measure of phytochemical exposure.
• The study provides a rationale for using the BDI to analyze the impact of plant food diversity on the gut microbiome.
• The BDI offers a novel approach to link dietary patterns with microbial function and host health outcomes.

Conclusions:

• The botanical diversity index (BDI) represents a significant advancement in quantifying phytochemical exposure from diverse plant-based diets.
• The BDI framework facilitates research into the complex interplay between plant food diversity, gut microbiome composition, and host well-being.
• This approach has the potential to inform personalized nutrition strategies for improved health outcomes.
