Perspective: Framework for Developing Recommended Intakes of Bioactive Dietary Substances.

Area of Science:

• Nutritional Science
• Public Health
• Evidence-Based Practice

Background:

• Dietary bioactives, such as flavonoids and omega-3 fatty acids, offer health benefits beyond essential nutrition.
• Current information on dietary bioactives often lacks standardization and rigor, leading to consumer confusion.
• Evidence-based intake recommendations are needed for health professionals to guide consumers effectively.

Purpose of the Study:

• To present a framework for developing quantified intake recommendations for dietary bioactives.
• To ensure guidance is based on high-quality evidence, vetted for efficacy and safety.
• To facilitate the communication of specific dietary bioactive amounts linked to health benefits.

Main Methods:

• A 4-step framework adapted from clinical guideline development processes.
• Characterizing bioactives, their food sources, and intake levels.
• Evaluating safety, quantifying the bioactive-health relationship through systematic reviews, and translating evidence into intake statements.

Main Results:

• The framework provides a structured approach to quantifying dietary bioactive recommendations.
• It emphasizes the need for expert vetting of evidence for efficacy and safety.
• The process accounts for the unique consideration that side effects are unacceptable for dietary bioactives.

Conclusions:

• The proposed framework offers a model for credible health organizations to develop reliable dietary bioactive guidance.
• This approach supports evidence-based recommendations for specific dietary compounds and their health benefits.
• The framework is adaptable and can be updated with advancements in scientific approaches.
