Beyond recommendations: implementing food-based dietary guidelines for healthier populations

Area of Science:

• Nutrition Science
• Public Health Policy
• Global Health Initiatives

Background:

• Diet-related diseases pose a significant global health burden.
• Current food-based dietary guidelines (FBDGs) have shown limited impact on human health.
• There is a need to harmonize efforts in developing and implementing FBDGs worldwide.

Purpose of the Study:

• To examine the concept of food-based dietary guidelines (FBDGs).
• To discuss the possibilities and challenges of harmonizing the development and implementation of dietary guidelines.
• To propose global harmonized efforts for more effective FBDGs.

Main Methods:

• Literature review and conceptual analysis of existing food-based dietary guidelines.
• Examination of the limitations in current nutrition science and FBDG development.
• Discussion of challenges including cultural diversity and socio-economic factors.

Main Results:

• The impact of FBDGs on human health has been limited despite contributing to understanding nutrients and foods.
• Current nutrition science has limitations, and FBDGs should consider the totality of dietary patterns, not just single nutrients.
• A unified global set of FBDGs faces challenges in addressing cultural diversity and complex interactions.

Conclusions:

• Harmonized global efforts are needed to support strategic dietary interventions and FBDG development/communication.
• FBDGs should be viewed as complementary to broader health-promoting interventions.
• Effective implementation requires addressing cultural, social, economic, and political complexities.
