Daily Meal Plans for Chronic Conditions Derived from NHANES

215,135 daily meal plans for adults with nine chronic conditions, generated from 23,152 National Health and Nutrition Examination Survey (NHANES) participants spanning 2003 to 2020. Researcher LEI ZHAO created this dataset using a three-tiered computational pipeline to align meal plans with WHO and DRI dietary guidelines. The resource is provided in CSV and PostgreSQL formats to support chronic disease dietary research.

Use Cases

• Analyze nutrient intake patterns across meal plan levels (Gold, Silver, Bronze) for specific chronic conditions.
• Model relationships between participant health profiles and generated meal plan compositions.
• Train recommendation systems to suggest condition-specific meals using the NHANES food library and co-occurrence constraints.
• Validate the nutritional consistency of algorithmically generated (Bronze) plans against real-world intake records (Gold/Silver).

Strengths

• 215,135 daily meal plans provide a substantial basis for analysis.
• Data generation is based on 23,152 adult participant records from NHANES (2003-2020).
• Meal plans are structured with three quality tiers (Gold, Silver, Bronze) and linked to detailed health and nutrient profiles.

Limitations

• Meal plans are computationally generated, not directly observed dietary intake, which may not reflect real-world adherence.
• The dataset's geographic coverage is limited to the United States, as it is derived from NHANES.
• Specific participant-level column details are not provided in the input metadata.
