Food Texture Variability Within IDDSI Level 4 Categories

Variability data for food categories classified under IDDSI Level 4, which combines Extremely Thick (EX4) and Pureed (PU4) textures. The dataset is a 9.5 KB Excel file created by Muxi Chen and published on Figshare in April 2026. It provides quantitative measures of consistency within this specific dysphagia diet level.

Use Cases

• Analyze variability scores to identify which food categories show the most inconsistency within the IDDSI Level 4 classification.
• Compare the measured texture variability between different food categories listed in the dataset.
• Use the variability metrics to inform clinical guidelines for preparing and testing Level 4 dysphagia diets.

Strengths

• Dataset is openly licensed under CC-BY-4.0 for reuse.
• Focuses on a specific, standardized clinical framework (IDDSI Level 4).

Limitations

• Dataset is extremely small at 9.5 KB, indicating very limited scope and likely a small sample size.
• No column names, sample data, or row count are provided, limiting assessment of structure and completeness.
• Temporal and geographic coverage of the underlying data collection is unknown.
