Dietary Phytochemical Index and Metabolic Markers in 600 Adults with Obesity

600 adults with obesity (BMI ≥ 30 kg/m²) were evaluated in a cross-sectional study linking dietary phytochemical intake to metabolic health. The dataset likely contains fasting blood measurements for glucose, insulin, HOMA-IR, lipids, CRP, IL-6, TNF-α, LBP, adiponectin, and TMAO. Author Lingtao Zheng published the raw data on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Modeling associations between dietary phytochemical intake and insulin resistance based on HOMA-IR values.
• Analyzing correlations between the Dietary Phytochemical Index (DPI) and inflammatory markers like CRP and TNF-α.
• Investigating the mediating role of TMAO in the relationship between diet and metabolic disturbances.
• Building predictive models for metabolic health outcomes using anthropometric and biochemical measurements.

Strengths

• Includes data from 600 participants, providing a substantial sample size for analysis.
• Contains a wide range of measured variables, including anthropometrics, dietary index, and multiple blood biomarkers.
• Data is openly available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The cross-sectional study design limits causal inference from the data.
