Data Sheet 1_Anti-inflammatory diets and mental health: a scoping review of randomized con

A scoping review by Meredith L. Sprengel, published on figshare in April 2026, synthesizes evidence on anti-inflammatory diets and mental health. The review identified 42 randomized controlled trials and 23 systematic evidence syntheses from searches conducted through February 2025. It summarizes findings on the effects of dietary patterns like the Mediterranean diet on outcomes including depression and anxiety.

Use Cases

• Conducting a meta-analysis of dietary interventions based on the identified 42 RCTs and 23 systematic reviews.
• Training NLP models to extract intervention-outcome relationships from clinical literature based on the review's structured findings.
• Identifying research gaps for future clinical trials based on the review's conclusions about heterogeneous evidence for anxiety.
• Analyzing trends in nutritional psychiatry research methodologies based on the described screening and data extraction procedures.

Strengths

• Includes a substantial evidence base of 42 randomized controlled trials.
• Synthesizes findings from 23 separate systematic evidence syntheses.
• Follows a standardized, duplicate review process for article screening and data extraction.
• Released under a permissive CC-BY-4.0 license.

Limitations

• The dataset is a single 120.6 KB PDF document, representing a limited scope of raw data.
• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying data (e.g., individual trial results) are not provided in a structured, machine-readable format.
