Systematic Review of Health and Food Literacy Associations with Diet

17 studies from a systematic review of 1,491 records synthesize evidence on the relationship between health literacy, food literacy, and dietary choices. The review was conducted by Eva-Maria Steinke following PRISMA 2020 protocol and published in 2026. It analyzes associations between literacy constructs and dietary behavior, nutritional knowledge, and food-related decision-making.

Use Cases

• Analyze the correlation between health literacy scores and dietary behavior metrics across the 17 included studies.
• Compare measurement tools for food literacy and nutritional literacy used in the synthesized research.
• Identify gaps in the multidimensional assessment of food literacy based on the review's findings on study focus.
• Assess the influence of socioeconomic context on the relationship between literacy constructs and diet quality as discussed in the conclusions.

Strengths

• Synthesizes evidence from 17 studies identified through a systematic search of 1,491 records.
• Follows the PRISMA 2020 protocol and uses the Academy of Nutrition and Dietetics Quality Criteria Checklist for bias assessment.
• Provides a clear PROSPERO registration identifier (CRD420250652344) for transparency.

Limitations

• Limited to 17 final studies, indicating a narrow evidence base for conclusive findings.
• High heterogeneity in measurement tools for literacy constructs, limiting comparability.
• The dataset is a 28.5 KB summary table, containing no raw study data or participant-level records.
