High unfavorable dietary components (processed meats, red meats, refined grains, high-fat patterns) are associated with increased all-cause mortality but show no significant association with cardiovascular mortality after full adjustment.
Avoiding processed meats, refined grains, and high-fat patterns is important for overall survival, even if it doesn't directly predict heart disease death in this specific population. It contributes to general longevity.

Conversely, elevated unfavorable scores were linked to greater all-cause mortality risk (Q4 vs Q1 HR = 1.58, 95% CI: 1.12–2.24), but showed no significant association with cardiovascular mortality.
Why this rating
Clear statistical association with all-cause mortality in adjusted models.

- Higher scores on the Dietary Index for Gut Microbiota (DI-GM), specifically driven by beneficial components, are associated with significantly reduced all-cause and cardiovascular mortality in individuals with Cardiovascular-Kidney-Metabolic (CKM) syndrome stages 0-3.Good
- The protective effect of beneficial dietary components on all-cause mortality is partially mediated by a reduction in systemic inflammation, as measured by the Systemic Inflammation Index (SII).Good
