Micronutrients & recovery
High dietary fiber intake is associated with reduced mortality from infectious and respiratory diseases, likely mediated by gut microbiota fermentation into anti-inflammatory short-chain fatty acids.
Aim to increase your daily dietary fiber intake by 10 grams. This simple change is associated with a significant reduction in mortality from infectious and respiratory diseases. Focus on plant-based sources like vegetables, fruits, nuts, seeds, and whole grains.
GoodSupportsHIGH confidence
Consumption of dietary fiber correlated with lowered mortality from infectious and respiratory diseases. Per 10 g/d increase in dietary fiber, the multivariate RRs for infectious and respiratory diseases were 0.66... and 0.82... in men and women, respectively.
Why this rating
Based on large prospective human cohort study (n > 380,000) and animal studies.

- Vitamin D supplementation reduces the incidence of respiratory tract infections, with protective effects being more pronounced with daily dosing compared to bolus doses.Good
- Adequate protein intake (≥0.8 g/kg body weight) is essential for optimal antibody production and immune cell function, whereas very low protein status increases infection risk and mortality.Moderate
- Omega-3 fatty acid supplementation reduces pro-inflammatory cytokines (e.g., IL-6) and may improve outcomes in viral infections, though excessive inflammation reduction during active infection could potentially be detrimental.Moderate
