Abstract

Growing evidence supports the hypothesis that dietary factors may play a role in systemic low-grade chronic inflammation. Summary evidence from randomized controlled trials has shown substantial effects on biomarkers of inflammation following the adoption of plant-based diets (including, but not limited to, the Mediterranean diet), while consistent findings have been reported for higher intakes of whole grains, fruits, and vegetables and positive trends observed for the consumption of legumes, pulses, nuts, and olive oil. Among animal food groups, dairy products have been shown to have the best benefits on biomarkers of inflammation, while red meat and egg have been shown to have neutral effects. The present review provides an overview of the mechanisms underlying the relation between dietary factors and immune system, with a focus on specific macronutrient and non-nutrient phytochemicals (polyphenols) and low-grade inflammation. Substantial differences within each macronutrient group may explain the conflicting results obtained regarding foods high in saturated fats and carbohydrates, underlying the role of specific subtypes of molecules (i.e., short-chain fatty acids or fiber vs. long chain fatty acids or free added sugars) when exploring the relation between diet and inflammation, as well as the importance of the food matrix and the commixture of foods in the context of whole dietary patterns. Dietary polyphenols and oligopeptides have been hypothesized to exert several functions, including the regulation of the inflammatory response and effects on the immune system. Overall, evidence suggests that dietary factors may affect the immune system regardless of obesity-related inflammation.

  • Nutrigenetics and nutrigenomics offer promising conceptual frameworks for understanding how genetic variants affect nutrient response and how diet can modulate gene expression.

    “On the other hand, nutrigenetics and nutrigenomics offer promising conceptual frameworks for understanding how genetic variants affect nutrient response and how diet can modulate gene expression [143,144].”

    From The Seven Methods for the Evaluation of Nutritional Status—ABCDEFG: Narrative Review (2026) · cites this paper as [144]

    Section 8 says genetics plays a pivotal role in inflammatory responses to dietary exposure, supporting the genetic-response part of the claim. Section 2 describes food ingestion activating transcription factors and upregulating pro-inflammatory genes, supporting a diet–gene-expression link. The paper does not discuss nutrigenetics and nutrigenomics together as conceptual frameworks; it names nutrigenetics only in a reference title. (LLM, conf=0.82)

  • Macronutrients and micronutrients can modulate pro-inflammatory and anti-inflammatory cascades, influencing a person's baseline inflammatory status.

    “Evidence indicates that macronutrients and micronutrients can modulate pro-inflammatory and anti-inflammatory cascades, influencing a person’s baseline inflammatory status [19].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
