What was done
A review of 57 human interventional studies evaluating acute postprandial inflammation following a high-fat meal. The authors evaluated the reported responses of circulating inflammatory markers and compared these patterns to human models of experimental low-grade endotoxaemia.
What was found
The abstract reports no numerical data, pooled effect sizes, or confidence intervals. Circulating plasma-borne markers, such as cytokines and soluble adhesion molecules, were not consistently elevated after a high-fat meal. In contrast, pro-inflammatory leukocyte surface markers, mRNA, and proteins were elevated in nearly all studies measuring them. These leukocyte responses showed kinetics similar to intravenous low-dose endotoxin administration, were positively associated with the likelihood of bacterial contamination in test meals, and were attenuated by co-ingestion of anti-inflammatory phytochemicals.
Why it matters
This review clarifies conflicting findings in postprandial research by demonstrating that acute high-fat meal responses manifest primarily through leukocyte activation rather than circulating plasma cytokines.
Limits
The abstract provides no quantitative data or statistical comparisons. It lacks details on the systematic nature of the search, inclusion criteria, risk of bias assessments, study populations, caloric content, or specific fat compositions of the test meals.
