Anthocyanins are the pigments that give berries, cherries, and red cabbage their color. They are also among the most studied plant compounds for their effect on inflammation, and the mechanisms are more specific than a general “antioxidant” label.
The central mechanism involves NF-κB, a protein that acts as a master switch for inflammatory genes. In the inactive state, NF-κB is held in the cytoplasm by an inhibitor. When that inhibitor is degraded, NF-κB enters the nucleus and turns on inflammatory molecules. A 2024 review in China Food Additives summarizes the evidence: anthocyanins inhibit MAPK expression and NF-κB pathway activation. A 2026 review in Food Research International adds precision, describing how anthocyanins suppress stress-responsive p-p38 and p-JNK, which in turn prevents NF-κB-driven cytokine production.
The consequence is measurable in human trials. A meta-analysis of 32 randomized controlled trials found that dietary anthocyanins significantly reduced C-reactive protein, interleukin-6, tumor necrosis factor-alpha, and two vascular adhesion molecules linked to endothelial inflammation. Doses above 300 mg per day produced larger reductions. A 2025 trial on blackcurrant anthocyanins found improved endothelial function after a high-fat meal, consistent with the vascular effects seen in the meta-analysis.
What this does not mean is that a bowl of berries will “cure” inflammation. The evidence supports anthocyanin-rich whole foods as part of a varied diet that may help maintain a balanced inflammatory response over time.
