Apple consumption reduces markers of postprandial inflammation following a high fat meal in overweight and obese adults: A randomized, crossover trial

) of lipopolysaccharide (LPS) to measure secreted cytokines. Apples modulated postprandial plasma IFN-γ and reduced its peak concentration (-12.8%), and increased both 4 h (14.4%) and peak (10.5%) TAC (P < 0.05). In unstimulated and LPS-stimulated PBMC, apples reduced secreted IL-6 (-49.3% and -17.1%) and TNF-α (-43.3% and -14.7%) and increased IL-4 (93.1% and 15.8%) in both the unstimulated and LPS-stimulated conditions, as well as decreased GM-CSF (-26.0%) and IL-17 (-47.9%) in unstimulated PBMC and G-CSF (-19.8%) in LPS-stimulated PBMC (P < 0.05). These data suggest acute whole Gala apple consumption may be an effective dietary strategy to mitigate high fat meal-induced postprandial inflammation that exacerbates CVD risk in overweight and obesity.
