Background: Studies have indicated that extraweight and obesity induce chronic inflammation, which can lead to other diseases such as cancers. Objective: To evaluate the effects of two weight-lowering and anti-inflammatory agents including cinnamon, and turmeric, on serum levels of interleukin-17 (IL-17) as a pro-inflammatory cytokine. Methods: In this study, 64 rats were designated in eight groups. The control group received normal diet. The other groups were fed with normal diet plus high cinnamon (3 mg/ml), high turmeric (3 mg/ml), high-fructose solution (30%), fructose solution with low (0.15 mg/ml) and high doses (3 mg/ml) of cinnamon and turmeric three times per week. The serum level of IL-17F was measured by enzyme-linked immunosorbent assay (ELISA). Results: High fructose consumption led to an increase in the weight and serum level of IL-17. While, feeding with cinnamon and turmeric caused to decline weight but, surprisingly increased IL-17F levels. Conclusion: Although, some studies have showed that cinnamon and turmeric supplementation decreased IL-17F under the standard diet, in the presence of high fructose diet and extraweight their effects were reversed and caused an increase in serum level of IL-17F.
