  In healthy adults, what is the effect of the amount of saturated fat intake on c-reactive protein (CRP)?

  • Conclusion

    In healthy adults, replacement of saturated fatty acids with monounsaturated fatty acids significantly decreases CRP levels. Replacement with oleic acid, in comparison to supplementation with stearic, lauric, myristic and palmitic fatty acids, significantly reduced CRP levels, however, effect size was small [MD, -0.010 (95% CI, -0.019 to -0.002)].

  In healthy adults, what is the effect of amount of saturated fat intake on interleukin 6 (IL-6)?

  • Conclusion

    In healthy adults, the effect of a reduced amount of saturated fat intake on interleukin 6 (IL-6) concentration is unclear. No statistically significant difference was found in pooled analysis on IL-6 concentration when saturated fatty acids were replaced with monounsaturated fatty acids after five weeks, and heterogeneity amongst studies was moderately high.
