HealthDay News — Based on a study published in Obesity Reviews on July 13, 2016, diets primarily based on plant products have been associated with improvements in obesity-related inflammatory biomarker profiles, including a decrease in C-reactive proteins and interleukin-6 levels.
Fabian Eichelmann, from the German Institute of Human Nutrition Potsdam-Rebrücke, and colleagues conducted a systematic review and meta-analysis of intervention trials to examine the effect of plant-based diets on obesity-related inflammatory biomarker profiles. 29 of 2,583 publications, with 2,689 participants, met the inclusion criteria.
The researchers found that consumption of plant-based diets correlated with a decrease in the mean concentrations of C-reactive protein (effect size, −0.55 mg/L), interleukin-6 (effect size, −0.25 ng/L), and soluble intercellular adhesion molecule 1 (effect size, −25.07 ng/mL). For tumor necrosis factor-α, resistin, adiponectin, and leptin there were no substantial effects.
“Plant-based diets are associated with an improvement in obesity-related inflammatory profiles and could provide means for therapy and prevention of chronic disease risk,” the authors write.
