The effect of healthy Nordic diet on cardio-metabolic markers: a systematic review and meta-analysis of randomized controlled clinical trials.

The Nordic diet (ND), is supposed to be associated with a reduced cardiovascular risk; however, clinical trials have led to inconsistent results regarding the effect of this diet on cardio-metabolic markers. Using systematic review and meta-analysis of randomized controlled trials (RCTs), this study aimed to investigate the effect of the ND on circulating levels of total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol, and triglyceride (TG), as well as blood pressure in human adults.
