Background:
Cardiovascular diseases are among the main causes of morbidity and mortality in Norway. The objective of this article is to provide an overview of literature that describes the effect of a Nordic diet in line with the authorities’ dietary advice on risk factors for cardiovascular disease.
Method:
Electronic literature searches were undertaken in the PubMed, Cochrane and Embase databases. Randomised, controlled studies that described the Nordic diet and cardiovascular disease were included. A total of 15 articles were included. These are based on four dietary intervention studies conducted in the Nordic countries.
Results:
All of the dietary intervention studies indicated effects on blood lipids. In one of the studies, a Nordic diet caused a 21 % reduction in LDL cholesterol levels. Three of the studies showed that a Nordic diet reduces blood pressure. Results from two of the studies showed that it also improved glucose and insulin sensitivity, but after adjustment for weight loss, this effect disappeared. Three of the studies showed that a Nordic diet may positively affect inflammation.
Interpretation:
A diet based on the authorities’ dietary recommendation and consisting of Nordic ingredients improves the risk profile in those who are predisposed to developing cardiovascular disease.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
