Eat Like a Viking

The Nordic Diet continues to grow in popularity, reports Yahoo! Health. It is similar to the Mediterranean diet, except with different foods, such as herring, salmon and lean red meat like bison. Also, instead of olive oil, the Nordic diet uses heart-healthy canola oil. The article cites a study published in the Journal of Internal Medicine showing that participants who followed a Nordic diet for 18-24 weeks lowered their ratio of bad cholesterol to good cholesterol, reducing their risk of cardiovascular disease.
