Background :

Recently, the Nordic diet has gained interest, and a healthy Nordic food index has been developed, which has been found inversely related to colorectal cancer among Danish women. This single finding, however, requires replication in other cohorts.

Methods :

We conducted a prospective study in the Women's Lifestyle and Health cohort, including 45,222 women, recruited in 1991-92, and followed up ever since through Swedish registries. Participants were classified according to the Nordic food index, (consisting of wholegrain bread, oatmeal, apples/pears, cabbages, root vegetables and fish/shellfish), and the association between adherence and colorectal cancer was assessed using the Cox Proportional Hazards Models.

Results :

In the fully adjusted models, we found no association, neither with the continuous index score: IRR 1.04 (95% CI 0.95-1.12) per 1 point increment, or in the categorical analyses: IRR 1.09 (95% CI 0.78-1.52) for highest vs. lowest adherers.

Conclusion :

The present study does thus not support a previous finding of an inverse association between a healthy Nordic food index and colorectal cancer. Impact This paper adds new evidence to the field of the Nordic diet in disease prevention.
