Abstract
- The Inuit undergo substantial changes in their lifestyle, but few data exist on how these changes occur in biomarkers, such as polyunsaturated fatty acids (PUFAs). Here, we report data from a cross-sectional survey conducted in 2004 among 861 representative Nunavik Inuit adults, in whom FAs were measured in red blood cells (RBCs). FAs were also measured in plasma phospholipids (n=452) to assess temporal trend by comparing plasma PUFAs measured in 1992. Food intakes were estimated using a validated food frequency questionnaire. In 2004, marine food intake was 84±4g/d (±SEM). Adjusted-mean of RBC omega-3 was significantly higher, and omega-6 lower, in older age groups (Ptrend<0.001). In 2004, plasma omega-3 was 25% lower, while omega-6 was 9% higher, compared to 1992. Our study revealed that Nunavik Inuit adults still have high RBC omega-3, but show signs of nutritional transition - as indicated by lower omega-3 and higher trans-fats in RBCs of young compared to older.<br /> (Copyright © 2014 Elsevier Ltd.
