Conclusion The Nordic dietary pattern  improves blood pressure and also some of blood lipid markers and it should be considered as a healthy dietary pattern
Background and aims 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 r and omized controlled trials ( RCTs ) , this study aim ed 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 .
Diet-induced changes in iron and n-3 fatty acid status and associations with cognitive performance in 8-11-year-old Danish children: secondary analyses of the Optimal Well-Being, Development and Health for Danish Children through a Healthy New Nordic Diet School Meal Study.
Fe and n-3 long-chain PUFA ( n-3 LCPUFA ) have both been associated with cognition , but evidence remains inconclusive in well-nourished school-aged children . In the Optimal Well-Being , Development and Health for Danish Children through a Healthy New Nordic Diet ( OPUS ) School Meal Study , the 3-month intervention increased reading performance , inattention , impulsivity and dietary intake of fish and Fe . This study investigated whether the intervention influenced n-3 LCPUFA and Fe status and , if so , explored how these changes correlated with the changes in cognitive performance . The study was a cluster-r and omised cross-over trial comparing school meals with packed lunch ( control ) . At baseline and after each treatment , we measured serum ferritin , whole-blood n-3 LCPUFA and Hb , and performance in reading , mathematics and d2-test of attention . Data were analysed using mixed models ( n 726 ) and principal component analysis of test performances ( n 644 ) , which showed two main patterns : ' school performance ' and ' reading comprehension ' . The latter indicated that children with good reading comprehension were also more inattentive and impulsive ( i.e. higher d2-test error% ) . The intervention improved ' school performance ' ( P=0·015 ) , ' reading comprehension ' ( P=0·043 ) and EPA+DHA status 0·21 ( 95 % CI 0·15 , 0·27 ) w/w % ( P<0·001 ) , but it did not affect serum ferritin or Hb . At baseline , having small Fe stores was associated with poorer ' school performance ' in girls , but with better ' reading comprehension ' in both boys and girls . Both baseline EPA+DHA status and the intervention-induced increase in EPA+DHA status was positively associated with ' school performance ' , suggesting that n-3 LCPUFA could potentially explain approximately 20 % of the intervention effect . These exploratory associations indicate that increased fish intake might explain some of the increase in reading performance and inattention in the study
