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 .
Effects of school meals with weekly fish servings on vitamin D status in Danish children: secondary outcomes from the OPUS (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet) School Meal Study
Children 's vitamin D intake and status can be optimised to meet recommendations . We investigated if nutritionally balanced school meals with weekly fish servings affected serum 25-hydroxyvitamin D ( 25(OH)D ) and markers related to bone in 8- to 11-year-old Danish children . We conducted an explorative secondary outcome analysis on data from 784 children from the OPUS School Meal Study , a cluster-r and omised cross-over trial where children received school meals for 3 months and habitual lunch for 3 months . At baseline , and at the end of each dietary period , 25(OH)D , parathyroid hormone ( PTH ) , osteocalcin ( OC ) , insulin-like growth factor-1 ( IGF-1 ) , bone mineral content ( BMC ) , bone area ( BA ) , bone mineral density ( BMD ) , dietary intake and physical activity were assessed . School meals increased vitamin D intake by 0·9 ( 95 % CI 0·7 , 1·1 ) μg/d . No consistent effects were found on 25(OH)D , BMC , BA , BMD , IGF-1 or OC . However , season-modified effects were observed with 25(OH)D , i.e. children completing the school meal period in January/February had higher 25(OH)D status ( 5·5 ( 95 % CI 1·8 , 9·2 ) nmol/l ; P = 0·004 ) than children completing the control period in these months . A similar tendency was indicated in November/December ( 4·1 ( 95 % CI –0·12 , 8·3 ) nmol/l ; P = 0·057 ) . However , the effect was opposite in March/April ( –4·0 ( 95 % CI –7·0 , –0·9 ) nmol/l ; P = 0·010 ) , and no difference was found in May/June ( P = 0·214 ) . Unexpectedly , the school meals slightly increased PTH ( 0·18 ( 95 % CI 0·07 , 0·29 ) pmol/l ) compared with habitual lunch . Small increases in dietary vitamin D might hold potential to mitigate the winter nadir in Danish children 's 25(OH)D status while higher increases appear necessary to affect status throughout the year . More trials on effects of vitamin D intake from natural foods are needed
