This dietary pattern did not significantly affect 2-h post-pr and ial blood glucose and Matsuda index .
Conclusions Adherence to the ND might improve serum insulin and HOMA-IR levels ; however , this effect was not confirmed for other markers of blood glucose control .
Aims Investigations on the possible effect of the Nordic diet ( ND ) on the glycemic control and the risk of diabetes have led to inconsistent results .
The present study tried to determine the effect of the ND on the markers of blood glucose control using a systematic review and meta- analysis of r and omized controlled clinical trials ( RCTs ) .
Plate waste and intake of school lunch based on the new Nordic diet and on packed lunches: a randomised controlled trial in 8- to 11-year-old Danish children
The aim of the present study was to compare total food intake , total and relative edible plate waste and self-reported food likings between school lunch based on the new Nordic diet ( NND ) and packed lunch from home . In two 3-month periods in a cluster-r and omised controlled unblinded cross-over study 3rd- and 4th- grade children ( n 187 ) from two municipal schools received lunch meals based on NND principles and their usual packed lunch ( control ) .  Food intake and plate waste ( n 1558 ) were calculated after weighing lunch plates before and after the meal for five consecutive days and self-reported likings ( n 905 ) assessed by a web-based question naire . Average food intake was 6 % higher for the NND period compared with the packed lunch period . The quantity of NND intake varied with the menu ( P < 0·0001 ) and was positively associated with self-reported likings . The edible plate waste was 88 ( sd 80 ) g for the NND period and 43 ( sd 60 ) g for the packed lunch period whereas the relative edible plate waste was no different between periods for meals having waste ( n 1050 ) . Edible plate waste differed between menus ( P < 0·0001 ) , with more waste on soup days ( 36 % ) and vegetarian days ( 23 % ) compared with the packed lunch period . Self-reported likings were negatively associated with percentage plate waste ( P < 0·0001 ) . The study suggests that portion sizes need to be considered in new school meal programmes . New strategies with focus on reduction of plate waste , children 's likings and nutritious school meals are crucial from both a nutritional , economic and environmental point of view
