- Biomarkers of dietary intake can be important tools in nutrition research. Our aim was to assess whether plasma alkylresorcinol (AR) and beta-carotene concentrations could be used as dietary biomarkers for whole-grain, fruits and vegetables in a healthy Nordic diet (ND). Participants (n = 166), 30-65 y with a body mass index of 27-40 kg/m(2) and two more features of metabolic syndrome (International Diabetes Federation definition, slightly modified), were recruited through six centers in the Nordic countries and randomly assigned to an ND or control diet for 18 or 24 wk, depending on study center. Plasma AR and beta-carotene were analyzed and nutrient intake calculated from 4-d food records. Median fiber intake increased in the ND group from 2.5 g/MJ at baseline to 4.1 g/MJ (P < 0.001) at end point (week 18 or 24), and median (IQR) fasting plasma total AR concentration increased from 73 (88) to 106 (108) nmol/L, or 45%, from baseline to end point (P < 0.001). The AR concentration was significantly higher in the ND group (P < 0.001) than in the control group at end point. beta-Carotene intake tended to increase in the ND group (P = 0.07), but the plasma beta-carotene concentration did not change significantly throughout the study and did not differ between the groups at follow-up. In conclusion, an ND resulted in higher dietary fiber intake and increased plasma total AR concentration compared with the control diet, showing that the total AR concentration might be a valid biomarker for an ND in which whole-grain wheat and rye are important components. No significant difference in plasma beta-carotene concentrations was observed between the ND and control groups, suggesting that beta-carotene may not be a sensitive enough biomarker of the ND.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Det är både tekniskt möjligt och ekonomiskt genomförbart att ställa om till ett CO 2-snålt samhälle2050. Men för att nå en sådan målsättning måste ett antal utmaningar och hinder övervinnas, vilketkan kräva både politisk styrning och institutionell förändring.Denna rapport fokuserar specifikt på samspelet mellan utvecklingen av godstransporter, logistik ochCO 2-utsläpp. Godstransporterna, som styrs och kontrolleras av varuägande företag och aktörer påtransportmarknaden, står för 10-16 % av Sveriges totala CO 2-utsläpp. Trenden för CO 2-utsläpp frångodstransporter är dessutom ökande. Enligt prognoser gjorda på traditionell basis förväntasgodstransporterna fortsätta stiga i takt med BNP så att de blir dubbelt så omfattande 2050. En sådanutveckling står i stark kontrast till de klimatpolitiska mål som Sverige och EU fastslagit som kräverdramatiska minskningar av utsläppen. Den svenska målsättningen för 2030 innebär att CO 2-utsläppenska minska till 20 % av nivån 1990. Det svenska slutmålet för år 2050 innebär nästan en fullständigreduktion av utsläpp av växthusgaser, ett mål som ser svårnått ut med utgångspunkt i prognoserna.

- Background Different healthy food patterns may modify cardiometabolic risk. We investigated the effects of an isocaloric healthy Nordic diet on insulin sensitivity, lipid profile, blood pressure and inflammatory markers in people with metabolic syndrome. Methods We conducted a randomized dietary study lasting for 18-24weeks in individuals with features of metabolic syndrome (mean age 55years, BMI 31.6kgm-2, 67% women). Altogether 309 individuals were screened, 200 started the intervention after 4-week run-in period, and 96 (proportion of dropouts 7.9%) and 70 individuals (dropouts 27%) completed the study, in the Healthy diet and Control diet groups, respectively. Healthy diet included whole-grain products, berries, fruits and vegetables, rapeseed oil, three fish meals per week and low-fat dairy products. An average Nordic diet served as a Control diet. Compliance was monitored by repeated 4-day food diaries and fatty acid composition of serum phospholipids. Results Body weight remained stable, and no significant changes were observed in insulin sensitivity or blood pressure. Significant changes between the groups were found in non-HDL cholesterol (-0.18, mmolL-1 95% CI -0.35; -0.01, P=0.04), LDL to HDL cholesterol (-0.15, -0.28; -0.00, P=0.046) and apolipoprotein B to apolipoprotein A1 ratios (-0.04, -0.07; -0.00, P=0.025) favouring the Healthy diet. IL-1 Ra increased during the Control diet (difference -84, -133; -37ngL-1, P= 0.00053). Intakes of saturated fats (E%, beta estimate 4.28, 0.02; 8.53, P=0.049) and magnesium (mg, -0.23, -0.41; -0.05, P=0.012) were associated with IL-1 Ra. Conclusions Healthy Nordic diet improved lipid profile and had a beneficial effect on low-grade inflammation.
