Cosinor modelling of seasonal variation in 25-hydroxyvitamin D concentrations in cardiovascular patients in Norway
Degerud, Eirik Magnus Meek; Hoff, Rune; Nygård, Ottar; Strand, Elin; Nilsen, Dennis W. T.; Nordrehaug, Jan Erik; Midttun, Øivind; Ueland, Per Magne; De Vogel, Stefan; Dierkes, Jutta (Peer reviewed; Journal article, 2016)Background/Objectives: Seasonal variation may reduce the validity of 25-hydroxyvitamin D (25OHD) as a biomarker of vitamin D status. Here we aimed to identify potential determinants of seasonal variation in 25OHD concentrations ... -
A diet containing cod backbone proteins attenuated the development of mesangial sclerosis and tubular dysfunction in male obese BTBR ob/ob mice

The primary aim of the present study was to investigate if a diet containing fish ... -
Efect of high intake of cod or salmon on serum total neopterin concentration: a randomised clinical trial
Helland, Anita; Bratlie, Marianne; Hagen, Ingrid V.; Midttun, Øivind; Sveier, Harald; Mellgren, Gunnar; Ueland, Per Magne; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2021)Purpose Primarily, to investigate the effect of high intake of cod (lean fish) or salmon (fatty fish) on serum concentration of total neopterin, a marker of cellular immune activation that is associated with cardiovascular ... -
Effect of cod residual protein supplementation on markers of glucose regulation in lean adults: A randomized double-blind study
Vildmyren, Iselin; Halstensen, Alfred; McCann, Adrian; Midttun, Øivind; Ueland, Per Magne; Oterhals, Åge; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2020)Large quantities of protein-rich cod residuals, which are currently discarded, could be utilized for human consumption. Although fish fillet intake is related to beneficial health effects, little is known about the potential ... -
Effects of high intake of cod or salmon on gut microbiota profile, faecal output and serum concentrations of lipids and bile acids in overweight adults: a randomised clinical trial

Methods Seventy-six adults with overweight/obesity with no ... -
Five salmon dinners per week were not sufficient to prevent the reduction in serum vitamin D in autumn at 60° north latitude: A randomised trial
Bratlie, Marianne; Hagen, Ingrid Valheim; Helland, Anita; Midttun, Øivind; Ulvik, Arve; Rosenlund, Grethe; Sveier, Harald; Mellgren, Gunnar; Ueland, Per Magne; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2020)Low serum concentrations of several vitamins have been linked to increased risk of diseases including insulin resistance and type 2 diabetes (T2D).
