Both diet-induced regulation and dietary content of one-carbon metabolites can influence circulating concentrations ... -
The Association of Meat Intake With All-Cause Mortality and Acute Myocardial Infarction Is Age-Dependent in Patients With Stable Angina Pectoris
Matre, Åslaug Oddsdatter; Van Parys, Anthea; Olsen, Thomas; Haugsgjerd, Teresa Risan; Baravelli, Carl Michael; Nygård, Ottar; Dierkes, Jutta; Lysne, Vegard (Journal article; Peer reviewed, 2021)Background: Red and processed meat intake have been associated with increased risk of morbidity and mortality, and a restricted intake is encouraged in patients with cardiovascular disease. However, evidence on the association ... -
Creatinine, total cysteine and uric acid are associated with serum retinol in patients with cardiovascular disease
Olsen, Thomas; Vinknes, Kathrine; Blomhoff, Rune; Lysne, Vegard; Midttun, Øivind; Dhar, Indu; Ueland, Per Magne; Svingen, Gard Frodahl Tveitevåg; Pedersen, Eva Ringdal; Drevon, Christian A; Refsum, Helga; Nygård, Ottar (Peer reviewed; Journal article, 2019-09-09)Purpose: We hypothesized that biomarkers and dietary factors related to cardiovascular disease risk were associated with serum retinol and evaluated these potential associations in patients with suspected coronary artery ... -
Food Sources Contributing to Intake of Choline and Individual Choline Forms in a Norwegian Cohort of Patients With Stable Angina Pectoris
Van Parys, Anthea; Karlsson, Therese; Vinknes, Kathrine; Olsen, Thomas; Øyen, Jannike; Dierkes, Jutta; Nygård, Ottar Kjell; Lysne, Vegard (Journal article; Peer reviewed, 2021)Background: Choline is an essential nutrient involved in a wide range of physiological functions. It occurs in water- and lipid-soluble forms in the body and diet. Foods with a known high choline content are eggs, beef, ... -
Lipid parameters and vitamin A modify cardiovascular risk prediction by plasma neopterin
Dhar, Indu; Siddique, Sumia; Pedersen, Eva Kristine Ringdal; Svingen, Gard FT; Lysne, Vegard; Olsen, Thomas; Nilsen, Dennis W.T.; Nordrehaug, Jan Erik; Midttun, Øivind; Ueland, Per Magne; Tell, Grethe S; Nygård, Ottar (Journal article; Peer reviewed, 2020)Objectives Oxidised cholesterol metabolites are linked to increased production of the active vitamin A (Vit-A) form and monocyte/macrophage activation, which may be reflected by neopterin, a marker of both interferon-γ–mediated ... -
