Beneficial effect on serum cholesterol levels, but not glycaemic regulation, after replacing SFA with PUFA for three days: a randomised crossover trial
Gaundal, Line; Myhrstad, Mari; Leder, Lena; Byfuglien, Marte Gjeitung; Gjøvaag, Terje; Rud, Ida; Retterstøl, Kjetil; Holven, Kirsten Bjørklund; Ulven, Stine Marie; Telle-Hansen, Vibeke (Peer reviewed; Journal article, 2020)Replacing intake of SFA with PUFA reduces serum cholesterol levels and CVD risk. The effect on glycaemic regulation is, however, less clear. The main objective of the present study was to investigate the short-term effect ... -
Bioavailability of n-3 fatty acids from n-3 enriched foods and fish oil with different oxidative quality in healthy humans – a randomized single meal cross-over study
Ottestad, Inger; Nordvi, Berit; Vogt, Kjell Gjermund; Holck, Marianne; Halvorsen, Bente; Brønner, Kirsti Wettre; Retterstøl, Kjetil; Holven, Kirsten Bjørklund; Nilsson, Astrid; Ulven, Stine Marie (Journal article, 2016)Regular consumption of long-chain n-3 fatty acids (LC n-3 FA) reduces postprandial triacylglycerolaemia. Functional foods and supplements are alternative sources of LC n-3 FA; however, emulsification technologies, food ... -
Gut microbiota is associated with dietary intake and metabolic markers in healthy individuals
Gaundal, Line; Myhrstad, Mari; Rud, Ida; Gjøvaag, Terje; Byfuglien, Marte G.; Retterstøl, Kjetil; Holven, Kirsten Bjørklund; Ulven, Stine Marie; Telle-Hansen, Vibeke (Peer reviewed; Journal article, 2022)Background: Metabolic diseases have been related to gut microbiota, and new knowledge indicates that diet impacts host metabolism through the gut microbiota. Identifying specific gut bacteria associated with both diet and ... -
Polyphenol-rich juices reduce blood pressure measures in a randomised controlled trial in high normal and hypertensive volunteers
Tjelle, Torunn Elisabeth; Holtung, Linda; Bøhn, Siv Kjølsrud; Aaby, Kjersti; Thoresen, Magne; Wiik, Siv Åshild; Paur, Ingvild; Karlsen, Anette Solli; Retterstøl, Kjetil; Iversen, Per Ole; Blomhoff, Rune (Peer reviewed; Journal article, 2015)Intake of fruits and berries may lower blood pressure (BP), most probably due to the high content of polyphenols. In the present study, we tested whether consumption of two polyphenol-rich juices could lower BP. In a ... -
Replacing saturated fatty acids with polyunsaturated fatty acids increases the abundance of Lachnospiraceae and is associated with reduced total cholesterol levels-a randomized controlled trial in healthy individuals
Telle-Hansen, Vibeke; Gaundal, Line; Bastani, Nasser Ezzatkhah; Rud, Ida; Byfuglien, Marte G.; Gjøvaag, Terje; Retterstøl, Kjetil; Holven, Kirsten Bjørklund; Ulven, Stine Marie; Myhrstad, Mari (Peer reviewed; Journal article, 2022)Improving dietary fat quality strongly affects serum cholesterol levels and hence the risk of cardiovascular diseases (CVDs). Recent studies have identified dietary fat as a potential modulator of the gut microbiota, a ...
