Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="mnfr2301-sec-0010" sec-type="section"> <title>Scope</title> <p>Obesity is associated with hyperlipidemia, hepatic steatosis, and low‐grade inflammation. Studies have shown that MUFA as well as PUFA have beneficial effects on blood lipids and the inflammatory state.</p> </sec> <sec id="mnfr2301-sec-0020" sec-type="section"> <title>Methods and results</title> <p>This study investigates the effects of a daily supplementation of either 50 g of rapeseed/canola (RA) or olive (OL) oil over 4 wk on serum lipids, serum liver enzymes, and inflammatory gene expression in subcutaneous (s. c.) adipose tissue in obese men. Consuming RA resulted in increased serum <italic>n</italic>‐3 fatty acids and a reduction in total cholesterol, LDL cholesterol, and serum aspartate aminotransferase compared to OL. In s. c. adipose tissue, gene expression of the pro‐inflammatory cytokine IL6 was reduced in RA compared to OL. However, after 4 h after a test meal, containing the appropriate oil, white bread, and 400 mL of liquid diet drink (835 kcal in total), gene expression of IL6, IL1B, and EMR1 (egf‐like module containing Mucin‐like hormone receptor‐like 1) was increased in RA and of monocyte chemoattractant protein‐1 (CCL2) in both RA and OL.</p> </sec> <sec id="mnfr2301-sec-0030" sec-type="section"> <title>Conclusion</title> <p>This demonstrates that consuming RA for 4 wk improves serum lipids, liver enzymes, and basal inflammation in s. c. adipose tissue, but it mediates an acute pro‐inflammatory response in adipose tissue upon consuming a meal.</p> </sec> </abstract>
