Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In order to reduce cardiovascular risk, current European guidelines recommend a diet low on saturated fatty acid through replacement with polyunsaturated fatty acids (PUFA). Polyunsaturated fatty acids can be classified into omega-3 and omega-6. However the results from recent meta-analyses investigating coronary risk outcomes did not clearly support a low intake of saturated fatty acids and a high intake of omega-3 or omega-6. The aim of this study is to investigate the short term effects of a high intake of PUFAs on microvascular function, lipids, inflammation and other cardiovascular risk factors in inactive patients with increased waistline.

Study Groups

Omega-3 fatty acid

Omega-3 fatty acids for 8 weeks, dosage are 3 and 4 g/day for women and men, respectively.

Group Type EXPERIMENTAL

Omega-3 Fatty Acid

Intervention Type DIETARY_SUPPLEMENT

Experimental: Omega-3 fatty acid In the intervention period the participants will receive a daily supplement of omega-3 fatty acids for 8 weeks, where the dosage are 3 and 4 g/day for women and men, respectively. The omega-3 supplement is a hydrolyzed and reesterified TAG fish oil, containing 33 area percent eicosapentaenoic acid and 22 area percent docosahexaenoic acid.

Omega-6 fatty acid

Omega-6 fatty acids for 8 weeks, dosage are 20 and 27 g/day for women and men, respectively.

Group Type EXPERIMENTAL

Omega-6 Fatty Acid

Intervention Type DIETARY_SUPPLEMENT

Experimental: Omega-6 fatty acid In the intervention period the participants will receive a daily supplement of omega-6 fatty acid for 8 weeks, where the dosage are 20 and 27 g/day for women and men, respectively. The omega-6 supplement is a high-quality organic, cold pressed and filtered safflower oil, containing 68-83% linoleic acid, 5-15% saturated fatty acid, 8-21% oleic acid, 0,0-0,5% ALA and maximum 2% other fatty acids.
