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

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

|
Changes in lipid profile
Zeitfenster: Measured at baseline and after 8 weeks
|
High-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol and triglycerides (TG) will be measured in plasma/serum (mmol/L).
|
Measured at baseline and after 8 weeks
|
|
Changes in particle concentrations of lipoproteins of different sizes
Zeitfenster: Measured at baseline and week 8
|
Particle concentration (nmol/L) of lipoprotein of different sizes will be calculated from the measured amplitude of their spectroscopically lipid methyl group NMR signals.
|
Measured at baseline and week 8
|
|
Changes in lipoprotein particle sizes
Zeitfenster: Measured at baseline and week 8
|
Lipoprotein particle size (nm) analysis will be performed by proton nuclear magnetic resonance (NMR) spectroscopy.
The size will be derived from the sum of diameter of each subclass multiplied by its relative mass percentage based on its methyl NMR signal.
