Brief Summary:
The aim of this study is to investigate the effects of acute and short-term intervention with fish oil on inflammatory markers in overweight subjects.

Condition or disease Intervention/treatment Phase
Overweight Dietary Supplement: fish oil Dietary Supplement: olive oil Not Applicable

Detailed Description:

Being overweight is associated with metabolic syndrome, cardiovascular disease, and diabetes mellitus (type 2). Adipose tissue can be regarded as an active organ, which produces an array of inflammatory mediators. This creates a state of chronic low-grade inflammation. Inflammation has been proven to be a key element in the development of atherosclerotic plaques.

The marine n-3 polyunsaturated fatty acids (PUFAs) have beneficial effects on cardiovascular disease. These effects are partly attributed to the anti-inflammatory effect of the n-3 PUFAs.

Previous studies have shown an anti-inflammatory effect of n-3 PUFAs in overweight subjects, but the studies have been conducted with a high daily dose of n-3 PUFA. We want to examine the effect of a lower dose of 1 g n-3 PUFA/day (the dose recommended by the Danish Heart Foundation).

The study is randomized, placebo-controlled and double blinded. Fifty subjects aged 30 - 75 years (postmenopausal women; waist circumference > 80 cm and men; waist circumference > 94 cm) will be included.

Blood samples and fatty tissue biopsies will be collected at baseline, after 1 day and after 6 weeks.

Arm Intervention/treatment
Experimental: Fish oil Dietary Supplement: fish oil
Capsules. Approximately 1000 mg n-3 PUFA daily. One day + 6 weeks
Placebo Comparator: Olive oil Dietary Supplement: olive oil
Capsules. Approximately 1 g olive oil daily. One day + 6 weeks

Primary Outcome Measures :
  1. To assess the effect of 1 g/day of n-3 polyunsaturated fatty acids on inflammatory markers [ Time Frame: After 1 day and after 6 weeks intervention ]

Secondary Outcome Measures :
  1. To assess effect of 1 g n-3 polyunsaturated fatty acids (daily dose) on the fatty acid profile of plasma, leucocytes and adipose tissue. [ Time Frame: After 1 day and 6 after weeks of intervention ]
  2. To assess the effect of 1g n-3 polyunsaturated fatty acids (daily dose) on the gene expression profile (mRNA) - especially genes involved in encoding the inflammatory response. [ Time Frame: After 1 day and 6 after weeks of intervention ]
