 The placebo-controlled, randomized double-blind cross-over study consisted of two investigation periods of 15 weeks, with a ten-week washout period in between. After the washout period the intervention was crossed between the groups and the respective products were consumed for another 15 weeks. Patients received about 40 g fat daily 200 g yoghurt with 3.8 fat, 30 g cheese with about 50 fat in the dry matter, and 20-30 g butter. The milk fat was partially exchanged by special oils fish oil, rapeseed oil with high amounts of eicosapentaenoic acid EPA, docosahexaenoic acid DHA, and alpha linolenic acid ALA. The daily dose of n-3 FA amounted to 3.3 g, consisting of 1.5 g EPA, 1.2 g DHA, 0.2 g DPA, and 0.2 g ALA.
