 The study consisted of two investigation periods of 12 weeks, with an eight-week washout period in between. 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 with high amounts of eicosapentaenoic acid EPA, docosahexaenoic acid DHA, and alpha linoleic acid ALA. The daily dose of n-3 FA amounted to 2.4 g, consisting of 1.1 g ALA, 0.7 g EPA, 0.1 g DPA, and 0.4 g DHA. The placebo products were commercial dairy products with comparable fat contents.
