In our previous study, it was established that depending
on the type of food and the form of the fish oil, the
threshold level of food fortification usually ranged from 1
up to 60 g kg1 (Kolanowski et al., 1999). In the present
study, it was shown that certain selected dairy products
were suitable for fortification with fish oil and that these
might provide significant amounts of omega-3 LC PUFA
to the diet (Fig. 1). It is supposed that a daily portion (say
30 g) of spreadable fresh cheeses, butter or processed
cheeses evaluated in this study and fortified with fish oil at
the estimated levels 20, 30 and 40 g kg1, respectively,
might provide approximately 180, 270 and 360 mg of
omega-3 LC PUFA (Fig. 1). This could significantly
elevate the average intake of omega-3 LC PUFA.
