The claimed functional foods and specialized foods each contain a
physiologically compatible phospholipid-containing stable matrix
consisting of a supporting material and a bioactive component, the
phospholipid component being in particular phosphatidyl serine,
phosphatidyl choline and similar compounds, lyso variants and/or
derivatives thereof. Liquid, solid and semiliquid forms of administration
are preferred as the functional foods; food for tube feeding is regarded
as preferred among the specialized foods. The matrix used for this should
preferably have liquid contents and in particular have a diameter between
0.1 .mu.m and 5.0 mm. It is also preferred when the matrix develops a
delayed release after its ingestion with the respective foods which
should preferably take place in the gastro-intestinal tract.
