The summary will be limited to the areas that should be intensively investigated. The first is: determination of fatty acid profiles using modern methods on a world wide basis. We have no more than five or six papers in which my criterion was applied, one from Canada and the remainder from Europe with some data from Africa. Obviously, milk cannot be used as the gold standard on this meager data base. The second area is analysis of TG structure. These analyses are difficult, but structure is one of the factors controlling digestion. Data on the effects of maternal diet on structure would be useful. The third area is the role of primary or derived milk lipids as microbicidal agents. The fourth area is examination of globule parameters, i.e. number, size, volume, surface, and how they are affected by diet. There are many others which may interest the reader.
