Quite separately, knowledge of the EFA grew; the physiologists described a variety of deficiency symptoms associ- ated with a fat deficiency, including testicular atrophy, and in- creased permeability in the skin and cell membranes. Both linoleic BACKGROUND TO ESSENTIAL FATTY and a-linolenic acids supported growth in fat-deficient rats and were considered to possess EFA activity. However, a-linolenic acid ACIDS AND THEIR PROSTANOID appeared to have functions similar to linoleic acid but was less DERIVATIVES active; hence linoleic acid attracted far more attention from research workers. Any doubt that the EFA were required in the human was dispelled when Hansen et at. (1963) described severe MICHAEL A CRAWFORD PhD skin symptoms in infants who were fed a milk diet in which the EFAs were virtually absent (see Soderhjelm et al. 1970). Addition Nuffield Laboratories of Comparative Medicine of EFA corrected the skin symptoms.
