Abstract
We explored if linoleic acid (LA) and alpha-linolenic acid (ALA) will be efficiently converted to arachidonic acid (AA) and docosahexaenoic acid (DHA) in the adolescent girls (aged 15-18 years, n=145) in Mozambique consuming habitually low fat diet and if low iron and/or zinc status predicts the conversion. Total fat, LA and ALA intakes were 15-19%, 1.2-3.5% and 0.2-0.3% of energy, respectively in three areas. Iron and zinc intake varied between 9.6-12.3mg/day and 3.6-5.0mg/day. Significant negative association of plasma AA was found with plasma LA and ALA and significant positive association with serum ferritin. Plasma DHA associated, negatively with plasma LA and ALA. We showed that in a population with low intakes of LA and ALA, the proportions of phospholipid LA and ALA determines the relative proportions of AA and DHA and low iron status probably attenuates the conversion of LA to AA.
