Basal Ration

Vegetable oils containing stearidonic acid (SDA, 18 : 4n-3) are considered better precursors of long-chain n-3 PUFA (LC n-3 PUFA) than those with only α-linolenic acid (ALA, 18 : 3n-3). The present study re-examined this premise using treatments where added ALA from linseed oil was matched with ALA plus SDA from echium oil. Lambs (n 6) were abomasally infused with saline (control (C), 25 ml), echium oil low (EL, 25 ml), echium oil high (EH, 50 ml), linseed oil low (LL, 25 ml) or linseed oil high (LH, 50 ml) for 4 weeks. The basal ration used was identical across all treatments. EPA (20 : 5n-3) in meat increased from 6·5 mg in the C lambs to 16·8, 17·7, 13·5 and 11·7 (sem 0·86) mg/100 g muscle in the EL, EH, LL and LH lambs, respectively. For muscle DPA (docosapentaenoic acid; 22 : 5n-3), the corresponding values were 14·3, 22·2, 18·6 18·2 and 19·4 (sem 0·57) mg/100 g muscle. The DHA (22 : 6n-3) content of meat was 5·8 mg/100 g in the C lambs and ranged from 4·53 to 5·46 (sem 0·27) mg/100 g muscle in the oil-infused groups. Total n-3 PUFA content of meat (including ALA and SDA) increased from 39 mg to 119, 129, 121 and 150 (sem 12·3) mg/100 g muscle. We conclude that both oil types were effective in enhancing the EPA and DPA, but not DHA, content of meat. Furthermore, we conclude that, when balanced for precursor n-3 fatty acid supply, differences between linseed oil and echium oil in enriching meat with LC n-3 PUFA were of little, if any, nutritional significance.

SummaryThe effect of chronic ethanol ingestion on fatty acid composition of plasma, erythrocyte and platelet phospholipids and on plasma 6-keto-PGF1α was studied. Two groups of alcoholic subjects, one of them with chronic liver disease, were studied and compared to a control group of healthy subjects. Linoleic acid was not affected by alcoholism but its larger metabolites arachidonic acid (20:4n6) and docosatetraenoic acid (22: 4n6) tended to be lower in erythrocytes and platelets of both groups of alcoholic patients; the decrease was more marked in the presence of chronic liver disease. Docosahexaenoic acid (22:6n3) was markedly decreased in plasma, erythrocytes and platelets obtained from alcoholic patients with chronic liver disease. Plasma levels of 6-keto-PGF1α, a metabolite of prostacyclin (PGI2), remained unchanged. We conclude that chronic ethanol ingestion induces important changes in long-chain polyunsaturated fatty acids, mainly in platelets, and that these changes are exacerbated when patients suffer from chronic liver disease.
