Heterogeneous responsiveness of normolipemic women to n-3 long chain fatty acid supplementation. Changes in serum lipids and apoproteins.
The effect of 10 day-low dosage of n-3 long chain fatty acids (390 mg/day of EPA and 252 mg/day of DHA) on lipid and apolipoprotein (Apo) concentrations has been studied in nine normolipidaemic women aged 28.9 +/- 4.2 years. n-3 fatty acid supplementation did not significantly decrease total cholesterol and triglyceride levels but markedly decreased the Apo A1 and Apo B concentrations (12.7%, p < 0.01 and 23.1%, p < 0.001, respectively), while the Apo A1/Apo B ratio significantly increased (14.8%, p < 0.02). In contrast to the individual variations found for triglycerides and cholesterol, Apo changes indicate a fairly homogeneous response to the fish oil supplement. In seven women Apo A1 decreased (> 10%), whereas Apo B decreased (> 10%) in all of them. The Apo A1/Apo B ratio increased (> 10%) in five of these nine women. Changes in Apo A-1 and Apo B did not significantly correlate with changes in serum lipids. These findings suggest that short-term supplementation with low amount of n-3 long chain fatty acids, EPA and DHA, influences the serum Apo content more than the lipid levels in normolipidaemic women.
