Abstract

Long-chain n-3 PUFA from fish oils are known to have anti-inflammatory effects. We evaluated the effect of alpha-linolenic acid (ALA), precursor of n-3 fatty acids, on serum inflammatory markers and soluble cellular adhesion molecules (sCAM) of dyslipidaemic males, relative to their background diet. Participants were assigned to two groups, based upon food intake patterns: (a) twenty-one dyslipidaemic subjects who habitually ate a Mediterranean-Cretan-type diet; (b) nineteen dyslipidaemic subjects who normally ate a Westernised Greek diet. All were supplemented with 8.1 g ALA/d for 12 weeks. We determined serum amyloid A (SAA), C-reactive protein (CRP), macrophage colony-stimulating factor (MCSF), IL-6, soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 and soluble E-selectin concentrations at the beginning and the end of the ALA supplementation period. Serum baseline concentrations of inflammatory markers and sCAM were similar across the diet groups. Type of diet had a significant impact on the response of inflammatory markers to ALA supplementation. The Westernised Greek diet group showed a reduction in SAA (P<0.001), CRP (P=0.002), MCSF (P=0.005) and IL-6 (P=0.04) concentrations. The Mediterranean-Cretan-type background diet group showed a significant reduction only in MCSF concentrations (P=0.003). The sVCAM-1 concentrations were significantly reduced in both the Westernised Greek diet group (P=0.001) and the Mediterranean-Cretan-type diet group (P<0.001). The present study demonstrated that ALA supplementation lowered the serum concentrations of inflammatory markers more profoundly when the background diet was rich in saturated fatty acids and poor in MUFA.

  • In men aged 25-60 years, 5-week diets rich in stearic acid or in lauric, myristic and palmitic acids increase CRP, fibrinogen, IL-6 and sE-selectin concentrations compared with an oleic acid-enriched diet.

    “An intervention study feeding diets rich in stearic acid (18 : 0) or in lauric, myristic (14 : 0) and palmitic acids to men aged 25 -60 years for 5 weeks showed higher concentrations of CRP, fibrinogen, IL-6 and sE-selectin compared with a diet enriched in oleic acid (18 : 1n-9) (586)”
  • In healthy men, a 5-week trans-fatty acid-enriched diet results in higher CRP and IL-6 concentrations than diets rich in oleic acid, stearic acid, or the combination of lauric, myristic and palmitic acids.

    “In a 5-week intervention in healthy men, a transfatty acid-enriched diet resulted in higher CRP and IL-6 concentrations than diets rich in oleic acid, stearic acid or the combination of lauric, myristic and palmitic acids (586)”
  • In the same intervention, sE-selectin concentration is higher after the trans-fatty acid diet than in all other dietary groups, including the stearic acid and lauric+myristic+palmitic groups.

    “Furthermore, the concentration of sE-selectin was higher than in all other dietary groups including the stearic acid and lauric þ myristic þ palmitic groups.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
