Abstract

Background Persons following current dietary guidelines have a lower risk of mortality from coronary heart disease.Objective The objective was to compare the short-term effect of a high-fat meal and a high-carbohydrate meal, with and without dietary antioxidants, on vasomotor, antiplatelet, and hemostatic functions of the endothelium in healthy subjects.Design In an observer-blinded, randomized crossover study, 25 (13 men and 12 women) healthy subjects were given each of 3 meals in random order at 1-wk intervals: a high-fat meal (760 kcal), an isoenergetic high-carbohydrate meal, and a high-fat meal with dietary antioxidants from vegetables (865 kcal). Endothelial functions, as assessed by hemodynamic and rheologic responses to L-arginine--the natural precursor of nitric oxide--were evaluated before and 4 h after each meal.Results Unlike the high-carbohydrate meal, the high-fat meal increased the plasma concentrations of triacylglycerol (P < 0.01); both meals activated hemostasis. The high-carbohydrate meal did not modify blood pressure, and platelet aggregation decreased in response to the L-arginine load (-7.1 +/- 2.3 mm Hg and -8.5 +/- 4.5%, respectively). After the high-fat meal, the decrease in blood pressure in response to L-arginine was reduced (-1 +/- 0.8 mm Hg), and platelet aggregation showed a paradoxical increase (4.1 +/- 2.1%; P < 0.01 compared with the high-carbohydrate meal). The high-fat meal with antioxidants partially restored the vascular response to L-arginine.Conclusion Compared with a high-carbohydrate meal, a high-fat meal can modify endothelial functions toward a more atherogenetic profile, which is partially prevented by dietary antioxidants.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Studies in experimental animals and human volunteers show that absorption of ingested Maillard reaction products is variable and dependent on the Maillard reaction product.

    “Studies in experimental animals fed or injected with radiolabelled protein-bound AGE and human volunteers receiving diets enriched with MRP or specific AGE have shown that absorption of ingested MRP is variable and dependent on the MRP (464,465,527 -529) .”

  • Highly cross-linked advanced glycation end products and melanoidins are predominantly excreted in faeces, while absorbed Maillard reaction products are generally rapidly excreted by the kidney with limited accumulation in tissues and organs.

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.
