Abstract

The consumption of high levels of saturated fat over the course of several weeks may lead to exaggerated cardiovascular reactivity. The consumption of a single high-fat meal has been associated with a transient impairment of vascular function. In a randomized, repeated measures, crossover study we tested whether the consumption of a single high-fat meal by healthy, normotensive participants would affect cardiovascular reactivity when compared with an isocaloric, low-fat meal. Thirty healthy participants ate a high-fat (42 g) and a low-fat (1 g) meal on 2 separate occasions, and their cardiovascular response to 2 standard laboratory stressors was measured. Systolic blood pressure, diastolic blood pressure, and total peripheral resistance were greater in participants following the consumption of the high-fat meal relative to the low-fat meal. The findings of the present study are consistent with the hypothesis that even a single high-fat meal may be associated with heightened cardiovascular reactivity to stress and offer insight into the pathways through which a high-fat diet may affect cardiovascular function.

    A consistent hemodynamic response to the meals emerged across tasks.

    “Although the tasks were designed to elicit different patterns of reactivity (e.g., the mental arithmetic task often elicits a greater change in heart rate, whereas blood pressure reactivity is often greater during the cold pressor task), a consistent hemodynamic response to the meals emerged.”

  • Findingown data

    Total peripheral resistance was greater after the high-fat meal than after the low-fat meal.

    “In addition, RM-ANOVA conducted on the hemodynamic variables underlying changes in BP revealed a main effect of meal on TPR (P ¼ 0.05), such that overall TPR was greater after subjects consumed the high-fat compared with the low-fat diet (Fig. 1C).”

    SBP reactivity to the stress tasks was greater after the high-fat meal than after the low-fat meal.

    “Results of the RM-ANOVA revealed significant interaction effects between meal and task for SBP (P , 0.05) and DBP (P , 0.01), reflecting increased reactivity to the stress tasks after intake of the high-fat rather than the low-fat meal but no effects of the meals on baseline values (Fig. 1A), (Fig. 1B).”

  • A single meal high in saturated fat causes immediate increases in triglycerides, oxidative stress, and inflammation, with corresponding post-meal worsening of endothelial dysfunction, vasoconstriction, and systolic blood pressure.

    “Recent studies of healthy individuals indicate that a single meal high in saturated fat will cause immediate increases in triglycerides, oxidative stress, and inflammation, which causes corresponding post-meal worsening of endothelial dysfunction, vasoconstriction, and systolic blood pressure (11,12).”

    From Dietary Strategies for Improving Post-Prandial Glucose, Lipids, Inflammation, and Cardiovascular Health (2008) · cites this paper as [11]

    The Discussion (page not provided) reports greater systolic blood-pressure and total peripheral resistance responses to psychological stress after a single high-fat meal. The Introduction (page not provided) reports earlier findings linking a high-fat meal to impaired vascular function and elevated triglycerides to endothelial dysfunction. This paper does not establish immediate increases in oxidative stress or inflammation, or that those changes cause the vascular and blood-pressure effects; its blood-pressure finding concerns reactivity to stress, not a general post-meal rise. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Excessive ingestion of calorie-dense, easily digestible foods causes abnormal surges in blood glucose and triglyceride levels.

    “Excessive ingestion of calorie-dense, easily digestible foods causes abnormal surges in blood glucose and triglyceride levels (11)(12)(13).”

    From Dietary Strategies for Improving Post-Prandial Glucose, Lipids, Inflammation, and Cardiovascular Health (2008) · cites this paper as [11]

    The Introduction reports increased blood triglyceride concentrations in a cited two-week high-fat-diet study. It does not report blood-glucose surges, and the Study limitations section says this paper did not measure triglyceride levels after its test meals. The claim therefore extends the reported triglyceride finding to an acute effect of calorie-dense, easily digestible foods and adds an unsupported glucose effect. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Favored protein sources in the modern diet, such as ground beef, sausage, bacon, and cheese, are high in calories and saturated fats and tend to worsen postprandial dysmetabolism.

    “Unfortunately, the favored protein sources in the modern diet, such as ground beef, sausage, bacon, and cheese, are high in both calories and saturated fats and tend to worsen post-prandial dysmetabolism (3,11).”

    From Dietary Strategies for Improving Post-Prandial Glucose, Lipids, Inflammation, and Cardiovascular Health (2008) · cites this paper as [11]

    The Procedure section describes a sausage-containing fast-food meal with 820 kcal and 17 g of saturated fat, supporting the claim for an example of a calorie-dense, saturated-fat-containing food. But the comparison meal had similar calories, and the Study limitations section says triglyceride and lipoprotein levels were not measured. The paper found increased cardiovascular reactivity after the high-fat meal; it does not establish that the listed protein sources worsen postprandial dysmetabolism. (LLM, conf=0.85)

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • TPR reactivity is claimed despite a nonsignificant meal-by-task interaction

    Major

    The discussion describes significantly enhanced TPR reactivity after the high-fat meal. The results report a meal effect on overall TPR but explicitly state that the meal-by-task interaction for TPR was not significant, so the reported analysis does not establish a significant difference in TPR response to the tasks.

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.
