[Dedicated to the demented moderator of "vegetarian_group" (Yahoo) and her cohorts who sent me & posted such foul e-mail when I cited another study supporting the same concept. I was concerned about a recipe posted with "10 eggs, cup of butter, and cup of milk," among other things, as being a heart attack waiting to happen. Here's a related study, and then there's Essy's research regarding reversing heart disease. Full abstract of PCRM-cited study below, and PCRM contact info as well. Go no-fat vegan!]

HIgh-Fat Fast-Food Meals Cause the Heart to Beat Harder and Blood Pressure to Rise
A new study from the Journal of Nutrition finds that a single fatty meal can cause the heart to beat harder and blood pressure to rise. Researchers at the University of Calgary analyzed the affects of either a high-fat fast-food meal (42 grams of fat) or a meal with no more than 1.3 grams of fat among 30 healthy participants. The results showed that when both groups were subjected to a series of standard stress tests, those who ate the high-fat meal saw their blood pressure go up 1.25 to 1.5 times higher than the participants who ate the low-fat meal.

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.
