“… 20 , 32 This observation may be due in part to the lower BMI seen in vegetarians 22 . Lower blood pressure levels may also result from the potassium, magnesium, antioxidants, dietary fat, and fiber found in vegetarian diets 33 . Fruit and vegetable intake was responsible for about one half of the blood pressure reduction of the DASH (Dietary Approaches to Stop Hypertension) study 34 …”

Nutrition Concerns and Health Effects of Vegetarian Diets

Vegetarians exhibit a wide diversity of dietary practices, often described by what is omitted from their diet. When a vegetarian diet is appropriately planned and includes fortified foods, it can be nutritionally adequate for adults and children and can promote health and lower the risk of major chronic diseases. The nutrients of concern in the diet of vegetarians include vitamin B(12), vitamin D, ω-3 fatty acids, calcium, iron, and zinc. Although a vegetarian diet can meet current recommendations for all of these nutrients, the use of supplements and fortified foods provides a useful shield against deficiency. A vegetarian diet usually provides a low intake of saturated fat and cholesterol and a high intake of dietary fiber and many health-promoting phytochemicals. This is achieved by an increased consumption of fruits, vegetables, whole-grains, legumes, nuts, and various soy products. As a result of these factors, vegetarians typically have lower body mass index, serum total and low-density lipoprotein cholesterol levels, and blood pressure; reduced rates of death from ischemic heart disease; and decreased incidence of hypertension, stroke, type 2 diabetes, and certain cancers than do nonvegetarians.

“…Vegetarian diets rich in isoflavonoids have been reported to lower blood pressure. 13,14 Many isoflavonoids are thought to have beneficial cardiovascular effects. [15][16][17] Biochanin A is an important isoflavonoid that relaxes rabbit basilar artery 18 and induces significant gender-independent relaxation in rabbit coronary arteries in vitro.…”

1. The aim of the present study was to investigate the mechanism underlying biochanin A-induced relaxation of the aorta in spontaneously hypertensive rats (SHR). 2. The tension in isolated ring preparations of thoracic aortas from normotensive (Wistar-Kyoto (WKY) rats) and SHR at 5 and 10 weeks of age was measured isometrically. 3. Biochanin A (10(-7) to 10(-4) mol/L) induced a concentration-dependent relaxation in aortic rings from both strains at the age of 5 and 10 weeks and the relaxation was greater in rings from 10-week-old SHR compared with age-matched WKY rats. The vasorelaxation induced by biochanin A was significantly reduced by denudation of the endothelium in aortic rings from SHR, but not WKY rats. Treatment with either indomethacin, a cyclo-oxygenase inhibitor, or N(omega)-nitro-L-arginine methyl ester, a nitric oxide synthase inhibitor, had little effect on the relaxation induced by biochanin A in aortic rings from either strain. Glibenclamide, a selective inhibitor of ATP-sensitive potassium channels, significantly attenuated the relaxation induced by biochanin A in aortic rings from both strains, although the extent of reduction was greater in WKY rats than SHR. Conversely, treatment with 4-aminopyridine, a selective inhibitor of voltage-dependent potassium channels, or tetraethylammonium, an inhibitor of calcium-activated potassium channels, significantly reduced the vasorelaxation induced by biochanin A in rings from SHR but not WKY rats. 4. The greater vasorelaxation produced by biochanin A in aortic rings from 10-week-old SHR is endothelium dependent. Different mechanisms underlie the relaxant effects of biochanin A in aorta from SHR and WKY rats. The mechanisms of biochanin A-induced vasorelaxation in thoracic aortas from both normotensive and hypertensive rats involve ATP-sensitive potassium channels and, in addition, in rings from the hypertensive strain at 10 weeks of age, an endothelium-derived activation of smooth muscle cell potassium channels contributes to the vasorelaxation observed.

“…Zudem haben sie, insbesondere Veganer, durchschnittlich niedrigere Blutdruckwerte [11,12]. Eine Ursache dafür liegt in der überdurchschnittlichen Zufuhr von Kalium und Magnesium bei Vegetariern und Veganernbeide Mineralstoffe kommen reichlich in Gemüse und Obst vor [13]. Auch pflanzliches Protein wirkt, vermutlich aufgrund seiner Aminosäuren-Zusammensetzung, blutdrucksenkend [14].…”

“…Interventionen mit lakto-ovo-vegetarischer Kost (Dauer 6 Wochen) führten sowohl bei normotensiven Personen als auch bei Personen mit leicht erhöhten Blutdruckwerten zu einer Senkung des systolischen Blutdrucks um 5-6 mmHg [37]. Bei 500 Teilnehmern einer 12-tägigen Interventionsstudie bewirkte eine fettarme vegane Kost, in Kombination mit moderater körperlicher Aktivität und Stressmanagement, eine durchschnittliche Blutdrucksenkung von 6 % [38].…”
