Raised blood pressure is major preventable cause of CVD, and hypertensive people are three times more likely to develop CVD. High blood pressure increases the workload on the heart and can damage the endothelial lining of blood vessels, cause an upsurge of infiltration of lipids into the arterial wall, worsen endothelial damage and enhance atherosclerotic deposition (Thomas & Bishop, 2007). The most significant influences are obesity, excess alcohol and excess salt intake (Williams et al., 2004). Dietary modifications are proven to lower systolic and diastolic blood pressure (Apple, 1997). A review showed that among overweight hypertensive people, a weight reduction of 3–9% is associated with a decrease of about 3 mmHg in systolic and …show more content…
Raised blood pressure is major preventable cause of CVD, and hypertensive people are three times more likely to develop CVD. High blood pressure increases the workload on the heart and can damage the endothelial lining of blood vessels, cause an upsurge of infiltration of lipids into the arterial wall, worsen endothelial damage and enhance atherosclerotic deposition (Thomas & Bishop, 2007). The most significant influences are obesity, excess alcohol and excess salt intake (Williams et al., 2004). Dietary modifications are proven to lower systolic and diastolic blood pressure (Apple, 1997). A review showed that among overweight hypertensive people, a weight reduction of 3–9% is associated with a decrease of about 3 mmHg in systolic and diastolic blood pressure. In addition, weight-reducing diets may lessen the dosage requirements of antihypertensive medications (Mulrow et al., 2008). A reduction in alcohol intake lowered systolic and diastolic blood pressure by an average of 3.3 and 2.0 mmHg (Xin, He, Frontini, Ogden, Motsamai, & Whelton, 2001). On the other hand, excess sodium and inadequate potassium consumption are connected directly to hypertension, and many systems become affected, including renal function, the renin-angiotensin-aldosterone system, the atrial natriuretic factor, the sympathetic nervous system, adrenergic receptors, endothelin and nitric oxide and ion transport (Weinberger, 1996). Moreover, insulin can promote renal sodium reabsorption, a number of
