Summary

Hypertension and endothelial dysfunction are being increasingly recognized as key etiological factors in the development of atherosclerosis and subsequent cardiovascular disease (CVD). A substantial body of evidence indicates that treating patients with elevated blood pressure (BP) leads to marked reduction in the risk of stroke, myocardial infarction, heart failure, and renal failure. There is also accumulating evidence associating endothelial dysfunction, which is defined as incapacity of the arteries to vasodilate when required, to elevated BP and an increased risk of CVD.

While there are more and more studies on how diet affects BP in healthy subjects, the impact of dairy consumption per se on both endothelial function and ambulatory BP has not been well characterized in patients with established essential hypertension. Therefore, the general objective of the study is to investigate in a single-blind randomized controlled study the impact of dairy consumption on ambulatory BP and endothelial function in subjects with mild to moderate essential hypertension.

Conditions

Interventions

OTHER

Dairy diet

During the DAIRY diet, subjects will be asked to incorporate 3 servings of dairy: 375 ml of reduced fat milk (1% fat), 175 g of low fat yogurt (1.5% fat) and 30g of regular cheese (34% fat) into their every day diet.

OTHER

Control diet

During the CONTROL diet of the study, participants will be asked to consume energy equivalent replacement products (290 ml of fruit juice, 156 ml of vegetable juice, 1 homemade cookie, 20g of cashew).
