Role of dietary components in modulating hypertension

dieta dashThe review “Role of dietary components in modulating hypertension” (Feyh A. et all., 2016) pretends to outline the effect of specific dietary components, when formulating a dietary approach to hypertension management that ultimately aims to improve patient adherence to the treatment, and achieve better control of hypertension.

Management of the hypertension reduces the risk of adverse outcomes, such as cardiovascular or cerebrovascular events, vision impairment due to retinal damage, and renal failure. In addition to pharmacological therapy, lifestyle modifications such as diet and exercise are effective in managing hypertension.

Current diet guidelines include the DASH diet, a low-fat and low-sodium diet that encourages high consumption of fruits and vegetables.  

Antihypertensive dietary components:

  • Fruits and vegetables can manage blood pressure according to their potassium content, flavonoid, polyphenol content, and fiber content.  
  • Spices, including chili peppers, cinnamon, black pepper, and turmeric, can also have antihypertensive effects.
  • Omega-3 fatty acids (n−3FAs) have been extensively studied for their cardiovascular health benefits.

While the diet is effective in controlling hypertension, adherence to the diet is poor and there are few applicable dietary alternatives, which is an issue that can arise from poor health literacy in at-risk populations.  In counseling the patient, the physician must be educated with regards to effective dietary strategies in order to present a specific and coherent dietary plan, and present the patient with a wide array of palatable options that can help encourage adherence to the intervention.
