Hypertension is a major health problem worldwide. Its attendant morbidity and mortality complications have a great impact on
patient’s quality of life and survival. Optimizing blood pressure control has been shown to improve overall health outcomes. In
addition to pharmacological therapies, nonpharmacological approach such as dietary modification plays an important role in
controlling blood pressure. Many dietary components such as sodium, potassium, calcium, and magnesium have been studied
substantially in the past decades. While some of these nutrients have clear evidence for their recommendation, some remain
controversial and are still of ongoing study. Dietary modification is often discussed with patients and can provide a great benefit
in blood pressure regulation. As such, reviewing the current evidence will be very useful in guiding patients and their physician
and/or dietician in decision making. In this review article of nutritional factors in hypertension management, we aim to examine
the role of nutritional factors individually and as components of whole dietary patterns.
