<h4 class="dechead">On One Hand: Sugar as the Causative Agent
Researchers Harry Preuss and Joseph Knapka reported that in a rat model, consumption of sugar led to increased sodium retention and elevated blood pressure. Similarly, Sanchez-Lozada et al found that a progressively higher fructose intake resulted in kidney hypertrophy, glomerular hypertension and cortical vasoconstriction. Metabolic syndrome induced, in part, by excess sugar consumption contributes to hypertension.
On the Other: One of Several Contributing Factors
According to the results of a study conducted by Milan and Mulaterro, reducing salt intake to no more than 2.4 grams per day effectively contributes to a reduction in blood pressure. Combined with anti-hypertensive drug therapies, a low-sodium diet helps to reduce blood pressure to a normal range. Doctors sometimes minimize the importance of sodium levels on blood pressure.
Bottom Line
Excess calories in the form of simple sugars found in many drink products contribute to obesity, a risk factor for hypertension. However, the importance of limiting sodium intake should not be minimized. Under the guidance of doctors, hypertensives should limit intake of sugary drinks and sodium to maintain a healthy blood pressure.
