Which of the following is NOT a common contributor to hypertension?

High fiber intake is considered beneficial rather than a contributor to hypertension. In fact, a diet rich in dietary fiber is often associated with various health benefits, including improved cardiovascular health. Fiber helps manage cholesterol levels, supports healthy digestion, and can aid in maintaining a healthy weight, all of which are important factors in preventing hypertension.

Conversely, insulin resistance, chronic dehydration, and insufficient magnesium are known to have direct links to the development or exacerbation of hypertension. Insulin resistance can lead to increased blood pressure through various metabolic pathways, chronic dehydration can result in the body retaining more sodium and increasing blood pressure, and insufficient magnesium is associated with vascular function and regulation of blood pressure. Thus, while the other options are linked with factors contributing to hypertension, high fiber intake serves a protective role.
