What health condition is associated with a low fiber intake?

The association between low fiber intake and specific health conditions is well-documented, particularly regarding cardiovascular health. A low fiber intake can contribute to poor dietary habits that may lead to the stiffening of arteries, including those supplying blood to the brain. This condition, known as arterial stiffness, can subsequently increase the risk of various cardiovascular problems, including hypertension and stroke.

Fiber plays a crucial role in maintaining cardiovascular health. It aids in regulating cholesterol levels and blood pressure, both of which are vital for keeping arteries supple and flexible. Diets low in fiber often lack the essential nutrients and protective compounds found in whole plant foods, contributing to the risk of developing stiff arteries. Addressing dietary patterns to increase fiber intake can help mitigate these risks, supporting overall vascular health.

In contrast, while weight gain, increased risk for diabetes, and high cholesterol levels are indeed associated with low fiber intake, these conditions more directly reflect metabolic dysregulation rather than specifically indicating arterial health as the primary concern.
