Adequate intake of fiber-rich foods may help guard against peripheral arterial disease in men.

​This study evaluated the association between habitual consumption of dietary fiber and the odds of developing peripheral arterial disease (PAD). With the aid of validated food frequency questionnaires, researchers collated and analyzed data on the fiber intake levels of more than 40,000 men for 12 years. Each subject's risk of acquiring peripheral arterial disease was also assessed. 

Researchers found out that regular intake of fiber-rich foods lowered the risk of developing peripheral arterial disease. The results of this study support the theory that a high-fiber diet may confer men with significant protection against peripheral arterial disease.
