Dietary fiber intake has been shown to have modest effect in lowering cholesterol. However, most of these studies were done with 20g/daily fiber intake. Not much is known about high dietary fiber intake (30-40 g/day) and serum cholesterol. Also, there have been small studies that have shown modest decrease in oxidative stress by increasing dietary fiber intake. The goal of our study is to determine the efficacy /safety of high dietary fiber intake in raising HDL, lowering LDL, and lowering oxidative stress in patients with hyperlipidemia.
