Consumption of sufficient quantities of oat products has been shown to reduce host cholesterol and thereby modulate cardiovascular disease risk.

The data is so compelling that the US FDA (FDA) approved heart health claims for oat beta-glucan on the assumption that 4 servings a day would reduce cardiovascular disease risk.

Cardiovascular diseases (CVDs) are the number 1 cause of death globally, taking an estimated 17.9 million lives each year.
