The Portfolio Dietary Pattern significantly reduces estimated 10-year coronary heart disease (CHD) risk by approximately 13% compared to a standard NCEP Step II diet.

Following the Portfolio Dietary Pattern not only lowers cholesterol but also reduces your estimated 10-year risk of having a coronary heart disease event by about 13%. This benefit is calculated based on improvements in cholesterol, blood pressure, and inflammation markers achieved by consuming specific plant-based foods daily alongside a standard low-saturated-fat diet.
