How the 'Portfolio Diet' May Help Lower Cholesterol, Heart Disease Risk

The Portfolio Diet has been shown to reduce the risk of death from heart disease by up to 18%.

While well-known diets like the Mediterranean and DASH have gained widespread recognition for their health benefits, a lesser-known diet is gaining attention for its ability to promote heart health. The Portfolio Diet, developed in 2003, combines four specific cholesterol-lowering food categories for a powerful "additive effect." This combination has been linked to a reduction in cardiovascular disease mortality and all-cause mortality.

The Portfolio Diet's success can be attributed to its unique blend of ingredients, including:

  • Plant sterols that lower cholesterol levels
  • Soluble fiber that binds and removes bile/cholesterol
  • Unsaturated fats

This combination creates an "additive" effect in lowering cholesterol, setting the Portfolio Diet apart from other heart-healthy diets. According to Wellstar cardiovascular dietitian Erin Sheehan, "When it comes to looking specifically at lowering (bad) LDL cholesterol, that's where the portfolio diet really shines."

**Long-term Health Effects of the Portfolio Diet**

Researchers have demonstrated that adherence to the Portfolio Diet can positively impact heart health. A 2023 peer-reviewed study published in the American Heart Association (AHA) journal Circulation found that moderate adherence to the Portfolio Diet could decrease the risk of mortality from cardiovascular disease and coronary heart disease by 12% and 14%, respectively. Overall mortality dropped by 12%.

However, the closer someone followed the diet, the higher those numbers increased, to 16% and 18% reductions in mortality for cardiovascular and coronary heart disease, respectively. Overall mortality dropped by 14%. This is a surprising and "impressive" result, according to Chandan Devireddy, MD, an interventional cardiologist with Emory Healthcare.

**Getting Started with the Portfolio Diet**

Like any diet looking to improve heart health, people should avoid foods that are highly processed and contain added sugar. Consistent, small additions (like nuts or beans) can offer great results, even with moderate adherence. By incorporating the Portfolio Diet into your lifestyle, you may be able to delay the onset of cardiovascular events by as much as 13 years.
