Portfolio Diet proves it can protect heart health across cultures and ages

A long-standing diet designed to cut cholesterol has now been proven to work across different ethnic groups and ages. The Portfolio Diet, created in 2003 by University of Toronto professor David Jenkins, combines simple, affordable foods to reduce heart health risk. Recent studies confirm its benefits—even when followed moderately—can delay serious heart health problems by years.

The diet focuses on four key food types: plant proteins like soy, nuts, soluble fibre, and plant sterols. These ingredients work together to lower LDL cholesterol more effectively than other eating plans. Research also shows the approach is flexible, allowing gradual changes rather than strict restrictions.

In 2023, a study published in Circulation found the diet reduces the risk of stroke and heart disease. A 2025 follow-up in BMC Medicine went further, reporting an 18% drop in coronary heart disease deaths and a 16% reduction in overall cardiovascular mortality with moderate adherence. Starting the diet earlier in life could even push back the onset of heart health problems by up to 13 years.

The latest University of Toronto research examined how the diet performs across South Asian, East Asian, and White participants. It accounted for differences in typical eating habits, baseline cholesterol, and genetic risks. Despite these variations, the benefits remained consistent.

The Portfolio Diet's effectiveness spans cultures and age groups, offering a practical way to improve heart health. Its reliance on budget-friendly staples—like beans, frozen vegetables, and nuts—makes it accessible. With proven results in lowering cholesterol and extending healthy years, the diet presents a clear option for long-term prevention.
