A surprisingly effective diet,developed in the early 2000s,could lower yoru risk of cardiovascular disease by 16% and premature death by 14%. Known as the portfolio diet, it focuses on adding specific foods-not restricting them-to actively reduce “bad” cholesterol and boost overall health, especially for those over 60.
The portfolio Diet: A Food ‘Portfolio’ for Longevity

This dietary approach prioritizes foods that lower LDL cholesterol without the drastic measures frequently enough associated with heart-healthy eating. Here’s what makes it unique:
- It doesn’t ban any foods, but encourages a strategic selection of cholesterol-lowering options.
- Studies show significant reductions in LDL cholesterol within just four weeks of starting the diet.
- Long-term adherence is linked to a lower risk of cardiovascular disease and premature death.
what Exactly *Is* the Portfolio Diet?
Unlike restrictive diets, the portfolio diet isn’t about deprivation.It’s about building a “food portfolio,” choosing foods that work synergistically to improve your health. Andrea Glenn, a registered dietitian and assistant professor of nutrition at New York University, explains: “It gets its name because it’s like a business portfolio: you can choose the components you like.” The core components are straightforward:
- Plant proteins: tofu,soy milk,legumes
- Nuts and seeds: almonds,cashews,flax or chia seeds
- Fruits and vegetables: apples,berries,persimmons,assorted vegetables
- Whole grains: oats,barley
- Heart-healthy oils: olive,rapeseed,sunflower,safflower
- Avocados for Healthy Fats
- Plant sterols: present in certain fortified foods
To maximize benefits,the diet suggests aiming for 50 g of plant proteins,45 g of nuts and seeds,45 g of healthy oils,20 g of fiber,and 2 g of plant sterols daily. The focus is on *adding* beneficial foods, rather than eliminating favorites.
Dramatic Effects on Cholesterol and Beyond
The first evidence of the portfolio diet’s effectiveness emerged in 2003. A study led by David Jenkins and his team demonstrated that participants with high cholesterol experienced a 35% reduction in LDL cholesterol after only four weeks. Subsequent research has consistently validated these findings. A 2025 study published in BMC Medicine, following 14,835 adults for 22 years, revealed that those most closely adhering to the portfolio diet had a 16% lower risk of dying from cardiovascular disease and a 14% lower risk of premature death from all causes. This diet doesn’t simply address cholesterol; it directly impacts longevity and heart health.
The benefits extend beyond cholesterol reduction. The portfolio diet has also been linked to decreased inflammation, a drop in blood pressure, and improved blood sugar control. As an example, a 2024 study involving patients with type 2 diabetes showed a significant reduction in HbA1c-a measure of average blood sugar-over six months. An earlier 2021 study found that men following this diet had a 28% less risk of dying prematurely or developing cancer over a ten-year period.
Adopting the Portfolio Diet After 60
While the goal of 50 g of plant-based protein daily might seem daunting, experts recommend a gradual approach.Simple swaps-replacing rice with barley,using vegetable oils instead of butter,and slowly increasing fiber intake to avoid digestive discomfort-can make a significant difference. Even incorporating key principles, like adding more fruits and vegetables or regularly consuming nuts, can positively impact health without strict adherence to all recommendations.
Long-term data is compelling. A 30-year American study of 210,240 adults showed that individuals whose diets most closely resembled the portfolio model had a reduced risk of cardiovascular disease, coronary heart disease, and stroke. This evidence confirms that the portfolio diet isn’t a fleeting trend,but a lasting and preventative dietary model that can enhance quality of life,especially after age 60.
