The Portfolio Diet
research · Jenkins DJA, Kendall CWC, Marchie A, et al. Direct comparison of a dietary portfolio of cholesterol-lowering foods with a statin in hypercholesterolemic participants. American Journal of Clinical Nutrition. 2005. (2005)
A dietary pattern combining plant sterols, soy protein, viscous fiber, and nuts that lowers LDL cholesterol by 20-30%, similar to a starting dose of a statin.
Core Concepts
The Problem
High LDL cholesterol is a major modifiable risk factor for cardiovascular disease, yet many individuals are unable or unwilling to take statin medication.
The Claim
The Portfolio Diet, a food-based combination of four specific cholesterol-lowering components, can achieve clinically meaningful LDL reduction.
Key Evidence
- •Multiple randomized controlled trials show LDL reductions of 20-30%.
- •Network meta-analysis places Portfolio Diet among most effective dietary interventions for cholesterol.
Practical Implication
Offers a viable dietary intervention for individuals with hypercholesterolemia, potentially reducing need for medication.
Nuance & Limits
Real-world adherence may be lower than controlled trial conditions; the diet requires daily inclusion of all four components to achieve maximum effect.
