Do combined cholesterol-lowering foods lower bad cholesterol?
The claim, precisely: portfolio dietary pattern (combined cholesterol-lowering foods) decreases LDL cholesterol
Yes, stacking proven foods lowers it additively, approaching a low-dose statin's effect.

How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."

How the studies fall
What the evidence shows
Combining evidence-based cholesterol-lowering foods (plant sterols, viscous fiber, soy protein, nuts) lowers LDL, non-HDL, ApoB, CRP and BP — additively, approaching a low-dose statin. The intellectual template for the bakery's stack-the-levers strategy.

| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Glenn 2023 · Circulation | observational | supports | high | 3 cohorts: higher Portfolio Diet Score associated with lower total CVD, CHD and stroke risk |
| Chiavaroli L, et al. (Sievenpiper) 2018 · Prog Cardiovasc Dis | meta-analysis | supports | high | MA of controlled trials: significant LDL/non-HDL/apoB/CRP/BP reductions |
| Kavanagh 2025 · BMC Med | observational | supports | moderate | NHANES cohort: greater Portfolio Diet adherence associated with lower CVD mortality |
| Jenkins DJ, et al. 2003 · JAMA | RCT | supports | moderate | RCT vs lovastatin: combined-foods diet lowered LDL & CRP near statin |
