LDL cholesterol of 120: what it means and how to lower it

Ranked by an overall score that blends how much of your gap the lever could close, how doable it is, how strong the evidence is, and how accessible it is. Effects are population averages and are partly overlapping — this is a menu, not a checklist to do all at once.

1. 1

   Cut saturated fat, replace with unsaturated

   Diet

   ~9%

   typical LDL cholesterol drop

   Evidence A

   The swap matters: replace butter/red meat with olive oil, nuts and fish — replacing it with refined carbs undoes the LDL benefit.

   Source: Hooper 2020 (Cochrane) · 15 RCTs, 56,675 participants: cutting saturated fat for at least two years reduced combined cardiovascular events by 17% (RR 0.83, 95% CI 0.70–0.98), with greater reductions in saturated fat producing greater reductions in events.

2. 2

   Plant sterols / stanols (2 g/day)

   Supplement

   ~9%

   typical LDL cholesterol drop

   Evidence A

   Benefit plateaus above ~2–3 g/day. Works through a different mechanism than fiber, so it adds a bit on top of it.

   Source: Ras 2014 (Br J Nutr) · 124 studies: plant sterol/stanol intakes of 0.6–3.3 g/day lowered LDL by 6–12%, with the effect rising up to about 3 g/day and then plateauing.

3. 3

   Viscous fiber — psyllium (~10 g/day)

   Fiber

   ~7%

   typical LDL cholesterol drop

   Evidence A

   Fiber levers are sub-additive — stacking psyllium, oats and beans won't simply add up. Build up the dose slowly to avoid bloating.

   Source: Jovanovski 2018 (Am J Clin Nutr) · 28 RCTs, 1,924 participants: a median 10.2 g/day of psyllium lowered LDL by 0.33 mmol/L (~13 mg/dL), non-HDL by 0.39 mmol/L and apolipoprotein B by 0.05 g/L.

4. 4

   Oat beta-glucan (~3 g/day)

   Fiber

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Counts toward the same viscous-fiber effect as psyllium, not on top of it. ~3 g beta-glucan ≈ a bowl and a half of oats.

   Source: Whitehead 2014 (Am J Clin Nutr) · 28 RCTs: at least 3 g/day of oat beta-glucan lowered LDL by 0.25 mmol/L (~10 mg/dL) and total cholesterol by 0.30 mmol/L, with no significant effect on HDL or triglycerides.

5. 5

   Bergamot polyphenol supplement

   Supplement

   ~15%

   typical LDL cholesterol drop

   Evidence C

   Promising but the evidence is low-quality and short-term. Not a statin substitute; quality varies between brands.

   Source: Lamiquiz-Moneo 2020 (Crit Rev Food Sci Nutr) · 12 human studies: 75% showed a significant LDL reduction, ranging 7.6% to 40.8% — but the authors note the designs were heterogeneous and the scientific quality of the studies was 'quite limited'.

6. 6

   Regular aerobic exercise

   Lifestyle

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Genuinely lowers LDL, but modestly — pooled across 148 trials it is about 5%, alongside a similar drop in triglycerides. Do it for your overall cardiovascular risk; it will not close a large ApoB gap on its own.

   Source: Smart 2025 (Sports Med) · 148 RCTs, 8,673 participants: exercise training lowered LDL by 7.22 mg/dL (95% CI −9.08 to −5.35) and triglycerides by 8.01 mg/dL (95% CI −10.45 to −5.58) — 'significant but modest' 3.5–11.7% improvements. Trial sequence analysis found the evidence base has reached futility, meaning further trials are unlikely to overturn it.

7. 7

   Tree nuts / almonds (~45 g/day)

   Diet

   ~4%

   typical LDL cholesterol drop

   Evidence B

   Modest on its own. Best as a replacement for refined snacks, not added on top of your current calories.

   Source: Del Gobbo 2015 (Am J Clin Nutr) · 61 controlled trials, 2,582 participants: each 28.4 g/day serving lowered LDL by 4.8 mg/dL, apolipoprotein B by 3.7 mg/dL and triglycerides by 2.2 mg/dL.

8. 8

   Lose 5–10% of body weight (if overweight)

   Lifestyle

   ~5%

   typical LDL cholesterol drop

   Evidence A

   Bigger effect on ApoB and triglycerides than on LDL, and the hardest lever to sustain — but it improves many risk factors at once.

   Source: Hasan 2020 (J Clin Endocrinol Metab) · 73 RCTs, 32,496 adults: each kilogram lost lowered triglycerides by 4.0 mg/dL and LDL by 1.28 mg/dL at 12 months. The review did not measure apolipoprotein B.

9. 9

   Cut refined carbs & added sugar

   Diet

   ~3%

   typical LDL cholesterol drop

   Evidence B

   Lowers triglycerides and, by a few percent, LDL — and not just by way of weight loss. What replaces the carbs still matters: swapping them for saturated fat can push LDL back up.

   Source: Te Morenga 2014 (Am J Clin Nutr) · 37 lipid trials: higher versus lower free-sugar intake raised triglycerides by 0.11 mmol/L and LDL by 0.12 mmol/L (P = 0.0001). The relation was strongest in trials that held energy intake constant, and the authors conclude it is independent of any effect of sugar on body weight.

10. 10

    Soy protein (~25 g/day)

    Diet

    ~4%

    typical LDL cholesterol drop

    Evidence B

    Small, well-tolerated effect — most useful when soy displaces animal protein and its saturated fat.

    Source: Blanco Mejia 2019 (J Nutr) · 43 trials identified by the FDA: a median 25 g/day of soy protein lowered LDL by 4.76 mg/dL, about 3–4%, versus non-soy protein controls.
