High LDL cholesterol is one of the main drivers of heart attacks and strokes, yet it causes no symptoms. The only way to know your numbers is a simple blood test. If yours are higher than they should be, diet and lifestyle changes can make a real difference. In clinical trials, combining several cholesterol-lowering foods reduced LDL by up to 20–30%. Here is how to lower cholesterol naturally, step by step.
Understanding your cholesterol numbers
| Measure | Desirable level (adults) | What it means |
|---|---|---|
| LDL cholesterol | Below 100 mg/dL (2.6 mmol/L) | “Bad” cholesterol that builds up in artery walls |
| HDL cholesterol | 40+ mg/dL in men, 50+ in women | “Good” cholesterol that helps clear excess cholesterol |
| Triglycerides | Below 150 mg/dL (1.7 mmol/L) | Blood fats raised by excess sugar, alcohol and calories |
| Total cholesterol | Below 200 mg/dL (5.2 mmol/L) | Overall amount; less useful than LDL alone |
Most adults should have a cholesterol check every 4–6 years from age 20, and more often if they have risk factors.
10 ways to lower cholesterol naturally
1. Eat more soluble fiber
Soluble fiber forms a gel in the gut that binds cholesterol-rich bile and carries it out of the body. Getting 5–10 grams of soluble fiber a day can lower LDL by around 5%. Good sources: oats, barley, beans, lentils, apples, citrus fruit, Brussels sprouts and psyllium husk.
2. Swap saturated fats for unsaturated fats
Saturated fat, found in fatty meat, butter, cheese, cream, coconut oil and palm oil, raises LDL more than anything else you eat. The American Heart Association suggests keeping it to about 6% of calories for people who need to lower LDL. Replace it with olive oil, rapeseed (canola) oil, avocados, nuts and oily fish.
3. Avoid trans fats
Trans fats both raise LDL and lower HDL. Many countries have banned artificial trans fats, but check labels for “partially hydrogenated oils” in imported snacks, pastries and fried foods.
4. Add plant sterols and stanols
These plant compounds block cholesterol absorption. About 2 grams a day, usually from fortified spreads, yogurts or drinks, lowers LDL by roughly 8–10%.
5. Eat a handful of nuts daily
About 30–45 g (1–1.5 oz) of almonds, walnuts, pistachios or other nuts a day modestly lowers LDL and provides healthy fats, fiber and magnesium.
6. Include soy foods
Tofu, edamame, tempeh and soy milk can lower LDL by a few percent, partly by replacing higher-fat animal protein.
7. Move more
Regular aerobic exercise raises HDL and lowers triglycerides. Aim for 150 minutes a week of moderate activity plus two strength sessions; see our strength training guide for beginners.
8. Lose excess weight
Losing 5–10% of body weight lowers triglycerides and LDL and raises HDL.
9. Cut back on sugar and alcohol
Both strongly raise triglycerides. Sugary drinks, sweets, refined carbs and regular heavy drinking are the main culprits.
10. Stop smoking
Quitting raises HDL and quickly reduces the damage smoking does to artery walls, multiplying the benefit of every other change.
The “portfolio” approach
Researchers at the University of Toronto tested a “portfolio diet” combining soluble fiber, nuts, soy protein and plant sterols. In a small trial, it lowered LDL by about 29%, similar to an older statin drug at the dose tested. The lesson: individual foods have modest effects, but together they add up.
What about eggs and dietary cholesterol?
For most people, cholesterol in food has a smaller effect on blood cholesterol than saturated fat does. Eggs can fit into a heart-healthy diet in moderation. People with diabetes or very high LDL may be advised to limit them.
Do supplements help?
- Psyllium has good evidence for lowering LDL.
- Plant sterol supplements work similarly to fortified foods.
- Omega-3 fish oil lowers triglycerides but not LDL; read more in our guide to omega-3 benefits.
- Red yeast rice contains a natural statin compound, so it carries the same side-effect risks and quality varies widely. Do not use it without medical advice.
When lifestyle changes are not enough
Some people inherit very high cholesterol (familial hypercholesterolemia), and diet alone cannot fix it. If your LDL stays high after three to six months of changes, or you have heart disease or diabetes, statins and other medications are safe, well-studied and highly effective. Lifestyle changes still add benefit on top.
Frequently asked questions
How fast can you lower cholesterol naturally?
Diet changes can lower LDL noticeably within 4–6 weeks. Most doctors re-test after about three months.
What drink lowers cholesterol?
Oat drinks containing beta-glucan, soy milk and sterol-fortified yogurt drinks can contribute. Water and unsweetened tea are better choices than sugary drinks.
Can thin people have high cholesterol?
Yes. Genetics play a major role, so everyone should get tested regardless of weight.
