Understanding Cholesterol and Why It Matters
Cholesterol is a waxy, fat-like substance that is found in all of our body's cells. We get cholesterol from two places - our liver produces it, and we also get it from foods that come from animals, like meat, eggs, and dairy products.
Cholesterol is essential for many bodily functions. It helps make hormones, vitamin D, substances that help you digest foods, and more. But too much cholesterol in your blood can increase your risk for heart disease and stroke.
The Two Types of Cholesterol
There are two main types of cholesterol:
- LDL cholesterol - the "bad" kind that can build up in artery walls
- HDL cholesterol - the "good" kind that carries cholesterol back to the liver where it can be removed from the body
When you get your cholesterol tested, you'll get readings for your total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides (another form of fat in your blood).
Ideal Cholesterol Levels
Here are the ideal levels, according to the American Heart Association:
- Total cholesterol: less than 200 mg/dL
- LDL cholesterol: less than 100 mg/dL
- HDL cholesterol: 60 mg/dL or higher
- Triglycerides: less than 150 mg/dL
How Lifestyle Changes Can Improve Cholesterol
In many cases, high cholesterol can be improved through lifestyle changes like:
- Following a heart-healthy diet low in saturated and trans fats
- Exercising regularly
- Losing extra weight
- Quitting smoking
Making smoothies is one delicious way to easily add heart-healthy nutrients to your diet.
Ingredients to Create a Cholesterol-Busting Smoothie
Here are some of the best ingredients to add to smoothies when your goal is getting cholesterol under control:
Oats
Oats contain a soluble fiber called beta-glucan which has been shown to help reduce both total and LDL "bad" cholesterol levels. The fiber binds to cholesterol-rich bile acids in your digestive system and escorts them out of the body before they can be reabsorbed.
Almonds
Almonds are loaded with healthy monounsaturated fats, fiber, vitamin E, magnesium and protein - a powerhouse combo for your heart and cholesterol levels. Studies show eating almonds can lower LDL cholesterol while preserving HDL "good" cholesterol.
Strawberries
The anthocyanins that give strawberries their red color are powerful antioxidants that help protect LDL cholesterol from oxidation. Oxidized cholesterol is more damaging to arteries than regular LDL. Strawberries also contain vitamin C and phytochemicals that improve heart health.
Spinach
Spinach is high in lutein, a carotenoid antioxidant thats been shown to reduce the risk for heart disease and stroke by preventing the oxidation of LDL particles. The folate in spinach also decreases blood levels of homocysteine, an inflammatory factor linked to cardiovascular issues.
Ground Flaxseed
Flaxseed is one of the richest sources of plant-based omega-3 fats called ALA. Studies demonstrate that adding flaxseed to your diet can lower total cholesterol and LDL while protecting HDL levels. The fiber in flax also binds to bile acids, just like oat fiber.
Cocoa Powder
Antioxidant flavonoids called cocoa flavanols in cacao help relax blood vessels, increase blood flow, and make platelets less likely to stick together and form clots. Multiple studies confirm dark chocolate or cocoa powder can significantly reduce LDL oxidation and improve cholesterol levels.
Tart Cherries
Tart cherries contain antioxidant plant compounds called anthocyanins that help decrease cholesterol oxidation and inflammation in arteries. Studies in animals fed tart cherry powder had marked reductions in total cholesterol and triglycerides.

Tips for Continued Success Improving Your Cholesterol
Drinking smoothies is a tasty way to help lower your cholesterol, but works best as part of an overall heart-healthy lifestyle. Here are some extra tips:
Increase soluble fiber
Soluble fiber has been proven particularly effective at reducing LDL cholesterol levels. Focus on eating more oats, barley, legumes, Brussels sprouts, apples, pears, and prune juice.
Eat more plant sterols
Plant sterols are compounds found naturally in plants that block the absorption of cholesterol. The top sources are pistachios, cashews, pumpkin seeds, lentils, beans, asparagus, olive oil, and avocado.
Lose weight if overweight
Weight loss boosts HDL, lowers LDL, triglycerides, and total cholesterol while also fighting inflammation and improving heart health. A loss of just 5-10% of your current weight can make a big difference.
Exercise 30+ minutes most days
Regular aerobic exercise such as brisk walking, swimming, or cycling increases HDL, lowers triglycerides, and keeps weight and other cardiac risk factors in check.
Limit saturated fat and sugar
Eating less saturated fat (especially from red meat and dairy) and sugar is key for reducing cholesterol long-term without medications.
Sticking with cholesterol-fighting smoothies along with other heart-healthy changes can help get your numbers where they need to be and keep your cardiovascular system strong.
FAQs
What ingredients are best for lowering cholesterol in smoothies?
Some of the top ingredients to add to cholesterol-busting smoothies are oats, almonds, strawberries, spinach, ground flaxseed, cocoa powder, and tart cherries. These foods contain soluble fiber, healthy fats, and antioxidants shown to reduce LDL and total cholesterol.
How often should I drink a smoothie for cholesterol?
Aim to drink a cholesterol-lowering smoothie every day as part of a heart-healthy diet. Consistently consuming the right foods and nutrients can help keep cholesterol levels in check over time without medication.
Can smoothies significantly improve my cholesterol?
Smoothies along won't lower cholesterol a lot, but they help. Studies show people who added antioxidant-rich berry smoothies to a low-fat diet for 8 weeks dropped LDL levels by an average of 10 mg/dL more compared to diet alone.
What else can I do to lower high cholesterol besides smoothies?
Smoothies work best combined with other lifestyle changes like exercising more, losing extra weight, eating more soluble fiber from whole foods, limiting sugar and saturated fat, and potentially taking cholesterol medication if levels remain uncontrolled.
