Limiting saturated fats in your diet along with regular exercise and other healthy practices may help lower the low-density lipoprotein (LDL) in your blood.
Cholesterol is made in your liver and has many important functions. For example, it helps keep the walls of your cells flexible and is needed to make several hormones.
However, like anything in the body, too much cholesterol (or cholesterol in the wrong places) creates concerns.
Like fat, cholesterol does not dissolve in water. Instead, to move around the body, it depends on molecules called lipoproteins. These carry cholesterol, fat, and fat-soluble vitamins in your blood.
Different kinds of lipoproteins have different effects on health. For example, high levels of low-density lipoprotein (LDL) results in cholesterol deposits in blood vessel walls, which can lead to (1Trusted Source):
- clogged arteries
- heart attack
- kidney failure
In contrast, high-density lipoprotein (HDL) helps carry cholesterol away from vessel walls and helps prevent these conditions (2Trusted Source).
There are many natural ways to increase HDL (good) cholesterol and lower LDL (bad) cholesterol.
The liver produces as much cholesterol as your body needs. It packages cholesterol with fat in what’s called very low-density lipoproteins (VLDL).
As VLDL delivers fat to cells throughout the body, it changes into the more dense LDL, which carries cholesterol wherever it is needed.
The liver also releases HDL, which then carries unused cholesterol back to the liver. This process is called reverse cholesterol transport, and it protects against clogged arteries and other types of heart disease.
Some lipoproteins, especially LDL and VLDL, are prone to damage by free radicals in a process called oxidation. Oxidized LDL (oxLDL) and VLDL (oxVLDL) are even more harmful to heart health (3).
Although food companies often advertise products as being low in cholesterol, recent research has shown that dietary cholesterol actually has only a small influence on the amount of cholesterol in the body (4Trusted Source).
This is because the liver changes the amount of cholesterol it makes depending on how much you eat. When your body absorbs more cholesterol from your diet, it makes less in the liver.
Current guidelines by leading U.S. health organizations for lowering risk of heart disease no longer contain specific recommended levels for dietary cholesterol, including the:
- American Heart Association (AHA) (5Trusted Source)
- American College of Cardiology (ACC) (6Trusted Source)
- 2020–2025 Dietary Guidelines for Americans (DGA) (7Trusted Source)
Beginning in its 2015–2020 guidelines and continuing in the current 2020–2025 guidelines, the Dietary Guidelines Advisory Committee eliminated its previous recommended daily cholesterol limit in favor of a new focus on dietary patterns rather than macronutrients. Its recommendations are based on an extensive review of recent research (8Trusted Source).
The 2020 DGA recommends, for people 2 years old and over, to limit intake of saturated fat to less than 10% of calories per day. They also recommend replacing saturated fats with unsaturated fats, particularly polyunsaturated fats (8Trusted Source).
The guidelines do recommend moderating cholesterol consumption, but this is more to limit the saturated fat that often accompanies cholesterol in foods than to limit intake of cholesterol itself (9Trusted Source).
While dietary cholesterol may have little influence on your body’s cholesterol levels, other factors in your life may, such as:
- family history
- a sedentary lifestyle
- heavy alcohol consumption
Healthy lifestyle choices can help turn the tide by increasing the beneficial HDL and decreasing the harmful LDL. Read on to learn about natural ways to improve your cholesterol levels.
As opposed to saturated fats, unsaturated fats have at least one double chemical bond that changes the way your body uses them. Monounsaturated fats have only one double bond.
Some recommend a low fat diet for weight loss, but research is mixed on its effectiveness in controlling blood cholesterol.
One research report acknowledged that lower fat intake is an effective way to reduce blood cholesterol levels. However, researchers were concerned over potential negative effects of low fat diets, such as lowering HDL (good cholesterol) and increasing triglycerides (10Trusted Source).
In contrast, research has shown that a diet high in monounsaturated fats, such as the Mediterranean diet, helps reduce levels of harmful LDL and increase levels of healthy HDL (11Trusted Source).
Monounsaturated fats may also reduce the oxidation of cholesterol, according to research. Oxidized cholesterol can react with free radicals and contribute to clogged arteries. This can lead to atherosclerosis or heart disease (12)Trusted Source.
Overall, monounsaturated fats are healthy because they decrease harmful LDL cholesterol, increase good HDL cholesterol and reduce harmful oxidation (13Trusted Source, 14).
Here are a few great sources of monounsaturated fats. Some are also good sources of polyunsaturated fat:
- olive oil
- nuts, such as almonds, cashews, pecans, and macadamias
- canola oil
- nut butters
SUMMARYMonounsaturated fats like those in olive oil, canola oil, tree nuts, and avocados reduce LDL (bad) cholesterol, increase HDL (good) cholesterol, and reduce the oxidation that contributes to clogged arteries.
Polyunsaturated fats have multiple double bonds that make them behave differently in the body than saturated fats. Research shows that polyunsaturated fats reduce LDL (bad) cholesterol and decrease the risk of heart disease.
For example, one study replaced saturated fats in 115 adults’ diets with polyunsaturated fats for 8 weeks. By the end of the study, total and LDL (bad) cholesterol levels were reduced by about 10% (15Trusted Source).
Polyunsaturated fats also may reduce the risk of metabolic syndrome and type 2 diabetes.
Another study changed the diets of 4,220 adults, replacing 5% of their calories from carbohydrates with polyunsaturated fats. Their blood glucose and fasting insulin levels decreased, indicating a decreased risk of type 2 diabetes (16Trusted Source).
Omega-3 fatty acids are an especially heart-healthy type of polyunsaturated fat. They’re found in seafood and fish oil supplements. Especially high amounts occur in fatty fish like:
- deep sea tuna like bluefin or albacore
- shellfish (to a lesser degree), including shrimp
Other sources of omega-3s include seeds and tree nuts, but not peanuts.
SUMMARYAll polyunsaturated fats are heart-healthy and may reduce the risk of diabetes. Omega-3 fats are a type of polyunsaturated fat with extra heart benefits.
Trans fats are unsaturated fats that have been modified by a process called hydrogenation. This is done to make the unsaturated fats in vegetable oils more stable.
The resulting trans fats are not fully saturated and are called partially hydrogenated oils (PHOs).
They are solid at room temperature, which gives more texture than unsaturated liquid oils to products like spreads, pastries, and cookies. Their increased texture, as well as shelf stability, is what makes trans fats so attractive to food companies.
But partially hydrogenated trans fats are handled differently in the body than other fats, and not in a good way. Trans fats increase total cholesterol and LDL but decrease beneficial HDL (17Trusted Source).
The Food and Drug Administration (FDA) banned artificial PHOs, better known as trans fats, in processed foods in the United States as of 2018. The deadline was extended to January 1, 2020, to allow products already produced to work through distribution (18Trusted Source).
The World Health Organization (WHO) made a global call for the elimination of industrially produced trans fats from the global food supply by 2023 (19Trusted Source).
Foods that commonly contain trans fats include:
- margarine and shortening
- pastries and other baked goods
- some microwaveable popcorn
- fried fast foods
- some pizzas
- nondairy coffee creamer
A study of global health patterns found that consumption of excess trans fats, coupled with insufficient polyunsaturated fats and excess saturated fats, are a significant cause of coronary heart disease mortality globally (20Trusted Source).
In the United States, and in an increasing number of other countries, food companies are required to list the amount of trans fats in their products on nutrition labels.
However, these labels can be misleading, because companies are allowed to round down when the amount of trans fat per serving is less than 0.5 grams per serving. This means some foods contain trans fats even though their labels say “0 grams of trans fat per serving.” (21Trusted Source)
To avoid being misled, be sure to read the ingredients list in addition to the nutrition label. If a product contains “partially hydrogenated” oil, it contains trans fats and should be avoided.
SUMMARYFoods with “partially hydrogenated” oil in the ingredients contain trans fats and are harmful, even if the label claims the product has “0 grams of trans fat per serving.”
Soluble fiber is a group of different compounds in plants that dissolve in water and that humans can’t digest.
However, the beneficial bacteria that live in your intestines can digest soluble fiber. In fact, they require it for their own nutrition. Research has shown that these good bacteria, also called probiotics, can help reduce LDL levels (22Trusted Source).
A research review confirmed earlier findings that whole grains, which contain substantial amounts of fiber, decrease both total cholesterol and LDL cholesterol levels compared with control groups. The good news is that the whole grains were not shown to decrease levels of the good HDL cholesterol (23Trusted Source).
Soluble fiber can also help increase the cholesterol benefits of taking a statin medication.
One study published in 2014 suggested that, in a group of adults over 45, the use of statins combined with an increase in eating whole grain foods rich in fiber was associated with healthier lipoprotein profiles (24Trusted Source).
The benefits of soluble fibers stretches to many other diseases. A large review of several studies found high fiber intakes of both soluble and insoluble fiber reduced the risk of death over 17 years by nearly 15% (25Trusted Source).
Some of the best sources of soluble fiber include:
- oat cereals
- beans and lentils
- Brussels sprouts
Fiber supplements like psyllium are also safe and inexpensive sources of soluble fiber.
SUMMARYSoluble fiber nourishes healthy probiotic gut bacteria and helps removes LDL cholesterol from the body. Good sources include beans, peas, lentils, fruit, psyllium, and various whole grains, especially oats.
Exercise is a win-win for heart health. Not only does it improve physical fitness and help combat obesity, but it also reduces harmful LDL and increases beneficial HDL (26Trusted Source, 27Trusted Source).
The AHA advises that 150 minutes of moderate aerobic exercise a week is enough to lower cholesterol levels (28Trusted Source).
In one study, 12 weeks of combined aerobic and resistance exercise reduced the especially harmful oxidized LDL in 20 overweight women (29Trusted Source).
They exercised 3 days per week with 15 minutes each of aerobic activity including walking and jumping jacks, resistance-band training and low intensity Korean dance.
While even low intensity exercise like walking increases HDL, making your exercise longer and more intense increases the benefit (30Trusted Source).
Ideally, aerobic activity should raise the heart rate to about 75% of its maximum. Resistance training should be 50% of maximum effort.
Activity that elevates the heart rate to 85% of its maximum increases HDL and also decreases LDL. The longer the duration, the greater the effects (30Trusted Source).
Resistance exercise can decrease LDL even at moderate intensity. At maximum effort it also increases HDL. Increasing the number of sets or repetitions increases the benefit (30Trusted Source).
Some research disputes the effectiveness of moderate exercise at reducing cholesterol levels. One research review found that low to moderate aerobic exercise did not reduce the levels of LDL, except in several studies limited to specific populations (31).
Another study involving sedentary young women also found no change in lipid profiles after 8 weeks of different types of exercises (32Trusted Source.)
Researchers still recommended moderate exercise, especially for sedentary individuals, as it may help lower some specific-sized LDL particles called subfractions (33).
SUMMARYAny type of exercise may improve cholesterol levels and promote heart health. The longer and more intense the exercise, the greater the benefit.
Having excess weight or obesity can increase your risk of developing high cholesterol levels. Every 10 pounds of excess fat produces roughly 10 mg of cholesterol per day. The good news is that losing weight, if you have excess weight, can decrease your cholesterol levels (34).
Research shows that people who lost between 5–10% of their weight significantly reduced their total cholesterol and LDL cholesterol levels, as well as triglycerides. Those who lost more than 10% of their weight reduced cholesterol and triglyceride levels significantly more (35Trusted Source).
One study involving weight loss for women found that a diet high in healthy oils lowered both good and bad cholesterol. Women with overweight or obesity engaged in a 1-year behavioral weight loss program and randomly assigned to 1 of 3 diets:
- low fat and high carbohydrate
- low carbohydrate and high fat
- low carbohydrate and walnut-rich high fat
The walnut-rich diet affected cholesterol levels the most. It decreased LDL and increased HDL. The high fat, low carb group, whose diet emphasized monounsaturated fats, did not have the same beneficial cholesterol results as the walnut-rich diet group, whose diet emphasized polyunsaturated fatty acids (36Trusted Source).
Overall, weight loss has a double benefit on cholesterol by decreasing harmful LDL and increasing beneficial HDL. Work with your doctor closely to determine a nutrient-dense and sustainable weight loss plan.
SUMMARYWeight loss reduces total cholesterol, in part by decreasing the creation of new cholesterol in the liver. Weight loss also helps decrease LDL (bad) cholesterol and increase HDL (good) cholesterol.
Smoking increases the risk of heart disease in several ways. One of these is by changing how the body handles cholesterol.
The immune cells in smokers are unable to return cholesterol from vessel walls to the blood for transport to the liver. This damage is related to tobacco tar, rather than nicotine (37Trusted Source).
These dysfunctional immune cells may contribute to the faster development of clogged arteries in smokers.
Cigarettes contain a toxic chemical compound called acrolein that can be absorbed into the bloodstream through the lungs. Scientists believe it impairs how HDL in the body transports cholesterol and thereby increases LDL levels, which may lead to the development of heart disease (38).
Giving up smoking, if possible, can help reverse these harmful effects (39Trusted Source).
SUMMARYSmoking has been shown to increase LDL, decrease HDL, and hinder the body’s ability to transport cholesterol back to the liver to be stored or broken down. Quitting smoking can help reverse these effects.
Alcohol’s role in providing heart-protective benefits is one of today’s major health debates. Some research indicates that when used in moderation, alcoholic drinks can increase the good HDL cholesterol and reduce the risk of heart disease (40, 41Trusted Source).
Both the Centers for Disease Control and Prevention (CDC) and the AHA disagree. The AHA does not endorse drinking wine or any other alcoholic beverage specifically to lower your cholesterol or improve heart health. Both organizations say there is no credible research linking alcohol and improved heart health (42Trusted Source, 43Trusted Source).
The AHA acknowledges there may be a small rise of the good HDL cholesterol with moderate alcohol use, but it says exercise is a better way to achieve this benefit (43Trusted Source).
Some research recommends that alcohol consumption recommendations be reconsidered in light of its harmful effects on cardiovascular health, even in lower amounts (44).
What especially worries researchers about recommending moderate use of alcohol is the slippery slope down to misuse.
The AHA points out that triglycerides and total cholesterol levels increase with heavy alcohol intake. A recent study shows that heart damage may be occurring with heavy alcohol use even before symptoms appear (45Trusted Source, 46Trusted Source).
Although the question remains about whether or not alcohol can reduce heart disease risk, everyone agrees that too much alcohol harms the liver and increases the risk of dependence. It is important to consume alcohol only in moderation to achieve any potential cardiovascular benefit.
The CDC suggests you moderate drinking by consuming only 2 drinks per day for men or 1 drink per day for women, on days that you drink (47Trusted Source).
SUMMARYOn days you drink, 1–2 drinks per day may improve HDL cholesterol and reduce the risk of cardiovascular disease. However, heavier alcohol use increases heart disease risk and harms the liver.
Multiple types of supplements show promise for managing cholesterol.
Plant stanols and sterols are plant versions of cholesterol. Because they resemble cholesterol, they are absorbed from the diet like cholesterol.
However, because parts of their chemistry are different from human cholesterol, they do not contribute to clogged arteries.
Instead, they reduce cholesterol levels by competing with human cholesterol. When plant sterols are absorbed from the diet, this replaces the absorption of cholesterol.
Small amounts of plant stanols and sterols are naturally found in vegetable oils and are added to certain oils and butter substitutes.
A research review reported that clinical studies show that taking 1.5–3 grams of plant sterols/stanols daily can reduce LDL concentration by 7.5–12%. Researchers said taking it with a main meal twice per day allows for optimal cholesterol-lowering (48Trusted Source).
Although research has established the cholesterol-lowering benefit of plant stanols and sterols, it has not yet proved that they decrease the risk of heart disease. Numerous clinical trials have suggested that plant sterols supplements and enriched foods may lower heart disease risk, but hard data is still lacking (49Trusted Source).
SUMMARYPlant stanols and sterols in vegetable oil or margarines compete with cholesterol absorption and reduce LDL by up to 20%. They are not proven to reduce heart disease.
There is strong evidence that fish oil and soluble fiber improve cholesterol and promote heart health. Another supplement, coenzyme Q10, is showing promise in improving cholesterol, although its long-term benefits are not yet known.
Fish oil is rich in the omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
One study found that supplementing the diets of older adults who had high blood pressure and high cholesterol with fish oil-based Omega3Q10 reduced high blood pressure and both total cholesterol and LDL levels (50Trusted Source).
However, the AHA surprised the medical world in 2020 with the announcement that its international STRENGTH trial involving a medication made from fish oil failed to reduce the risk of cardiac events. The study involved 13,000 people who either had existing heart disease or were at risk of developing it (51Trusted Source).
Researchers acknowledged that while many people take fish oil to reduce risk of developing heart disease, at least with the product they used, this connection did not hold true. Researchers called for another trial to be conducted to resolve the issue (51Trusted Source).

Psyllium is a form of soluble fiber available as a supplement.
A research review of 28 studies found that psyllium fiber effectively lowers LDL cholesterol levels, potentially delaying the cardiovascular disease risk caused by clogged arteries in those with or without high cholesterol (52Trusted Source).
The FDA agrees, saying 7 grams of soluble fiber per day, taken from 10.2 grams of psyllium husk, helps reduce the risk of coronary artery disease based on psyllium’s ability to reduce cholesterol levels (53).
You can check out a selection of psyllium supplements online.
Coenzyme Q10 is a food chemical that helps cells produce energy. It is similar to a vitamin, except that the body can produce its own Q10, preventing deficiency.
Even if there is no deficiency, extra Q10 in the form of supplements may have benefits in some situations.
Several studies with a total of 409 participants found coenzyme Q10 supplements reduced total cholesterol. In these studies, LDL and HDL did not change (54Trusted Source).
A research review involving people with coronary artery disease showed that CoQ10 supplementation improved their lipid profiles by decreasing total cholesterol and increasing HDL levels. Triglycerides and LDL levels remained unaffected (55Trusted Source).
Another research review examining the effect of Q10 in treating cardiovascular and metabolic diseases. It found many encouraging results on the supplementation of COQ10 in different conditions but concluded that data was controversial and limited, and that more research is needed (56Trusted Source).
You can purchase coenzyme Q10 supplements online.
SUMMARYFish oil supplements and soluble fiber supplements like psyllium improve cholesterol and reduce the risk of heart disease. Coenzyme Q10 supplements reduce total cholesterol levels, but further research is needed on Q10’s role in reducing heart disease.
Cholesterol has important functions in the body, but can cause clogged arteries and heart disease when it gets out of control.
LDL is prone to free radical damage and contributes most to heart disease. In contrast, HDL protects against heart disease by carrying cholesterol away from vessel walls and back to the liver.
If your cholesterol is out of balance, lifestyle interventions are the first line of treatment.
Unsaturated fats, soluble fiber, and plant sterols and stanols can increase good HDL and decrease bad LDL. Exercise and weight loss can also help.
Eating trans fats and smoking are harmful and should be avoided.
The CDC recommends that you have your cholesterol levels checked every 5 years starting at age 20. Ask your doctor about any concerns you have. A simple blood draw, taken after an overnight fast, is all that’s required (57Trusted Source).
