Learn About Foods That Lower Cholesterol Naturally

Understanding Cholesterol and Why It Matters

Cholesterol is a waxy substance that your body produces naturally and that you also consume through food. While your body needs some cholesterol to function properly, having too much can build up in your arteries and increase your risk of heart disease and stroke. According to the Centers for Disease Control and Prevention, about 1 in 5 American adults have high cholesterol, yet only about half of those with high cholesterol are being treated.

Your blood carries two main types of cholesterol: LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL is often called "bad" cholesterol because high levels can lead to plaque buildup in arteries. HDL is called "good" cholesterol because it helps remove LDL from your bloodstream. The goal is to keep LDL levels low and HDL levels high. A total cholesterol reading under 200 mg/dL is considered desirable, according to the American Heart Association.

Many people discover they have high cholesterol only through blood tests, as there are typically no symptoms. This is why regular health screenings matter. The good news is that you can influence your cholesterol levels through the foods you eat, along with physical activity and other lifestyle choices. Diet changes can reduce LDL cholesterol by up to 30 percent, according to research published in the Journal of the American College of Cardiology.

Practical Takeaway: Understanding your cholesterol numbers is the first step. Ask your healthcare provider about your cholesterol levels at your next check-up so you know where you stand and can make informed choices about your diet.

Soluble Fiber Foods That Help Lower Cholesterol

Soluble fiber is one of the most effective dietary tools for lowering cholesterol naturally. This type of fiber dissolves in water to form a gel-like substance in your digestive system. As it moves through your stomach and intestines, soluble fiber binds to cholesterol particles and helps your body eliminate them before they enter your bloodstream. Research shows that eating 10 grams of soluble fiber per day can reduce LDL cholesterol by approximately 3.8 percent.

Oats are among the most well-known sources of soluble fiber. One cup of cooked oatmeal contains about 4 grams of soluble fiber. The FDA recognizes oats as heart-healthy, and studies have shown that eating three grams of beta-glucan (a type of soluble fiber found in oats) daily can help reduce cholesterol levels. A simple breakfast of plain oatmeal topped with berries and a small amount of honey provides a satisfying meal that works toward your cholesterol goals.

Other excellent sources of soluble fiber include:

• Barley and other whole grains
• Beans and legumes (black beans, kidney beans, lentils)
• Apples and pears with the skin on
• Citrus fruits like oranges and grapefruits
• Sweet potatoes
• Chia seeds and ground flaxseeds

A practical approach is to gradually increase your soluble fiber intake rather than making sudden large changes. Start by adding one new fiber-rich food to your diet each week, and drink plenty of water to help the fiber work effectively in your system. For example, you might swap your regular toast for whole grain toast one day, add beans to your salad another day, and snack on an apple with almond butter on a third day.

Practical Takeaway: Aim to include at least one soluble fiber food with each meal. Start your day with oatmeal, have legumes in your lunch salad, and eat fruit as a snack to reach recommended fiber levels throughout the day.

Healthy Fats That Improve Cholesterol Levels

Not all fats are harmful to your cholesterol levels. In fact, certain types of fat can actually help raise HDL (good) cholesterol while lowering LDL (bad) cholesterol. The key is understanding the difference between saturated fats, trans fats, and unsaturated fats. Saturated fats and trans fats can increase LDL cholesterol, while monounsaturated and polyunsaturated fats can help lower it.

Fatty fish are rich in omega-3 fatty acids, a type of polyunsaturated fat with documented heart-health benefits. The American Heart Association recommends eating two servings of fatty fish per week, where each serving is about 3.5 ounces. Salmon, mackerel, sardines, trout, and herring are excellent choices. A study published in Nutrition Reviews found that consuming omega-3 fatty acids can help lower triglycerides (another type of blood fat) and may help prevent blood clots.

Plant-based sources of healthy fats include:

• Olive oil (use 1-2 tablespoons per serving)
• Avocados (about half an avocado is one serving)
• Nuts and seeds (almonds, walnuts, sunflower seeds)
• Nut butters (almond butter, peanut butter in moderation)
• Vegetable oils like canola and sunflower oil

A Mediterranean-style diet, which emphasizes these healthy fats along with vegetables and whole grains, has been extensively studied. The PREDIMED study, which followed over 7,000 people for five years, found that those following a Mediterranean diet had a 30 percent lower risk of heart disease compared to those on a low-fat diet. You can follow this pattern by using olive oil in salad dressings, choosing fish several times weekly, and snacking on a small handful of nuts.

Practical Takeaway: Replace saturated fats with healthy unsaturated fats by swapping butter for olive oil, choosing fish instead of fatty meat twice weekly, and enjoying a small portion of nuts or avocado as a snack.

Plant-Based Foods and Cholesterol Reduction

Plant-based foods offer multiple pathways to lower cholesterol naturally. They contain fiber, healthy fats, and other compounds that work together to reduce LDL cholesterol levels. You don't need to become fully vegetarian to benefit—simply adding more plant foods to your plate makes a measurable difference. A meta-analysis of 30 studies found that vegetarians have LDL cholesterol levels about 16 percent lower than non-vegetarians.

Nuts are particularly powerful for cholesterol management. Almonds, walnuts, and pistachios contain plant sterols (also called phytosterols), compounds that actively block cholesterol absorption in your intestines. Consuming about 1.5 to 2 ounces of nuts daily—roughly a small handful—has been shown to reduce LDL cholesterol by up to 5 percent. Walnuts are especially rich in omega-3 fatty acids, with just one ounce providing 2.5 grams.

Whole grains deserve special attention because they contain multiple cholesterol-lowering compounds. Brown rice, quinoa, oats, barley, and whole wheat have more fiber and beneficial compounds than refined grains. When you choose whole grains over refined white bread and white rice, you're choosing foods with three times the fiber in many cases. Studies show that eating three servings of whole grains daily is associated with a 26 percent lower risk of heart disease.

Other plant foods with cholesterol-lowering properties include:

• Soy products (tofu and edamame contain plant protein and may lower LDL cholesterol)
• Garlic (contains allicin, which has mild cholesterol-lowering effects)
• Green tea (contains catechins, antioxidants that may help with cholesterol)
• Herbs and spices like cinnamon, turmeric, and oregano
• Dark leafy greens (spinach, kale, and collard greens)
