Consuming fiber-rich foods is an effective way to help lower high cholesterol levels. Fiber, especially soluble fiber, can bind to cholesterol in your digestive system and remove it from your body before it reaches your bloodstream.
By making a few simple dietary changes to increase your daily fiber intake, you may be able to reduce your cholesterol and improve your heart health.
Understanding Soluble and Insoluble Fiber
Two main types of dietary fiber exist: soluble and insoluble. Both are important for health, but soluble fiber might be particularly helpful for lowering LDL (bad) cholesterol levels.
Foods with soluble fiber dissolve in water to form a material similar to gel in your digestive tract. This helps trap cholesterol and remove it from your body rather than allowing it to enter your bloodstream. Sources of soluble fiber include apples, oats, beans, lentils, pears, and psyllium husk.
Meanwhile, insoluble fiber does not dissolve in water, which helps with regular bowel movements and reduces the chances of constipation. Whole grains, vegetables, nuts, and seeds are great sources of insoluble fiber. Be sure to incorporate both forms of fiber into your diet.
Add Oats to Your Breakfast
One of the easiest ways to increase your soluble fiber intake is to enjoy a bowl of oatmeal for breakfast. Oats contain a special form of soluble fiber dubbed beta-glucan, which is particularly effective at lowering LDL cholesterol levels. The beta-glucan in oats forms a thick gel that binds to cholesterol-rich bile acids in your digestive tract, so they pass out of your body rather than being absorbed.
Aim to eat at least 1⁄2 cup of cooked oatmeal, which gives you about 4 grams of fiber daily. You can incorporate even more fiber by adding fresh fruit, such as bananas or berries, to your oatmeal. Overnight oats soaked in milk are another simple way to enjoy oats while saving time in the morning.
Load Up On Beans and Lentils
Beans and lentils also pack a powerful punch when it comes to soluble fiber. Black beans, kidney beans, pinto beans, garbanzo beans, navy beans, and lentils are all brilliant options. Try substituting beans or lentils for meat in your favorite recipes, such as chili, tacos, burgers, and pasta.
One cup of cooked beans provides a whopping 9-12 grams of fiber, making it easy to reach the recommended 25 grams of fiber per day. The viscous fiber in beans and lentils helps restrict the absorption of cholesterol into your bloodstream. Beans are also rich in antioxidants and phytochemicals that benefit heart health.
Snack On Fruit and Nuts
In addition to oats and beans, snacking on fruit and nuts throughout your day enables you to increase fiber intake effortlessly. Most fruits contain soluble pectin fiber, with apples and pears being top choices, thanks to about 5 grams of fiber per medium-sized fruit. Berries, oranges, and bananas also contribute valuable fiber.
Almonds and other nuts provide insoluble fiber that promotes healthy digestion. A small handful of nuts can provide 2-3 grams of fiber. The healthy fats in nuts have also been shown in studies to improve cholesterol levels when eaten in moderation.
Add Ground Flaxseed to Recipes
Flaxseed provides soluble fiber along with heart-healthy omega-3 fatty acids called ALA. However, your body cannot access these nutrients from whole flaxseeds. Use a coffee grinder to grind flaxseed into a fine powder, then stir a tablespoon into oatmeal, smoothies, baked goods, and other foods.
The ground flaxseed gel that forms during digestion can help eliminate cholesterol-rich bile acids. It’s best to consume flaxseed in ground form rather than flaxseed oil since the oil does not provide fiber.
Cook With Avocados
Avocados’ creamy, rich texture makes them perfect for increasing soluble fiber without compromising taste or nutrition. Just half of a medium avocado provides 5 grams of fiber in addition to ample monounsaturated fats linked with better cholesterol levels.
Mash some avocado to serve on toast, dice it into salads, or add it to smoothies. Using avocado instead of cheese, meat, or other ingredients higher in saturated fat can further benefit cholesterol.
Up Your Veggie Intake
In addition to the specific foods mentioned, increasing your overall vegetable and fruit consumption significantly boosts fiber intake. Shoot for getting the recommended 5-9 servings of fruits and vegetables daily. Not only are veggies naturally low in fat and calories, but they contain both soluble and insoluble fiber that supports cardiovascular wellness.
Some of the best picks are broccoli, carrots, artichokes, green peas, Brussels sprouts, and sweet potatoes. When grocery shopping, make certain that a minimum of half your cart contains a rainbow of produce. Pre-wash and pre-cut your veggies for quick and convenient snacking.
Add Fiber Supplements If Needed
If making dietary changes still leaves your fiber intake below the 25 grams per day minimum recommendation, consider adding a fiber supplement such as psyllium husk. Psyllium is a soluble fiber supplement derived from seeds that can lower total and LDL cholesterol levels. It works by absorbing water in your stomach to form a thick gel that traps bile acids.
Studies suggest psyllium husk may enhance the effects of cholesterol-lowering medications. However, fiber supplements cannot replace high-fiber foods that provide vitamins, minerals, antioxidants, and other beneficial plant compounds. Speak to your doctor to determine if adding a fiber supplement may benefit your health status and needs.
