Experts say oats, barley, farro, quinoa, bulgur, buckwheat, millet and amaranth can support heart health by supplying soluble fiber and other nutrients that help reduce LDL cholesterol and improve metabolic function.

Whole grains are gaining renewed attention as researchers and nutrition experts point to their potential role in lowering LDL cholesterol and supporting cardiovascular health.
A growing body of research has identified eight grains and grain-like seeds that may be especially useful for people seeking to improve cholesterol levels through diet: barley, oats, farro, quinoa, bulgur, buckwheat, millet and amaranth.
These foods contain soluble fiber, including beta-glucan, a type of fiber especially concentrated in oats and barley. In the digestive tract, soluble fiber can bind to LDL cholesterol and help remove it from the body before it is reabsorbed into the bloodstream.
The findings come as elevated cholesterol remains a major health concern for American adults and a key contributor to heart disease.
Oats remain among the most extensively studied grains for cholesterol management. A half-cup serving of uncooked rolled oats provides more than four grams of fiber. In one clinical trial, an oat-rich diet was linked to an average 10% reduction in LDL cholesterol after just two days.
Because of that evidence, oats are often recommended as a practical food-based option for people with borderline high cholesterol or those seeking to improve their lipid profile through dietary changes.
Barley may offer even higher levels of beta-glucan than oats. Its fiber content helps bind cholesterol directly, while also supporting the gut microbiome. Researchers have noted that barley’s complex fibers can feed beneficial bacteria in the digestive tract, which may contribute to reduced inflammation and improved lipid metabolism.
Whole barley provides the greatest nutritional value because it retains more of the bran and germ.
Quinoa, amaranth and buckwheat are often grouped with grains, though they are technically seeds. Each has drawn interest for possible cholesterol-related benefits.
Quinoa provides nearly six grams of fiber per half-cup serving and contains complete protein, meaning it supplies all essential amino acids. Regular quinoa consumption has been associated with lower total cholesterol and triglycerides.
Amaranth supplies fiber, iron and magnesium. Laboratory research suggests it may affect cholesterol through more than one pathway, while also contributing minerals important for metabolic and cardiovascular function.
Buckwheat is naturally gluten-free and contains rutin, an antioxidant linked in clinical research to improved blood vessel function and reduced arterial plaque buildup.
For those who tolerate gluten, bulgur and farro provide additional options.
Bulgur is made from wheat but undergoes relatively little processing, allowing it to retain much of the bran layer. That gives it a high fiber content, with nearly nine grams of fiber per half-cup serving. Its fiber density makes it especially useful for binding cholesterol in the digestive tract.
Farro, an ancient wheat grain with a firm texture, supplies plant-based protein and magnesium. Magnesium plays a role in cholesterol metabolism and blood sugar regulation, both of which are important for cardiovascular health.
Millet is another gluten-free grain that remains less common in Western diets but is widely eaten in parts of Asia and Africa. A review of millet-based foods found that regular consumption over several weeks may lower total and LDL cholesterol while modestly increasing HDL cholesterol.
Millet also provides B vitamins, iron and antioxidants. Its drought-resistant nature has made it valuable not only nutritionally but also agriculturally.
Nutrition experts say the benefits of whole grains are tied in part to what modern food processing removed.
For much of human history, grains were eaten in whole form. Industrial milling changed that by stripping away bran and germ to create refined white flour with a longer shelf life. That process removed much of the fiber, vitamins and minerals naturally present in grains.
As refined grains became dominant in modern diets, many people consumed fewer of the nutrients linked to heart and metabolic health.
Experts recommend replacing refined grains with whole grains in simple, consistent ways. Oatmeal or quinoa porridge can replace sugary breakfast cereals. Cooked farro, barley or quinoa can be added to salads. Bulgur or millet can be used as a base for grain bowls instead of white rice.
Consistency is important because cholesterol reduction depends on regular intake of soluble fiber over time.
“Grains are important because they are the seeds of grasses that provide essential nutrients like protein, fiber and B vitamins, which are vital for health,” said BrightU.AI’s Enoch. “However, milling and refining processes often remove the nutrient-rich germ and bran layers, diminishing their nutritional value. Understanding this helps us make informed choices about which grains to include in our diet for optimal health.”
Whole grains may support cholesterol management in several ways at once. They can bind cholesterol directly, feed beneficial gut bacteria, supply minerals needed for metabolism and help stabilize blood sugar.
They also remain inexpensive, widely available and easy to incorporate into everyday meals.
Researchers continue to study the specific effects of different grains, but the overall evidence supports a dietary shift away from refined grains and toward whole-food sources of fiber. For many people, adding oats, barley, quinoa, bulgur, buckwheat, millet, amaranth or farro may be a practical step toward improving cholesterol levels and supporting long-term heart health.
