Can Barley Unclog Arteries? What the Science Says

5 min read

According to a 2008 meta-analysis published by the American Journal of Cardiology, barley-derived beta-glucan significantly reduces total and LDL cholesterol. This heart-healthy grain's impressive fiber content raises an important question: can barley unclog arteries or does it simply help prevent blockages?

Quick Summary

Barley does not unclog existing arterial plaque, but its high soluble fiber (beta-glucan) content effectively lowers cholesterol, a major risk factor for heart disease.

Key Points

  • No Reversal: No single food, including barley, can literally "unclog" or reverse existing arterial plaque; medical treatment is required for blockages.

  • Lowers Cholesterol: The soluble fiber beta-glucan in barley significantly lowers LDL ("bad") and total cholesterol, a key risk factor for atherosclerosis.

  • Aids Prevention: By managing cholesterol and blood pressure, barley helps prevent the formation and progression of arterial plaque.

  • Whole Grain Preferred: Choose whole-grain (hulled) barley for maximum nutrients, though pearled barley still contains significant heart-healthy beta-glucan.

  • Part of a Healthy Diet: Barley should be consumed as part of a broader, heart-healthy diet rich in various whole foods, not as a standalone cure.

The Misleading Myth of "Unclogging" Arteries

It's a pervasive misconception that certain foods can reverse or "unclog" existing arterial plaque. Medical News Today clarifies that no specific food or treatment can reverse atherosclerosis, which is the buildup of fatty deposits in artery walls. This condition, sometimes called hardening of the arteries, is a chronic process that restricts blood flow. A heart-healthy diet, including barley, is a critical component of prevention and slowing the progression of the disease, but it is not a cure for existing blockages. For significant blockages, medical intervention is necessary.

The Science Behind Barley's Heart-Healthy Benefits

Barley's primary benefit for cardiovascular health lies in its high content of soluble fiber, specifically a type called beta-glucan. Research consistently shows that beta-glucan is highly effective at lowering cholesterol levels. The mechanism for this is well understood:

  • Binding Bile Acids: In the digestive system, beta-glucan forms a gel-like substance that binds to bile acids.
  • Increased Excretion: These bile acids, which are made from cholesterol in the liver, are then excreted from the body.
  • Lowering Blood Cholesterol: To replace the lost bile acids, the liver must pull more cholesterol from the bloodstream, thereby lowering overall circulating LDL ("bad") and total cholesterol levels.

Beyond cholesterol, barley has other protective effects. The Cleveland Clinic notes that some research suggests eating barley could lower blood pressure, another significant risk factor for heart disease. A diet rich in barley, along with other whole grains, can also improve blood sugar control, which is important for preventing complications like diabetes that contribute to atherosclerosis.

What is Atherosclerosis?

Atherosclerosis is a serious condition where plaques of cholesterol, fat, and other substances accumulate inside artery walls. Over time, these plaques can harden and narrow the arteries, making it difficult for blood to pass through. If a plaque ruptures, it can trigger a blood clot, leading to a heart attack or stroke. A low-fiber diet has been associated with more dangerous, unstable plaque features. Therefore, incorporating fiber-rich foods like barley is a proactive measure for prevention.

Simple Ways to Add Barley to Your Diet

  • Use hulled or pearled barley as a substitute for rice in risotto, pilaf, or side dishes.
  • Add barley to soups and stews to increase fiber content and create a hearty, satisfying texture.
  • Cook barley flakes as a warm breakfast porridge, similar to oatmeal, topped with fruit and nuts.
  • Toss cooked and cooled barley into salads for extra fiber and a chewy consistency.
  • Use barley flour in baking to increase the fiber content of breads and muffins.

Comparison of Barley to Other Heart-Healthy Grains

While barley offers significant benefits, it's helpful to compare its profile to other popular heart-healthy grains. It's important to remember that a varied diet is best, and both barley and oats, for example, have FDA-approved health claims for their cholesterol-lowering properties.

Feature Hulled Barley Pearled Barley Oats (Rolled/Steel Cut)
Processing Minimally processed (hull removed), whole grain. Polished to remove hull and some or all of the bran. Whole grain (hull removed).
Beta-Glucan Content Very high, found throughout the kernel. Still high, as beta-glucan is concentrated in the endosperm. High content, similar to barley.
Fiber Content Highest total fiber of all barley types. Lower total fiber than hulled, but still a good source. Excellent source of soluble fiber, particularly beta-glucan.
Cholesterol Benefits Excellent for lowering LDL and total cholesterol. Still very effective at lowering cholesterol. Excellent for lowering LDL and total cholesterol.
Texture Chewy, requires longer cooking time. Less chewy, cooks faster than hulled barley. Creamy texture, cooks quickly.

How to Maximize Barley's Heart Benefits

To get the most out of barley's health advantages, focus on two key areas: consuming enough beta-glucan and choosing the right form of the grain. To achieve the cholesterol-lowering effect, aim for at least 3 grams of barley beta-glucan per day. This can be achieved with a half cup of cooked hulled barley, or more depending on the specific product. Whole-grain hulled barley provides the most nutrients and fiber, but pearled barley is a good alternative and cooks more quickly. For those with celiac disease or gluten intolerance, barley is not a suitable option as it contains gluten. For others, combining barley with a variety of other heart-healthy foods like vegetables, legumes, and healthy fats is the best approach.

For more detailed information on heart-healthy eating, consult reputable health organizations such as the American Heart Association.

Conclusion

In summary, while the idea that barley can miraculously unclog arteries is a myth, its role in preventing and slowing the progression of heart disease is strongly supported by scientific evidence. The powerful soluble fiber, beta-glucan, effectively lowers cholesterol and helps manage other risk factors like high blood pressure and blood sugar. By incorporating whole-grain barley into a balanced, heart-healthy diet, you are taking a proactive step to support your cardiovascular system and reduce the risk of plaque buildup.

    • Question: Can barley reverse or cure clogged arteries?
    • Answer: No, barley cannot reverse or cure pre-existing plaque buildup in arteries. Its health benefits are focused on prevention and risk reduction, not reversal.
  • Question: How does barley's beta-glucan fiber help lower cholesterol?
    • Answer: The beta-glucan in barley binds to bile acids in the digestive system. The liver then pulls cholesterol from the bloodstream to produce more bile acids, which lowers total and LDL cholesterol.
  • Question: Is there a difference in health benefits between hulled and pearled barley?
    • Answer: Hulled barley is a whole grain with more overall fiber. However, pearled barley still contains significant amounts of heart-healthy beta-glucan in its endosperm, making both beneficial.
  • Question: How much barley do I need to eat to get the cholesterol-lowering effects?
    • Answer: The FDA and other health organizations suggest a daily intake of at least 3 grams of barley beta-glucan to achieve a cholesterol-lowering effect.
  • Question: Does barley help lower blood pressure?
    • Answer: Yes, some studies suggest that regular barley consumption can help lower blood pressure, which is another important factor in heart disease prevention.
  • Question: What are some easy ways to include barley in my diet?
    • Answer: Barley can be added to soups, stews, salads, or served as a side dish instead of rice. Barley flakes can also be used for breakfast porridge.
  • Question: Is barley an anti-inflammatory food?
    • Answer: Barley and its components have anti-inflammatory properties, and inflammation is a known contributor to the progression of atherosclerosis.
  • Question: Can people with gluten intolerance eat barley?
    • Answer: No, barley contains gluten and is not suitable for individuals with celiac disease or gluten sensitivity.
