Recently, my dad visited his doctor to review the results of his latest blood test. Unfortunately, the results weren’t what he had hoped for—the doctor informed him that his cholesterol levels were high. A previous test had already shown that he also had high blood pressure. Both high cholesterol and high blood pressure are risk factors for clogged arteries.
Arteries are the blood vessels that carry oxygen-rich blood from the heart to the rest of the body. When healthy, they are strong, flexible, and elastic. However, over time, they can become narrowed and blocked—a condition known as atherosclerosis. This is a serious health issue and a leading cause of cardiovascular diseases, including heart attacks, strokes, and peripheral vascular disease.
Presentation of Coronary Artery Disease
Carotid Arteries
When arteries supplying blood to the brain become blocked, the condition is known as carotid artery disease. The buildup of plaque narrows or obstructs the carotid arteries, which can lead to symptoms similar to those of a stroke. These symptoms may include difficulty breathing, sudden weakness, confusion, intense headaches, fainting, blurred vision, slurred speech, paralysis, difficulty walking, dizziness, unexplained falls, and loss of coordination or balance.
Coronary Arteries
When plaque builds up in the arteries that supply the heart, the condition is referred to as coronary heart disease (CHD). In this case, the narrowed arteries reduce blood flow to the heart muscle, leading to angina, or chest pain. Angina often feels like pressure or tightness in the chest but can also radiate to the jaw, neck, shoulders, arms, or back. Some people may even mistake it for indigestion. Emotional stress is a common trigger for angina. Additional symptoms of CHD may include irregular heartbeat and shortness of breath.
Renal Arteries
Blockage in the arteries leading to the kidneys is called renal artery disease, which can progress to chronic kidney disease. Initially, the condition may not show any symptoms. However, as it advances, kidney function may decline, leading to signs such as fatigue, nausea, poor appetite, difficulty concentrating, numbness or itchiness, and swelling in the hands or feet. It may eventually result in kidney failure and contribute to high blood pressure.
Peripheral Arteries
When arteries in the arms, legs, or pelvic area—known as peripheral arteries—become narrowed due to plaque buildup, it leads to peripheral arterial disease (PAD). This condition often causes pain, cramping, or numbness in the affected limbs. In some cases, it can also result in severe infections, especially when circulation is significantly reduced.
Understanding What Blocks Your Arteries
Atherosclerosis is commonly described as the hardening, thickening, and narrowing of the arteries. Healthy arteries are lined with a thin layer of endothelial cells that keep their inner walls smooth and help maintain proper blood flow. However, various harmful factors can damage these cells. These include platelet activity, elevated homocysteine levels, and free radicals from toxins or a lack of antioxidants.
Additionally, deficiencies in vitamin C and the amino acid homocysteine can break down a gel-like substance called the ground substance, which lies between cells and supports the structure of the endothelial barrier. When the endothelial lining is compromised, harmful materials begin to accumulate and form plaque. This plaque can include fats, calcium, toxic metals, cellular debris, and LDL (low-density lipoprotein) cholesterol. A clotting substance called fibrin also contributes to the blockage when it builds up in damaged arteries.
While the exact origin of artery clogging is not fully understood, research shows that atherosclerosis is a slow and complex process—often beginning in childhood and gradually worsening with age. Several factors have been identified as contributors to arterial damage, including smoking, high blood pressure, type 1 and type 2 diabetes, and insulin resistance.
Contributing Factors to Atherosclerosis
Other elements that may increase the risk of atherosclerosis include:
- Physical inactivity
- Obesity
- Chronic stress or type-A personality traits
- Exposure to heavy metals
- High triglyceride levels
- Chronic inflammation from autoimmune diseases, infections, lupus, or arthritis
- High levels of blood fats and cholesterol
- Genetics, in rare cases, may cause increased cholesterol production that promotes plaque buildup
Atherosclerosis can also be triggered by oxidative stress, especially when there is a deficiency in vitamin C or other antioxidants. Imbalances or deficiencies in essential nutrients such as magnesium, potassium, fiber, antioxidants, and methyl donors may also contribute to the development of this condition.
The Role of Diet
Unhealthy dietary habits are a major factor. Diets high in refined sugar, processed starches, and damaged fats (from overheated cooking oils) can accelerate atherosclerosis by increasing inflammation, oxidative stress, and cholesterol levels in the blood.
Nutritional Ways to Support Clean Arteries
Your doctor might recommend cholesterol-lowering medications, such as statins, or beta-blockers to help reduce blood pressure. These medications can slow down the progression of plaque buildup in the arteries—but they may come with significant side effects. Fortunately, there are also many well-researched natural foods that can support artery health and help prevent clogged arteries without the risks associated with pharmaceuticals.
1.Why Pomegranate Juice Is Good for Your Arteries
Pomegranate juice is rich in antioxidants and punicic acid, both of which are believed to reduce plaque buildup and help combat atherosclerosis. It also provides essential heart-healthy nutrients, including magnesium and selenium. A randomized, double-blind, parallel study published in the American Journal of Cardiology in 2009 found that individuals who drank 240 milliliters (ml) of pomegranate juice daily for up to 18 months experienced a slowed progression of carotid artery disease, especially among those at risk of coronary heart disease.
2.Boost Your Health with Fermented Cabbage
Kimchi, a popular Korean dish made from fermented cabbage and hot peppers, is known for its probiotic benefits and has been shown to slow the progression of atherosclerosis. A 2007 study published in the Journal of Agricultural and Food Chemistry identified an active compound in kimchi—called 3-94-hydroxy-3,5-dimethoxyphenyl—that helped prevent aortic atherosclerosis in rabbits fed a high-cholesterol diet. Additionally, fermented cabbage has demonstrated the ability to break down harmful chemicals such as bisphenol A and the insecticide chlorpyrifos.
3.Ground Flaxseed: A Nutritional Powerhouse
Flaxseed is another key food for supporting heart health. Ground flaxseed, rich in high fiber, helps maintain healthy arteries. It’s also an excellent source of alpha-linolenic acid (ALA), a type of omega-3 fatty acid that can reduce inflammation and lower blood pressure, both of which help prevent artery clogging.
A 1997 study published in the journal Atherosclerosis showed that flaxseed supplementation reduced the progression of aortic atherosclerosis by 46% in rabbits with high cholesterol. The researchers concluded that even modest amounts of flaxseed can effectively reduce hypercholesterolemic atherosclerosis.
For best results, it’s recommended to grind flaxseeds before consuming them, as ground flaxseed contains higher levels of omega-3 fatty acids. Whole or pre-ground flaxseed can lose their beneficial fats over time due to exposure to oxygen, causing the fats to break down and become rancid.
4.Cinnamon: A Natural Ally for Heart Health
Cinnamon may help reduce several risk factors linked to atherosclerosis and heart disease. A 2003 study published in Diabetes Care examined the effects of daily cinnamon intake—at doses of 1 gram, 3 grams, or 6 grams—on 60 people with type 2 diabetes over 40 days. The results showed that cinnamon lowered blood glucose, triglycerides, LDL cholesterol, and total cholesterol. Researchers concluded that cinnamon could be beneficial in reducing cardiovascular risk factors.
5.Incorporating Lemon Into Your Daily Routine
Adding lemon juice to your morning water is a simple and heart-healthy habit. Lemons are known to help lower blood cholesterol levels and protect arteries by reducing oxidative damage. They are also an excellent source of vitamin C, a powerful antioxidant. Studies show that high doses of vitamin C can strengthen arteries, decrease total cholesterol, boost HDL (good cholesterol), prevent blood clots by inhibiting platelet aggregation, and reduce inflammation.
6.Fire Up Your Heart Health with Cayenne Pepper
Spicy foods like cayenne pepper can also benefit your arteries. The active compound capsaicin found in cayenne pepper helps reduce LDL cholesterol levels in the blood. Additionally, cayenne pepper may lower the risk of stroke and heart attack while improving blood circulation. Interestingly, a 2009 study discovered that capsaicin could help prevent pulmonary and vascular complications caused by highly active antiretroviral therapy (HAART) with the HIV protease inhibitor ritonavir, which is known to accelerate atherosclerosis and pulmonary artery hypertension.
7.Adding Turmeric and Curcumin to Your Diet for Heart Health
Turmeric, a widely used spice in Indian and Ayurvedic cuisine, owes much of its health benefits to a powerful compound called curcumin. This primary polyphenol is well-known for its protective effects on the heart. Turmeric extract is believed to lower LDL cholesterol and reduce the buildup of plaque in the arteries.
A 2011 study published in Molecular Nutrition & Food Research found that turmeric was more effective than the cholesterol-lowering drug lovastatin at reducing cholesterol and suppressing early atherosclerotic lesions. Additionally, a 2006 study in mice suggested that curcumin may help prevent artery damage related to carotid artery blockage.
8.Ginger: A Natural Anti-Inflammatory for the Heart
Ginger possesses powerful anti-inflammatory and antioxidant properties. It contains heart-protective compounds such as shogaols and gingerols, which help prevent plaque buildup by lowering total cholesterol. A study published in the Journal of Nutrition in 2000 found that ginger extract reduced the size of aortic atherosclerotic lesions, as well as cholesterol, triglycerides, LDL-related fat peroxides, and LDL aggregation in the blood.
More Natural Solutions for Clearing Clogged Arteries
Other foods that can help prevent clogged arteries include asparagus, avocado, broccoli, chia seeds, fenugreek seeds, and coconut oil. Certain dietary supplements and nutrients may also support arterial health and help combat atherosclerosis. These include methyl donors such as vitamin B6, choline, folic acid, and vitamin B12, as well as antioxidants like vitamin C, vitamin E, lutein, zeaxanthin, grape seed extract, and pine bark extract.
Additional important nutrients include L-arginine, vitamin D, vitamin B3, fish oils, and coenzyme Q10 (CoQ10). Other beneficial supplements are magnesium, selenium, resveratrol, copper, chromium, and trimethylglycine.
Alongside nutrition, exercise plays a crucial role in maintaining cardiovascular health. Stress-reducing activities such as meditation, yoga, tai chi, and qigong are beneficial. Aerobic exercises like gardening, walking, or running also help combat atherosclerosis. Aim for about 30 minutes of moderate exercise most days of the week.
