Coronary heart disease stands as one of the world’s leading causes of death, accounting for a staggering 13% of all global fatalities according to the World Health Organization (WHO). The WHO has reported a concerning increase in cases since 2000, rising from an estimated 2.7 million deaths to nearly 9.7 million globally. This trend highlights the urgent need for preventative measures. Alarmingly, approximately 1 in 20 adults may unknowingly have coronary heart disease until it progresses to a critical stage, usually spurred on by chest pain. Insufficient physical activity, poor diets, and smoking, along with factors like genetics, age, and sex, drive this prevalence.
Coronary heart disease occurs when arteries become restricted due to plaque buildup within the arterial walls. This narrowing impedes blood flow to and from the heart, depriving it of vital oxygen-rich blood. The cause behind this build-up is often an increase in low-density cholesterol (LDL), commonly known as “bad” cholesterol, which contributes significantly to atherosclerosis and other cardiovascular diseases.
As fatty deposits accumulate on arterial walls, they lead to atherosclerosis, which is a hardening and clogging of the arteries that severely compromises their function. Managing arterial health has never been more imperative, and strategies for doing so may surprisingly begin with readily accessible spices and herbs available at most convenience stores. These spices and herbs offer a potential avenue for intervention against this rapidly growing global threat warranting urgent action globally.
Top 10 Spices & Herbs to Bolster Arterial Health
For centuries herbs and spices have played a role in traditional medicine, for treating myriads of health issues. People have also praised them for encouraging artery cleansing and reducing plaque buildup. Beyond just flavoring food and adding some heat to dishes, spices and herbs can bolster your arterial health. Here are 10 spices and herbs to use in your dishes to not only better your flavor but encourage and support arterial health.
1. Garlic
Garlic is a bulbous flowering plant that is in the same family as onions, leaks, chives and shallots. People commonly use garlic in culinary dishes globally and have also used it as traditional medicine for millennia. They consider garlic to offer numerous health benefits, such as boosting the immune system and lowering high blood pressure and LDL cholesterol levels. As far back as in ancient Indian texts, there has been some speculation about the arterial health and cardiovascular benefits of garlic. Scientists first began conducting studies on garlic for arterial health and cardiovascular benefits in the 1950.
Why garlic works for Arterial Health
Currently, scientists have published 1000’s of studies on research conducted on both animals and humans. Both in vivo and in vitro, to isolate and pinpoint garlic’s active ingredients and evaluate efficacy. Garlic’s active compound allicin has been speculated to have anti-inflammatory and relaxing effects on the arterial muscles, widening the blood vessels.
Benefits of Garlic on Arterial Health
Garlic’s active compounds, most notably allicin, hold considerable promise regarding arterial health benefits. The mechanism by which allicin appears to show its effects involves relaxing blood vessels, leading to a reduction in elevated blood pressure. Furthermore, research shows that garlic lowers LDL cholesterol levels, which helps reduce plaque buildup within arterial walls, a major risk factor in cardiovascular disease progression.
Beyond these core mechanisms, emerging research suggests potential benefits related to improved regulation of blood flow, blood clots and even antioxidant effects that could protect against oxidative stress, another contributor to arterial damage. Some studies have also indicated a possible role for garlic in reducing platelet aggregation, essentially making the blood less prone to clotting which is paramount to stroke prevention.
Criticism and further research
However, studies in this field remain subtle and complex, and ongoing research continues to face challenges with critiques surrounding garlic’s application and testing. A significant challenge lies in the lack of standardization across preparations, hindering efforts to conduct controlled, directly comparable studies. This often results in data that can be difficult to interpret. Even trials employing similar controls sometimes yield varied results. While some in vitro and animal studies have demonstrated positive effects, translating these findings to human efficacy remains an open question, warranting further investigation into garlic’s potential role in arterial health management.
2. Turmeric
Turmeric (Curcuma longa) is a perennial plant native to South Asia known for its vibrant yellow-orange color. It’s an aromatic spice commonly added to curries and other south Asian dishes. For centuries traditional Ayurvedic and Chinese medicine have recognized its potential health benefits, from aiding digestion to offering anti-inflammatory support. There has been a particular surge in research on these aforementioned benefits, including a focus on turmeric’s benefits in arterial health.
Why Turmeric works for Arterial Health
The active compound of turmeric, curcumin, is of particular interest due to its antioxidative and anti-inflammatory properties and its potential impact on cardiovascular function. A significant number of studies suggest it can help mitigate factors contributing to heart problems. It helps lower oxidative stress, the build-up of damaging molecules, and how cells stick to blood vessels.
Curcumin has also shown to have positive effects on signaling pathways in heart tissue, potentially assisting in improving heart function, even after trauma or injury to the heart. Recent work even hints at curcumin’s ability to cardiac remodeling, a process potentially impacting blood pressure control and collagen buildup.
Benefits of Turmeric on Arterial Health
Turmeric’s potential benefits to arterial health extend to vasodilation, allowing vessels to relax and improve blood flow. The active ingredient in turmeric, curcumin, is vital in preventing hardening of the arterial walls, which eventually leads to the development of atherosclerosis. Researchers have mounted evidence suggesting turmeric might actively help inhibit this process by reducing inflammation and damage within arterial walls. By reducing these factors, turmeric could potentially mitigate major threats to arterial health, namely plaque build-up and blood clots.
Criticism and further research
The data collected by researchers seems promising, however, the data is still faced with limitations. The majority of current research comes from in vitro studies or animal models. Researchers need to fully investigate robust clinical trials to truly refine our understanding of turmeric’s impact on arterial health and establish optimal dosages for cardiovascular benefit.
3.Cayenne Pepper / Chili Peppers (Capsicum)
Capsicum annum, more commonly known as chili pepper, red pepper, sweet pepper, jalapeño, cayenne, or bell pepper is a staple ingredient in a variety of cuisines worldwide. Known for its active compound, capsaicin, that makes these fruits so spicy and adds robust flavor to dishes, this family of flowering fruits has also been revered for their arterial health benefits. Emerging research increasingly highlights the potential cardiovascular benefits capsaicin potentially delivers. Research shows that people who consume chili peppers or any other fruit containing capsaicin tend to live longer than those who did not.
Why Capsicum works for Arterial Health
Capsaicin, the active ingredient of capsicum-rich fruits, has several benefits that aid the protection and maintenance of arterial health. Studies consistently show it can help prevent blood clots from forming which contributes to lower blood pressure, alongside improvements in cholesterol levels. Researchers observed that capsaicin reduced plaque buildup in arterial walls, which is the leading cause of atherosclerosis, but this result appeared in mice, rats, and guinea pigs.
Importantly, capsaicin influences how arteries work by changing gene expression, inhibiting genes that cause arteries to constrict. This is especially important considering how common metabolic syndrome has become, a condition that inactivity and overeating worsen, and given its established link to increased cardiovascular risk.
Benefits of Capsicum on Arterial Health
Capsaicin’s increase of life expectancy in those who consumed it as opposed to those who do not have garnered increased interest into capsaicin’s mechanism and biological operations. Early studies suggested capsaicin directly helped prevent metabolic syndrome. Research shows that capsicum lowers LDL cholesterol levels, preventing plaque build-up in the arterial wall and reduces hypertension, both major causes of poor arterial health.
Criticism and further research
Although initial findings and observations suggest that consuming capsaicin may improve cardio-metabolic outcomes, researchers still need to conduct further studies. Clinical trials directly testing capsaicin’s impact on blood sugar or cholesterol have provided some unclear answers on how capsaicin influences arterial health and cardiovascular risk. Although a diet rich in chili peppers may support overall wellness, people shouldn’t rely on it alone to manage heart disease or arterial health.
