For many of us, coffee is an essential part of our daily routine. We rely on it to wake us up in the morning, boost our energy levels, and get us through those long days at work. However, there’s been a lot of debate about the potential health risks associated with coffee consumption, particularly when it comes to heart health. One of the most common concerns is whether coffee can cause plaque in arteries, leading to conditions like atherosclerosis and heart disease. In this article, we’ll delve into the latest research and explore the relationship between coffee and artery plaque.
What is Artery Plaque?
Before we dive into the world of coffee and artery plaque, it’s essential to understand what artery plaque is and how it forms. Artery plaque, also known as atherosclerosis, is a condition where a sticky substance called plaque builds up inside the arteries, causing them to narrow and harden. This plaque is made up of various substances, including:
- Cholesterol
- Fatty compounds
- Calcium
- Inflammatory cells
Over time, the buildup of plaque can lead to a range of health problems, including:
- High blood pressure
- Heart disease
- Stroke
- Peripheral artery disease
The Role of Lifestyle Factors in Artery Plaque Formation
While genetics can play a role in the development of artery plaque, lifestyle factors are often the primary contributors. Some of the most significant lifestyle factors that can increase the risk of artery plaque formation include:
- Smoking
- High blood pressure
- High cholesterol
- Diabetes
- Obesity
- Lack of exercise
- Poor diet
Coffee and Artery Plaque: The Research
So, what does the research say about coffee and artery plaque? The answer is not a simple one. Some studies have suggested that moderate coffee consumption may actually have a positive effect on heart health, while others have raised concerns about the potential risks.
A 2017 study published in the journal Heart found that moderate coffee consumption (defined as 3-4 cups per day) was associated with a lower risk of stroke, type 2 diabetes, and certain types of cancer. However, the study also noted that high levels of coffee consumption (more than 4 cups per day) may increase the risk of heart disease.
Another study published in the Journal of the American Heart Association in 2018 found that coffee consumption was not associated with an increased risk of artery plaque formation in a group of over 25,000 adults. In fact, the study suggested that moderate coffee consumption may even have a protective effect against artery plaque.
However, not all studies have been so positive. A 2019 study published in the Journal of Agricultural and Food Chemistry found that a compound called cafestol, which is found in unfiltered coffee, may increase the levels of low-density lipoprotein (LDL) cholesterol in the blood. High levels of LDL cholesterol are a known risk factor for artery plaque formation.
The Impact of Coffee on Blood Pressure and Heart Rate
One of the primary concerns about coffee consumption is its potential impact on blood pressure and heart rate. Caffeine, the stimulant found in coffee, can cause blood pressure to rise and heart rate to increase. This can be a problem for people who already have high blood pressure or other heart health issues.
However, research has shown that moderate coffee consumption is unlikely to have a significant impact on blood pressure and heart rate in healthy adults. A 2018 study published in the Journal of Human Hypertension found that moderate coffee consumption did not increase blood pressure or heart rate in a group of healthy adults.
Other Factors to Consider
While the research on coffee and artery plaque is complex, there are other factors to consider when it comes to the potential health risks of coffee consumption. For example:
- Added sugars and creamers: Many coffee drinks are high in added sugars and creamers, which can greatly increase calorie intake and contribute to weight gain and other health problems.
- Caffeine sensitivity: Some people are more sensitive to the effects of caffeine than others. If you’re sensitive to caffeine, you may experience jitters, anxiety, and an increase in heart rate and blood pressure.
- Individual tolerance: Regular coffee consumption can lead to individual tolerance, which means that you may need to consume more coffee to feel the same effects. This can increase the risk of negative side effects.
Who Should Avoid Coffee or Limit Consumption
While moderate coffee consumption is unlikely to cause significant harm in healthy adults, there are certain groups of people who should avoid coffee or limit their consumption. These include:
- Pregnant or breastfeeding women: High levels of caffeine can increase the risk of miscarriage and other pregnancy complications.
- Children and adolescents: Caffeine can have negative effects on developing brains and bodies.
- People with high blood pressure or heart disease: Caffeine can increase blood pressure and heart rate, which can exacerbate existing heart health issues.
- People with anxiety or insomnia: Caffeine can worsen anxiety and insomnia symptoms.
Conclusion
The relationship between coffee and artery plaque is complex, and more research is needed to fully understand the potential health risks and benefits. However, based on the current evidence, it appears that moderate coffee consumption is unlikely to cause significant harm in healthy adults.
If you’re a coffee lover, there’s no need to quit cold turkey. However, it’s essential to be mindful of your overall lifestyle and diet. By making healthy choices, such as exercising regularly, eating a balanced diet, and managing stress, you can reduce your risk of artery plaque formation and other heart health issues.
Ultimately, the key is to be aware of the potential risks and benefits of coffee consumption and to make informed choices about your lifestyle and diet. By doing so, you can enjoy your daily cup of coffee while also protecting your heart health.

What is artery plaque and how does it affect the body?
Artery plaque, also known as atherosclerosis, is a condition where a buildup of fatty deposits, cholesterol, and other substances forms on the inner walls of the arteries. This buildup can cause the arteries to narrow and harden, restricting blood flow to vital organs and tissues. If left untreated, artery plaque can lead to serious health complications, including heart attacks, strokes, and peripheral artery disease.
The formation of artery plaque is a complex process that involves a combination of genetic, lifestyle, and environmental factors. High levels of low-density lipoprotein (LDL) cholesterol, high blood pressure, smoking, and a diet high in saturated fats and cholesterol can all contribute to the development of artery plaque. Additionally, age, family history, and certain medical conditions, such as diabetes, can also increase the risk of developing artery plaque.
What is the relationship between coffee consumption and artery plaque?
Research on the relationship between coffee consumption and artery plaque has yielded mixed results. Some studies have suggested that moderate coffee consumption may actually help to reduce the risk of developing artery plaque, while others have found no significant association. A few studies have even suggested that high levels of coffee consumption may increase the risk of artery plaque, although these findings are not consistent across all studies.
The exact mechanisms by which coffee consumption may affect artery plaque are not fully understood. However, it is thought that the antioxidants and polyphenols present in coffee may help to protect against oxidative stress and inflammation, which are both key factors in the development of artery plaque. Additionally, moderate coffee consumption may also help to improve blood flow and lower blood pressure, both of which can help to reduce the risk of artery plaque.
How much coffee is safe to consume in relation to artery plaque?
The safe amount of coffee to consume in relation to artery plaque is not well established. However, most studies suggest that moderate coffee consumption, defined as 3-4 cups per day, is unlikely to have a significant impact on the risk of developing artery plaque. In fact, some studies have suggested that moderate coffee consumption may even have a protective effect against artery plaque.
It is worth noting, however, that individual tolerance to coffee and caffeine can vary greatly. Some people may experience adverse effects, such as increased heart rate and blood pressure, at much lower levels of coffee consumption. Additionally, adding large amounts of sugar, cream, or syrup to coffee can greatly increase calorie intake, which can contribute to weight gain and increase the risk of artery plaque.
Can coffee consumption increase the risk of heart disease?
The relationship between coffee consumption and heart disease is complex and not fully understood. Some studies have suggested that high levels of coffee consumption may increase the risk of heart disease, particularly in people who are sensitive to the effects of caffeine. However, other studies have found no significant association between coffee consumption and heart disease.
It is thought that the potential cardiovascular risks of coffee consumption may be due to the stimulatory effects of caffeine, which can increase heart rate and blood pressure. However, moderate coffee consumption is unlikely to have a significant impact on the risk of heart disease in most people. In fact, some studies have suggested that moderate coffee consumption may even have a protective effect against certain types of heart disease, such as stroke and type 2 diabetes.
Are there any specific types of coffee that are better or worse for artery health?
The type of coffee consumed may have an impact on artery health. Unfiltered coffee, such as French press or Turkish coffee, contains higher levels of cafestol and kahweol, which are compounds that may increase levels of LDL cholesterol. On the other hand, filtered coffee, such as drip coffee, contains lower levels of these compounds and may be a better choice for people concerned about artery health.
Additionally, coffee drinks that are high in sugar, cream, and syrup can greatly increase calorie intake, which can contribute to weight gain and increase the risk of artery plaque. In contrast, black coffee or coffee consumed with a small amount of low-fat milk or sugar may be a healthier choice.
Can coffee consumption interact with medications used to treat artery plaque?
Coffee consumption may interact with certain medications used to treat artery plaque. For example, caffeine can interact with certain blood thinners, such as warfarin, and decrease their effectiveness. Additionally, caffeine can also interact with certain medications used to treat high blood pressure, such as beta blockers, and increase blood pressure.
It is essential for people taking medications for artery plaque to consult with their healthcare provider about safe levels of coffee consumption. Additionally, people taking medications should be aware of the potential for interactions and monitor their blood pressure and other health parameters closely.
What are the key takeaways for coffee lovers concerned about artery plaque?
The key takeaways for coffee lovers concerned about artery plaque are to consume coffee in moderation, defined as 3-4 cups per day, and to be mindful of overall lifestyle habits. Additionally, choosing filtered coffee and avoiding large amounts of sugar, cream, and syrup can help to minimize potential negative effects on artery health.
It is also essential to maintain a healthy lifestyle, including a balanced diet, regular exercise, and stress management, to reduce the risk of artery plaque. By making informed choices about coffee consumption and overall lifestyle habits, coffee lovers can enjoy their daily cup while minimizing potential risks to artery health.
