The human heart pumps about 2,000 gallons of blood through the body daily, relying on healthy arteries to keep this vital flow moving. However, certain foods can contribute to plaque buildup in these arteries, potentially leading to serious health issues.
While many people know that some foods are “bad for the heart,” they might not know exactly which ones are bad or why. In this blog, I’ll explore some common foods that can harm your arteries without you realizing it.
Fried foods

Fried foods are often high in unhealthy fats that can clog arteries. They’re usually cooked in oils that are bad for heart health when heated to high temperatures. Eating fried foods regularly can lead to plaque buildup in the arteries. It’s better to choose baked or grilled options instead of fried ones.
Processed meats
Processed meats like bacon, sausages, and deli meats are often high in saturated fats and salt. These can contribute to high blood pressure and artery clogging. They also usually contain preservatives that may be harmful to heart health. Limiting processed meats and choosing lean, fresh meats is a healthier option.
Sugary drinks
Sodas and other sugary drinks can lead to weight gain and increase the risk of diabetes. These conditions are linked to a higher risk of heart disease and clogged arteries. The high sugar content can also cause inflammation in the body, which is bad for artery health. Water, unsweetened tea, or low-fat milk are better choices for everyday drinks.
Full-fat dairy products
Full-fat dairy products like whole milk, cheese, and butter are high in saturated fats. These fats can raise bad cholesterol levels and contribute to artery clogging. Consuming too much full-fat dairy can increase the risk of heart disease over time. Low-fat or fat-free dairy options are healthier choices for most people.
Red meat
Eating a lot of red meat, especially fatty cuts, can increase the risk of heart disease. Red meat is high in saturated fats, which can raise cholesterol levels. It can also lead to inflammation in the body, which is bad for artery health. Limiting red meat and choosing lean cuts when you do eat it is a better option.
Baked goods
Many baked goods like cookies, cakes, and pastries are high in sugar and unhealthy fats. They often contain trans fats, which are particularly bad for heart health. Regular consumption of these foods can contribute to weight gain and artery clogging. Homemade baked goods with healthier ingredients or fruit for dessert are better choices.
Fast food
Fast food meals are often high in calories, unhealthy fats, and salt. They can contribute to weight gain and high blood pressure, both risk factors for heart disease. Regular fast food consumption can lead to a buildup of plaque in the arteries over time. Preparing meals at home with fresh ingredients is a healthier alternative.
Margarine
Some types of margarine, especially stick margarine, can be high in trans fats. Trans fats are known to raise bad cholesterol and lower good cholesterol levels. This can lead to a buildup of plaque in the arteries and increase the risk of heart disease. Choosing olive oil or other healthy plant-based oils is better for heart health.
Alcohol (in excess)
While moderate alcohol consumption might have some health benefits, drinking too much is bad for the heart. Excessive alcohol can raise blood pressure and contribute to weight gain. It can also lead to high triglyceride levels, which can clog arteries. If you drink alcohol, it’s important to do so in moderation.

Canned soups
Many canned soups are very high in sodium, which can raise blood pressure. High blood pressure is a major risk factor for heart disease and clogged arteries. Some canned soups also contain unhealthy fats or added sugars. Making homemade soup or choosing low-sodium options is a healthier choice.
White bread
White bread and other refined grains can quickly raise blood sugar levels. This can lead to inflammation in the body, which is bad for artery health. Refined grains also lack the fiber that helps protect heart health. Choosing whole grain breads and cereals is a better option for heart health.
Ice cream
Ice cream is high in sugar and saturated fats, both of which can contribute to artery clogging. Regular consumption can lead to weight gain and increase the risk of heart disease. It can also cause spikes in blood sugar levels, which is bad for overall health. Enjoying ice cream as an occasional treat rather than a regular part of your diet is a better approach.
Pizza
Many pizzas are high in saturated fats from cheese and processed meats. They’re often also high in calories and can contribute to weight gain. Combining refined carbs, unhealthy fats, and salt can be bad for heart health. Making homemade pizza with healthier toppings or choosing veggie-based options can be a better choice.
Energy drinks
Energy drinks are often very high in sugar and caffeine. The high sugar content can lead to weight gain and inflammation in the body. Too much caffeine can raise blood pressure, which is terrible for artery health. Water or unsweetened tea are healthier choices for staying hydrated and energized.
Crackers
Many types of crackers are made with refined flour and unhealthy fats. They can quickly raise blood sugar levels and contribute to inflammation. Some crackers also contain trans fats, which are particularly bad for heart health. Choosing whole grain crackers or vegetables for snacking is a better option.
Frozen dinners
Many frozen dinners are high in sodium, which can raise blood pressure. They often contain unhealthy fats and refined carbohydrates. Some frozen meals are also high in calories, which can lead to weight gain. Preparing fresh meals at home or choosing low-sodium frozen options is healthier.
Coconut oil
Despite some health claims, coconut oil is very high in saturated fat. Too much saturated fat can raise harmful cholesterol levels and contribute to artery clogging. It’s often promoted as a health food, but it should be used in moderation. Other plant-based oils like olive oil are generally better choices for heart health.
Flavored yogurt
Many flavored yogurts are high in added sugars. Too much sugar can lead to weight gain and inflammation in the body. Some yogurts also contain unhealthy additives or artificial sweeteners. Choosing plain yogurt and adding your own fresh fruit is a healthier option.
Condiments
Many condiments, such as ketchup, barbecue sauce, and salad dressings, are high in sugar and salt. Regular use of these condiments can add a lot of hidden calories and sodium to your diet, which can contribute to weight gain and high blood pressure over time. Using herbs and spices or making your own dressings with healthier ingredients is a better choice.
Artificial sweeteners
While artificial sweeteners don’t contain calories, they may still have negative effects on heart health. Some studies suggest they can lead to weight gain and metabolic problems. They might also increase cravings for sweet foods, leading to overconsumption. Using small amounts of natural sweeteners or enjoying the natural sweetness of fruits is often a better option.
Cured meats
Cured meats like salami, prosciutto, and jerky are often high in salt and saturated fats. The curing process can create compounds that may be harmful to heart health. Regular consumption of cured meats has been linked to an increased risk of heart disease. Choosing fresh, lean meats or plant-based protein sources is generally healthier for the heart.
