Consuming diets rich in ultra-processed foods, added sugars, and unhealthy fats can heighten the risk of heart disease. However, making dietary adjustments can yield a positive impact on heart health, even for individuals already facing heart disease challenges. The heart, a remarkable and intricate organ, tirelessly functions to ensure a steady flow of oxygen-rich blood throughout the body. It operates as a crucial component of the cardiovascular system, which encompasses not only the heart but also the arteries, veins, and capillaries that facilitate blood circulation.

Studies indicate that diet may serve as the most significant preventive measure against heart disease-related fatalities, which contribute to approximately one-third of deaths worldwide. Adopting a heart-healthy eating pattern can greatly diminish the likelihood of developing heart disease, as well as reduce the risk of death associated with it. This article delves into the ways in which dietary choices influence heart health, providing evidence-based strategies to lower heart disease risk and enhance overall cardiovascular well-being through straightforward and achievable dietary modifications.

How Your Diet Influences Heart Health

The health of your heart is significantly influenced by your diet, as the foods you consume provide essential nutrients that your body needs to operate efficiently, including proteins, carbohydrates, fats, vitamins, and minerals. Risk factors for heart disease are divided into modifiable and non-modifiable categories. Diet is a modifiable risk factor because you have the power to change it, unlike age or genetics, which are beyond your control.

In particular, dietary choices can help mitigate the following risk factors associated with heart disease:

• Blood Pressure: High blood pressure can damage blood vessels and constrict arteries, increasing the strain on your heart. This condition may lead to an enlarged heart and elevate the risk of heart failure. Numerous studies indicate that a balanced diet low in sugars, calories, and sodium, yet rich in nutritious foods such as vegetables, nuts, olive oil, and fish, is associated with lower occurrences of high blood pressure.
• Blood Lipids: Increased levels of blood lipids, which include low-density lipoprotein (LDL, or “bad”) cholesterol and triglycerides, can lead to atherosclerosis and a heightened risk of heart disease. Consuming a diet that is low in saturated fats and refined, processed foods can significantly lower this risk.
• Blood Sugar and Insulin: Elevated blood sugar levels and insulin resistance can result in the buildup of harmful compounds and oxidative stress, which may impair heart function. This can pave the way for diabetes and coronary artery disease (CAD), particularly if your diet is high in ultra-processed foods and added sugars.
• Body Weight: A diet rich in calorie-dense foods, typical of Western diets, often leads to weight gain and associated heart issues, such as fibrosis, hypertension, and elevated blood lipids. Consequently, obesity is a known risk factor for heart disease; however, even excess abdominal fat can pose a significant risk on its own.

Addressing Weight Discrimination

While research commonly points to obesity as a risk factor for various health conditions, it often overlooks the impact of weight stigma and discrimination on health outcomes. Such discrimination is one of the social determinants of health—factors encountered in daily life that affect overall health—and can contribute to health disparities. Experiences of weight stigma, whether in everyday situations or within healthcare settings, can lead to adverse mental and physical health outcomes.

Everyone is entitled to respectful and compassionate medical care. If you are seeking healthcare professionals who adopt a weight-inclusive approach, consider following the initiatives of the Association for Size Diversity and Health, which is working on a directory set to be released in the summer of 2022.

Heart-Healthy Diets

Over the years, extensive research has highlighted the diets most linked to maintaining a healthy heart and reducing the risk of cardiovascular diseases.

Mediterranean Diet

The Mediterranean diet stands out as one of the best dietary patterns for promoting heart health. It emphasizes the consumption of plant-based foods such as lentils (masoor dal), a variety of vegetables, fruits, whole grains, seafood, and healthy fats like extra virgin olive oil and nuts, while minimizing the intake of ultra-processed foods, red and processed meats, and added sugars. Research indicates that adherence to a Mediterranean-style diet may lower heart disease risk significantly, with some studies suggesting a reduction of up to 30%.

Incorporating Cultural Foods into a Mediterranean Diet

Adopting an eating pattern inspired by the Mediterranean diet does not necessitate the exclusion of your own cultural foods. It is essential to integrate foods that are locally available and hold personal significance. For instance, one can explore the idea of adapting the Mediterranean diet with Caribbean flavors and ingredients.

Plant-Based Diets

Various forms of plant-based diets, including vegetarian, vegan, and flexitarian options, have shown strong correlations with improved heart health and a lower risk of heart disease. A comprehensive review from 2021 encompassing 10 studies with 698,707 participants revealed that individuals adhering closely to plant-based diets had a significantly lower incidence of heart disease. However, it is crucial to note that plant-based diets high in refined grains, sugary drinks, and highly processed snacks may actually increase heart disease risk. Overall, the most heart-healthy diets are rich in plant foods such as vegetables, fruits, legumes, nuts, and seeds, while remaining low in ultra-processed foods, red meats, and added sugars.

What to Eat and Avoid for a Heart-Healthy Diet

Consuming a diet abundant in vegetables and fruits has been consistently associated with enhanced heart health outcomes and lower risks of conditions such as hypertension and diabetes.

Foods to Include

Your overall dietary pattern plays a crucial role in disease prevention; however, incorporating the following foods into your meals can significantly enhance heart health and overall well-being.

• Fruits: While all fruits offer health benefits, citrus fruits, apples, pears, and berries are particularly beneficial. These fruits are rich in fiber, essential vitamins, minerals, and antioxidants such as anthocyanins, which combat inflammation.
• Vegetables: Research indicates that onions, garlic, cruciferous vegetables, leafy greens, and carrots may provide greater cardiovascular benefits compared to other vegetables, although all vegetables contribute positively.
• Seafood: Seafood is an excellent source of nutrients, especially omega-3 fatty acids, which are beneficial for heart health. Studies have revealed that a 100-gram increase in fish consumption correlates with a reduced risk of coronary heart disease, heart attacks, and heart failure.
• Legumes: Beans and lentils are packed with fiber and essential minerals like magnesium and potassium, which are vital for cardiovascular health. Several studies suggest that diets rich in legumes are linked to lower heart disease rates, though further research is warranted.
• Whole Grains: Foods such as quinoa, brown rice, and oats are high in fiber and nutritionally dense, contributing to improved heart health. Swapping refined grains for whole grains is associated with a reduced risk of heart disease.
• Healthy Fats: Incorporating sources of healthy fats like olive oil, olives, nuts, seeds, fatty fish, and avocados into your diet can enhance heart health. Olive oil, a staple in Mediterranean-style diets, appears to offer particularly strong benefits.
• Spices: Evidence suggests that spices like turmeric, garlic, saffron, and ginger possess powerful anti-inflammatory properties and may aid in reducing factors associated with heart disease.

Foods to Limit

Ultra-processed foods often contain refined carbohydrates, added sugars, saturated and trans fats, sodium, along with various artificial colors, flavors, and preservatives. These components are linked to an increased risk of heart-related issues. For instance, a 2021 study found that each additional serving of ultra-processed food consumed daily was associated with a heightened risk of heart disease.

It is advisable to limit your intake of the following processed foods:

• High-sodium foods
• Fresh or frozen vegetables and meats that come with sauces or marinades
• Pre-packaged sauces or ready-to-eat rice and pasta
• Fatty meats or poultry with skin
• Butter, lard, or oils like coconut and palm oil
• Sweetened snacks, desserts, and beverages

That said, the term “processed foods” encompasses a variety of products, many of which can be more convenient and cost-effective than fresh options. Not all processed foods are unhealthy or detrimental to your health. To better understand how to distinguish between nutritious food and junk food, explore more about food labeling. Nonetheless, cooking your meals at home as much as possible is beneficial, as restaurant or pre-packaged foods tend to be more processed and less heart-healthy.

Dining out doesn’t have to be completely off the table; simply be mindful of your selections and read labels thoroughly. Additionally, if you consume alcohol, it is advisable to limit your intake to two drinks or less if you identify as male and one drink or less if you identify as female. Learn how to interpret food labels effectively.

[Defining the Terms “Male” and “Female”]

In this article, we refer to “male” and “female” in relation to biological sex as determined by chromosomes, while “men” and “women” denote gender identity (unless quoting sources that utilize non-specific terms). Biological sex is determined by chromosomes, whereas gender is a social construct that varies across time and cultures. Both aspects are recognized to exist on a spectrum, supported by historical context and modern scientific understanding.
