Understanding Cardiovascular Disease (CVD)
Cardiovascular disease (CVD) refers to a group of disorders that impact the blood vessels and the heart, including stroke, hypertension, and coronary artery disease. It is considered to be one of the leading causes of mortality across the world. It is often linked to poor dietary habits, genetic predisposition and sedentary lifestyles. Heart disease may develop gradually due to plaque build-up in arteries. It may restrict blood flow and increase the risk of heart attacks and strokes.
Importance of Diet in Maintaining Better Heart Health
To maintain optimal heart health, people must opt for a well-balanced diet that helps significantly regulate cholesterol levels, inflammation, and blood pressure. Nutritional choices may impact the risk of developing cardiovascular disease. Thus, dietary interventions serve as a powerful tool for prevention and management. It is essential to prioritise nutrient-dense foods and avoid harmful dietary components to enhance cardiovascular well-being and reduce complications associated with heart disease.
What is a Cardiac Diet?
A cardiac diet encourages people to eat heart-healthy and anti-inflammatory foods to help reduce the risk of cardiovascular disease. According to the American Heart Association (AHA), below are the basic principles of a cardiac diet:
Limit sugar and salt intake.
Include a variety of fruits, such as berries, bananas, oranges, and vegetables, such as carrots, tomatoes, leafy greens, and sweet potatoes.
Choose whole grains like quinoa, brown rice and barley instead of highly refined or white grains.
Cook with non-topical plant oils like olive oil.
Limit highly processed foods.
Get protein from plant sources such as nuts, seeds, and legumes.
If including animal products in the diet, one can choose:
Fish and seafood.
Low-fat or fat-free dairy.
Lean meats.
Recommended Cardiac Diets
Below are a few recommended cardiac diets that heart patients can choose:
Mediterranean Diet: This diet focuses on fruits, vegetables, legumes, whole grains, and olive oil.
DASH Diet (Dietary Approaches to Stop Hypertension): This diet intends to help lower blood pressure. It promotes eating plant-based whole foods while avoiding sugar, salt, and most fats.
Vegetarian Whole-Food Diet: This diet replaces animal proteins with plant-based sources such as legumes and nuts, which are beneficial for heart health.
It was found that the DASH diet, the vegetarian diet, and the Mediterranean diet have the most evidence for cardiovascular disease prevention. Both the Mediterranean and DASH diets offer substantial cardiovascular benefits. However, the key difference lies in sodium restriction (DASH) versus a focus on healthy fats (Mediterranean). Individuals can choose a diet based on personal preferences and health needs.
Steps to Prevent Cardiovascular Disease
Certain foods can raise heart disease risk. Even though changing eating habits can be challenging, simple steps can help. Below are a few essential steps to prevent cardiovascular disease:
1. Consuming More Vegetables and Fruits
Vegetables and fruits are good sources of vitamins and minerals, mostly low in calories and rich in fibre. Like other plant-based foods, they contain substances that may help prevent heart disease.
2. Controlling Portion Sizes
How much one eats is as important as what one eats. Overeating can lead to consuming more calories than one should. Hence, it is essential to follow a few simple tips for controlling food portion size, such as below:
Eat more nutrient-rich and low-calorie foods.
Use a small bowl or plate to help control portions.
Avoid high-sodium and high-calorie foods such as refined, processed and fast foods.
3. Choosing Whole Grains
Whole grains provide fibre and other nutrients that are crucial for heart health and controlling blood pressure. Healthy choices include whole-grain farro, barley, and quinoa.
4. Limiting Unhealthy Fats
Limiting the amount of saturated and trans fats is necessary to help lower blood cholesterol and lower the risk of a common heart condition called coronary artery disease. High blood cholesterol may lead to a build-up of plaques in the arteries called atherosclerosis. This may increase the risk of heart attack and stroke. The American Heart Association offers guidelines for the amount of fat to include in a heart-healthy diet.
| Type of Fat | Recommendations |
| Saturated Fat | Less than 6% of total daily calories. |
| Trans Fat | Recommended to avoid it totally. |
5. Limiting Sodium and Salt
Eating foods with higher quantities of sodium can lead to high blood pressure, a risk factor for heart disease. Hence, limiting or avoiding salt and sodium is key to a heart-healthy diet.
6. Choosing Low-Fat Protein Sources
Choosing low-fat protein options such as:
Skinless chicken breasts rather than fried chicken patties and skimmed milk instead of whole milk can contribute to a heart-healthy diet.
Fish is healthier than high-fat meats. Certain types of fish are rich in omega-3 fatty acids, which help lower blood fats called triglycerides.
Legumes like peas, lentils, and beans are also good low-fat sources of protein. They contain no cholesterol, making them good substitutes for meat.
Role of Nutrition in Preventing CVD
Below-mentioned nutrients play a crucial role in maintaining excellent heart health:
Antioxidants: They protect against oxidative stress and inflammation and are found in green tea, berries, and dark chocolate.
Fibre: Fruit, legumes, and whole grains can reduce cholesterol, which also aids digestion.
Omega-3 Fatty Acids: They help reduce inflammation, improve heart function, and support circulation.
Potassium and Magnesium: They are crucial for regulating blood pressure, relaxing blood vessels and maintaining normal heart rhythm. These minerals are found in abundance in spinach, bananas, and nuts.
Cooking Techniques and Meal Planning for Heart Health
A few cooking techniques, as below, can help contribute to a heart-healthy diet:
Steaming, grilling, and baking are healthier options than frying. This helps in reducing unnecessary saturated fat intake.
Using olive oil instead of butter or margarine supports heart health, providing healthy monounsaturated fats.
One can also create a meal plan for better heart health. Below are a few tips:
Preparing meals in advance helps in ensuring better portion control and healthier choices.
Consuming a variety of nutrient-dense foods in daily meals supports overall cardiovascular health and reduces reliance on processed foods.
Lifestyle Changes to Prevent Cardiovascular Disease
One must follow a few essential lifestyle changes to prevent CVD, such as below:
Regular Physical Activity: Regular exercises help in enhancing heart function, reducing blood pressure and aiding weight management. Aiming for at least 150 minutes of moderate-intensity exercise every week, such as cycling, brisk walking, or swimming, can help improve heart health.
Stress Management: Chronic stress may contribute to hypertension and unhealthy eating habits. Practices such as yoga, meditation, and deep breathing can reduce stress hormone levels and support heart health.
Conclusion
To maintain better heart health, one must choose a diet that consists of nutrient-rich foods like vegetables, fruits, lean proteins, whole grains and healthy fats while limiting sugar, sodium and processed foods. Small but consistent changes in diet and lifestyle may lead to long-term heart health benefits. Combining proper nutrition with regular exercises and stress management can help in creating a holistic approach to cardiovascular wellness. It is necessary to prioritise heart health through mindful dietary choices and lifestyle habits to reduce the risks of CVD. Individuals can attain optimal health and well-being by embracing balanced and sustainable nutrition.
