Risk Factors for Heart Disease and a Healthy Dietary Plan
Have you ever watched a train and wondered how it works? What pulls all the coaches forward? It is the engine—the driving force that keeps the train moving. If the engine develops a mechanical problem, the entire train is affected.
The human body can be viewed in a similar way. The heart acts like the engine of the body, continuously pumping blood to keep all organs functioning. For people living with heart disease, paying attention to diet and lifestyle is particularly important.
What Is the Heart?
The heart is a muscular organ that pumps blood throughout the body through the circulatory system.
It is approximately the size of a person’s fist. It supplies oxygen and essential nutrients to body tissues while helping remove carbon dioxide and other waste products.
When the heart cannot perform these functions properly, vital organs and tissues can be affected.
Major Risk Factors for Heart Disease
Several factors can increase the risk of developing heart disease, including:
Age: The risk of cardiovascular disease generally increases with age.
Sex: Men may develop cardiovascular disease at a younger age, although heart disease is a major health concern for both men and women.
Family history: A family history of heart disease can increase the risk of coronary artery disease.
High blood pressure: Long-term, uncontrolled hypertension can damage and narrow the arteries, increasing the strain on the heart.
High cholesterol: Elevated levels of LDL (“bad”) cholesterol can contribute to plaque buildup in the arteries.
Diabetes: Diabetes significantly increases the risk of cardiovascular disease.
Obesity: Excess body weight can contribute to high blood pressure, abnormal cholesterol levels and diabetes, all of which can affect heart health.
Physical inactivity: Lack of regular physical activity can contribute to weight gain and unhealthy cholesterol levels.
Chronic stress: Prolonged stress may contribute to unhealthy behaviours and can adversely affect cardiovascular health.
Smoking: Smoking damages blood vessels, raises blood pressure and increases the risk of heart disease.
Unhealthy diet: A diet high in saturated fat, trans fat, salt and added sugar can increase the risk of cardiovascular disease.
How to Protect Heart Health Through Diet and Lifestyle.
Choose Healthy Fats
Limit saturated and trans fats. Reduce your intake of deep-fried foods, high-fat meats, bakery products and full-fat dairy products.
Use healthier cooking oils, such as mustard oil, rice bran oil or olive oil, while keeping the overall amount of added oil moderate.
Include sources of omega-3 fatty acids, particularly fish such as locally available oily fish. Plant sources include flaxseeds, walnuts and other nuts.
People with heart disease should discuss their individual fat requirements with a doctor or registered dietitian, especially if they have high cholesterol or other medical conditions.
Limit Salt Intake
Excessive sodium intake can raise blood pressure and increase the workload on the heart.
Limiting salt is therefore an important part of a heart-healthy diet.
Avoid adding extra salt at the table and reduce highly salted processed, packaged and canned foods. Be careful with salty snacks and ready-to-eat foods as well.
Eat More Fruits and Vegetables
Fruits and vegetables provide fibre, vitamins, minerals and a variety of protective plant compounds. Regularly including a variety of vegetables and fruits in the diet can support overall cardiovascular health.
Choose fresh, whole fruits rather than relying on fruit juice. Include vegetables in meals, salads, soups and cooked dishes.
Choose Whole Grains
Whole grains provide dietary fibre, vitamins and minerals and can be part of a heart-healthy eating pattern.
Choose foods such as oats, whole-wheat or red-flour bread, brown rice and locally available whole grains such as millet. Foods containing bran can also help increase dietary fibre intake.
Limit Alcohol
Excessive alcohol consumption can raise blood pressure, contribute to weight gain and increase the risk of several cardiovascular problems. People who drink alcohol should avoid excessive consumption.
Reduce Added Sugar
Eating too much added sugar can contribute to excess calorie intake, weight gain, obesity and metabolic problems. Limit sugary drinks, sweets, desserts and other foods high in added sugar.
Pay Attention to Portion Size
Healthy food can still contribute to excess calorie intake when eaten in large quantities. Use smaller plates, bowls and serving spoons when appropriate.
Avoid ordering more food than you need when eating outside.
Eat slowly and pay attention to feelings of fullness.
Include Antioxidant-Rich Foods
A diet rich in vegetables, fruits, nuts, seeds and other plant foods provides antioxidants and other beneficial compounds.
Garlic, onions, cruciferous vegetables, citrus fruits, berries where available, flaxseeds and nuts can be included as part of a varied, heart-friendly diet.
However, no single food can prevent or cure heart disease. Overall dietary patterns and lifestyle habits are more important.
Stay Physically Active
Regular physical activity supports cardiovascular health and can help control body weight, blood pressure, blood sugar and cholesterol levels.
For many adults, at least 150 minutes of moderate-intensity physical activity per week is recommended. Brisk walking, cycling, swimming, dancing and other suitable aerobic activities can be beneficial.
However, people with diagnosed heart disease, chest pain, severe breathlessness or other cardiac symptoms should consult their doctor before starting or increasing exercise.
Quit Smoking
Smoking is one of the major preventable risk factors for cardiovascular disease. It can damage blood vessels, increase blood pressure and promote the development of arterial plaque.
Quitting smoking is one of the most important steps a smoker can take to protect heart health.
Limit Highly Processed Foods
Many highly processed foods contain excessive amounts of salt, unhealthy fats, added sugar and calories while providing relatively little fibre.
Limit processed meats, packaged snacks, fast foods, instant meals and other highly processed foods. Instead, focus on minimally processed foods such as vegetables, fruits, whole grains, pulses, fish and nuts.
Manage Stress and Get Enough Sleep
Chronic stress can negatively affect overall health and may contribute to unhealthy eating, physical inactivity and poor sleep.
Most adults need around 7–9 hours of sleep each night. Relaxation techniques such as meditation, breathing exercises, reading, gardening, listening to music or pursuing other enjoyable hobbies may help manage stress.
For people with heart disease, dietary and lifestyle changes should be tailored to their medical condition, medications, age and nutritional needs. A qualified physician or registered dietitian can help develop an appropriate individualised meal plan.
