What You'll Learn
Reduce sodium and fat intake
A healthy diet and lifestyle are key to preventing and managing heart disease. One of the most important things you can do for your heart is to reduce your sodium and fat intake. Here are some tips to help you do that:
Sodium
- Reduce salt intake: While salt is the main source of sodium in our diets, it is not the only source. Many packaged, processed, and prepared foods contain high levels of sodium. Read labels carefully and choose products with reduced or lower sodium content.
- Choose fresh and frozen poultry carefully: Opt for poultry that has not been injected with a sodium solution. Check the packaging for terms like "broth," "saline," or "sodium solution."
- Be mindful of condiments: Condiments such as soy sauce, bottled salad dressings, ketchup, and pickles can be high in sodium. Use these sparingly or look for low-sodium alternatives.
- Enhance flavour with herbs and spices: Instead of relying on salt, experiment with herbs, spices, garlic, onions, citrus juices, and vinegars to add flavour to your meals.
- Opt for reduced-sodium canned and frozen vegetables: Look for canned vegetables labelled "no salt added" and frozen vegetables without salty sauces.
Fat
- Reduce saturated fat intake: Saturated fats are found in meat, cheese, butter, cream, and coconut and palm oil. Limit these foods and replace them with plant-based fats like guacamole, natural peanut butter, and oils made from seeds or plants (olive, avocado, sunflower, etc.).
- Limit trans fats: Trans fats are commonly found in deep-fried foods and partially hydrogenated oils. They are especially harmful to heart health, so minimize your consumption of these fats.
- Choose lean meats and plant-based proteins: If you eat meat, opt for lean cuts and limit your portion size to the size of your palm. Include more plant-based proteins in your diet, such as legumes (beans, lentils), nuts, and seeds.
- Select dairy wisely: If you have high cholesterol, opt for low-fat or non-fat dairy options.
- Moderate egg consumption: If you have high cholesterol, it is recommended to limit your egg intake to no more than seven eggs per week.

Avoid processed foods and sugars
A healthy diet and lifestyle are key to preventing and managing cardiovascular disease. While it's important to understand the number of calories you should be consuming to maintain your weight, it's also crucial to consider the types of foods you're eating.
Processed foods and sugars are often linked to an increased risk of heart disease. Firstly, let's delve into the dangers of processed foods. Ultra-processed foods are made from ingredients extracted from food, such as fat, sugar, and starch, and they often contain additives like artificial flavours, colours, and emulsifiers. These additives can be harmful, and the processing itself can change the molecular structure of foods, creating unhealthy fats like trans fats. Trans fats, found in processed foods like margarine, raise "bad" LDL cholesterol and lower "good" HDL cholesterol, increasing the risk of heart disease and stroke. A study published in the Journal of the American College of Cardiology found that higher consumption of ultra-processed foods is associated with a higher risk of cardiovascular disease incidence and mortality.
Now, let's turn our attention to the negative impact of sugars on heart health. Added sugars, which are commonly found in processed foods, can have serious effects on your heart. These include higher blood pressure, inflammation, weight gain, diabetes, and fatty liver disease, all of which contribute to an increased risk of heart attack and stroke. A 2014 study by Dr. Hu found that people who derived 17% to 21% of their calories from added sugar had a 38% higher risk of dying from cardiovascular disease compared to those consuming only 8% of their calories as added sugar. The American Heart Association recommends that women consume no more than 100 calories (about 6 teaspoons) of added sugar per day, while men should limit their intake to no more than 150 calories (approximately 9 teaspoons) per day.
To improve your heart health, it's important to reduce your consumption of processed foods and sugars. This may involve reading food labels carefully to identify added sugars and limit or avoid certain products. Additionally, increasing your intake of fruits, vegetables, and whole grains can provide a well-rounded diet that contributes to a healthy heart. Remember, it's not just about the number of calories you consume but also the quality of your diet.
In addition to dietary modifications, regular physical activity plays a crucial role in maintaining a healthy heart. Aim for at least 150 minutes of moderate physical activity each week, as recommended by the American Heart Association. This can help you maintain a healthy weight and lower your risk of heart disease.

Eat more fruits and vegetables
Eating more fruits and vegetables is a great way to improve your heart health. This is because they are rich in vitamins, minerals, and antioxidants, which are known to reduce the risk of heart disease.
Fruits and vegetables that are particularly good for your heart include berries, apples, oranges, bananas, mangoes, guava, and papaya. Berries such as strawberries and blueberries are packed with antioxidants, which protect against oxidative stress and inflammation that can contribute to heart disease. Similarly, tomatoes are loaded with lycopene, a natural plant pigment and antioxidant that can prevent oxidative damage and inflammation. Other fruits and vegetables that are high in antioxidants include peppers, edamame, beets, and carrots.
Leafy green vegetables such as kale, spinach, and bok choy are also excellent choices for heart health. They are rich in vitamin K and nitrates, which help to reduce blood pressure and improve arterial function. Research has found that people who ate the most nitrate-rich vegetables, especially leafy greens, lowered their risk of cardiovascular disease by 12% to 26%.
When incorporating more fruits and vegetables into your diet, remember that variety is key. Aim for a rainbow of colours on your plate to ensure you're getting a range of nutrients. Fresh, canned, frozen, or dried fruit are all great options, but be mindful of added sugars in canned or dried fruit.
In addition to a healthy diet, regular physical activity is also important for maintaining heart health. Aim for at least 150 minutes of moderate activity or 75 minutes of vigorous activity each week to keep your heart strong and healthy.

Exercise regularly
Exercise has a multitude of benefits for heart health. Firstly, it helps to lower blood pressure and triglycerides, which is a type of fat found in the blood. Regular exercise also raises HDL ("good") cholesterol levels, which can reduce the risk of heart disease. Additionally, physical activity can help maintain a healthy weight, which is crucial in preventing heart-related issues.
The American Heart Association and the American College of Sports Medicine recommend a combination of aerobic exercise and resistance training. Aerobic exercises include jogging, swimming, and biking, all of which are great for improving cardiovascular health. Resistance training, such as moderate weightlifting, helps to strengthen the body's musculoskeletal system.
For those who are pregnant, it is beneficial to maintain a moderate exercise routine if you were physically active before pregnancy. Walking, swimming, and bike riding are excellent ways to keep active during pregnancy and continue to receive cardiovascular benefits. However, it is always important to consult with your physician before starting or continuing an exercise program, especially during pregnancy.
The amount of exercise recommended is at least 150 minutes of moderate physical activity or 75 minutes of vigorous activity per week. This can be achieved through activities such as walking, which can be done in 10- to 15-minute bouts throughout the day. It is also essential to minimise sedentary behaviour, as sitting for extended periods has been linked to increased heart risks.
In addition to the direct benefits on heart health, regular exercise has been shown to improve cognitive function, reduce symptoms of depression, and decrease anxiety. It can also help with weight loss and improve overall quality of life.

Limit alcohol consumption
While a healthy diet and lifestyle are key to preventing and managing cardiovascular disease, limiting alcohol consumption is a crucial aspect of maintaining a healthy heart. Alcohol is a depressant drug that can negatively impact your heart health in several ways. Firstly, excessive alcohol intake can lead to increased blood pressure, which is a significant risk factor for heart disease. High blood pressure can cause fatty plaques to build up in the arteries, increasing the chances of a heart attack or stroke.
Heavy drinking is also associated with heart failure, stroke, and cardiomyopathy, a condition that affects the heart muscle. Additionally, alcohol contributes to weight gain and obesity, which are also risk factors for heart disease. Alcohol is a source of excess calories, and the associated weight gain can have harmful long-term effects. Binge drinking, in particular, has been linked to a higher risk of heart disease in both men and women.
To reduce the risk of alcohol-related heart problems, it is essential to limit alcohol consumption. While there is no completely safe level of alcohol intake, moderation is key. The recommended weekly limit is 14 units of alcohol, which is equivalent to 6 pints of average-strength beer or 6 medium glasses of average-strength wine. It is best to spread this over at least three days and include several alcohol-free days each week.
If you are concerned about your alcohol consumption or its impact on your health, there are several strategies you can implement to reduce your intake. These include setting a drink limit, drinking water or soft drinks between alcoholic beverages, and choosing alcohol-free or low-alcohol alternatives. Additionally, avoiding rounds and buying your drinks individually can help you control your consumption. Remember, a healthy dietary pattern and regular physical activity are also essential components of maintaining a healthy heart.
