What You'll Learn
Eating fruits and vegetables
According to Canada's Food Guide, filling half your plate with fruits and vegetables at each meal may help reduce your risk of heart disease and stroke. This is because they are excellent sources of vitamins C and A, in the form of beta-carotene. These vitamins act as antioxidants, helping to slow down or prevent atherosclerosis by reducing the buildup of plaque in your arteries.
Leafy green vegetables, in particular, have been associated with significant benefits to cardiovascular health. They are rich in vitamin K and nitrates, which can help reduce blood pressure and improve arterial function. The American Heart Association recommends increasing your intake of leafy greens to lower your risk of heart disease.
When it comes to fruits, berries are especially beneficial for heart health. Strawberries, blueberries, blackberries, and raspberries are packed with nutrients and antioxidants like anthocyanins, which protect against oxidative stress and inflammation that contribute to heart disease. Consuming blueberries daily may also improve vascular function, helping to control blood pressure and blood clotting.
Avocados are another excellent choice for heart health due to their high content of heart-healthy monounsaturated fats. Eating at least two servings of avocado per week has been linked to a reduced risk of cardiovascular and coronary heart disease. Avocados are also a good source of potassium, which is essential for maintaining healthy blood pressure.
In addition to fresh produce, frozen and canned fruits and vegetables can also provide similar nutritional value. However, when purchasing canned or packaged products, it is important to choose options with no added sugar, syrup, or salt to preserve heart health. Overall, incorporating a variety of fruits and vegetables into your diet is a delicious and nutritious way to promote and maintain the health of your heart.

Limiting alcohol consumption
A healthy diet is key to preventing and managing cardiovascular disease. It involves eating a well-balanced diet with a variety of foods, including fruits and vegetables, and limiting the consumption of foods high in saturated fat, sugar, and salt. In addition to diet, regular physical activity is essential for maintaining a healthy weight and improving cardiovascular fitness.
When it comes to alcohol consumption, moderation is crucial. Excessive drinking is linked to various adverse health outcomes, including heart-related issues. Heavy drinking can lead to high blood pressure, heart failure, stroke, and cardiomyopathy, a disorder affecting the heart muscle. Therefore, it is recommended to limit alcohol consumption to no more than two drinks per day for men and one drink per day for women.
While some studies suggest that moderate alcohol intake may be associated with a lower risk of dying from heart disease, the relationship between alcohol consumption and heart health is complex. Alcohol consumption can have both positive and negative effects on the cardiovascular system, and it is essential to consider individual factors such as genetic and behavioural variants.
Red wine has been the subject of debate, with some scientific studies indicating that small amounts may be linked to improved heart health due to its antioxidants. However, this could also be attributed to lifestyle factors beyond alcohol consumption, such as higher incomes and access to healthier foods. Additionally, alcohol is a source of excess calories, which can contribute to weight gain and obesity, further emphasising the importance of moderation.
For individuals with certain heart conditions, such as heart rhythm abnormalities or heart failure, abstaining from alcohol may be the recommended course of action. It is always essential to consult with a healthcare professional to determine the appropriate level of alcohol consumption based on individual circumstances and health status.

Choosing healthy sources of protein
A healthy diet and lifestyle are key to preventing and managing cardiovascular disease. It is important to eat a well-balanced diet with a variety of foods in the right amounts to give your body what it needs. This includes choosing healthy sources of protein.
Firstly, it is important to note that most people are getting far more protein than they need, especially when it comes to meat. More than half of Americans do not meet the recommended intake of seafood, nuts, seeds, and soy products. Consuming extra protein often comes from eating meats high in saturated fats, which can increase "bad" cholesterol levels. Therefore, it is important to choose lean cuts of meat and trim visible fat before cooking. Red meat should be eaten in moderation as it has been linked to an increased risk of heart disease. Processed meats like bacon, sausages, salami, and ham should be avoided as they increase the risk of heart disease.
Instead, opt for plant-based proteins such as legumes (including beans, chickpeas, lentils, and soy protein), nuts, and seeds. These are not only high in protein but also fibre. Legumes are also low in fat and an inexpensive alternative to meat. For example, legumes can pack about 16 grams of protein per cup. Regularly eating unsalted nuts and seeds as part of a heart-healthy diet can help lower total and LDL ("bad") cholesterol and your risk of heart disease.
Fish and seafood are also good sources of protein and healthy fats. Include fish in your diet 2-3 times a week, especially oily fish such as salmon, sardines, trout, mackerel, herring, anchovies, tuna, and sprats, which are high in polyunsaturated fats and omega-3 fats. Omega-3 fats may help prevent blood clots and lower blood pressure. When buying tinned fish, be mindful of salt and other ingredients, and choose unflavoured options. Frozen or tinned seafood can be a cheaper and more convenient alternative to fresh fish.
If you eat meat and poultry, ensure it is lean and unprocessed. Chicken is a good source of protein and can be eaten as part of an overall heart-healthy diet, alongside other good sources of protein and plant foods. For heart health, limit your weekly intake of cooked red meat to less than 1-3 meals (350 grams) per week.
Other sources of protein include low-fat or fat-free dairy, and eggs, which also provide other sources of nutrients that benefit your health. Healthy individuals can include up to a whole egg or the equivalent daily.

Minimising processed foods
Minimising the consumption of processed foods is a key recommendation of the American Heart Association (AHA) for ideal heart health. Processed foods are often high in sodium (salt), saturated fat, added sugars, and alcohol, which should be avoided to protect your heart.
Processed meats, such as sausages, bacon, and cured meats, have been linked to an increased risk of heart disease and other illnesses. If you currently consume more than 90g of processed meat per day, try to reduce your intake to no more than 70g. When preparing meat, remove the skin and visible fat to reduce your saturated fat intake.
Instead of processed meats, opt for lean meats such as 95% lean ground beef, pork tenderloin, or skinless chicken or turkey. If you're a fan of seafood, include tuna, cod, haddock, and tilapia in your diet. Oily fish like salmon, sardines, trout, mackerel, herring, and sprats are also excellent choices.
In addition to meat and seafood, incorporate plant-based sources of protein such as legumes and nuts into your meals. Choose nonfat or low-fat dairy options, which can increase your unsaturated fat intake while lowering saturated fat consumption. Examples of healthy oils for cooking include canola, corn, olive, soybean, safflower, and sunflower oils, which are high in monounsaturated and polyunsaturated fats—the best types of fat for heart health.
By minimising processed foods and making these simple substitutions, you can significantly improve your heart health and overall well-being. Remember, it's not just about the foods you cut out but also about finding healthier alternatives and enjoying the food you eat.

Maintaining a healthy body weight
It is important to know how many calories you should consume and burn to maintain your weight. This will depend on several factors, including age, gender, and level of physical activity. As a general guideline, nutrition labels on food products are based on a 2,000-calorie-per-day diet. You can increase your calorie expenditure by engaging in regular physical activity. Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous activity per week, or a combination of both. If it's challenging to schedule dedicated exercise, try incorporating short bursts of activity into your daily routine, such as taking the stairs instead of the elevator.
Making mindful dietary choices is also crucial for maintaining a healthy body weight. Focus on consuming a variety of fruits and vegetables, as they are associated with a reduced risk of cardiovascular disease. Opt for whole grains instead of refined grains, and choose healthy sources of protein, such as plants, seafood, or lean meats. Minimise your intake of processed meats, as they have been linked to an increased risk of heart disease. Instead, go for lean meats like skinless chicken or turkey, or plant-based proteins like legumes and nuts.
Additionally, pay attention to the types of fat in your diet. Reduce your consumption of saturated fats found in butter, lard, ghee, coconut oil, and palm oil. Prioritise unsaturated fats, which are associated with better cardiovascular health. Good sources of unsaturated fats include seafood, nuts, seeds, avocados, and oils such as olive oil, soybean oil, and sunflower oil.
Remember, maintaining a healthy body weight is about finding a balance between your calorie intake and physical activity. Making small, sustainable dietary changes and incorporating regular movement into your routine can help you achieve and maintain a healthy weight, benefiting both your overall health and heart health.
