What You'll Learn
Reducing sodium and fat intake
The cardiac diet is an eating plan that can help you minimize the impact of your diet on your heart health. The overall goal is to reduce sodium and fat intake. Too much sodium can increase your blood pressure, leading to hypertension, which is a major risk factor for heart attacks and other heart problems.
Reducing sodium intake
Reducing sodium intake is one of the most cost-effective ways to improve health and reduce the risk of heart disease and stroke. The World Health Organization (WHO) recommends a maximum intake of 2000 mg of sodium per day for adults, which is equivalent to less than 5 grams of salt or approximately one teaspoon.
To reduce sodium intake, it is important to read nutrition labels and choose packaged foods labeled "low sodium," "reduced sodium," or "no salt added." Most sodium in our diets comes from packaged and restaurant food, not the salt shaker. So, eating out may require asking for nutrition information and selecting lower-sodium options.
At home, you can replace salt with alternatives like garlic, citrus juices, salt-free seasonings, or spices. Using fresh herbs like basil, bay leaf, dill, rosemary, and parsley can also enhance the flavor of your food without adding sodium.
Reducing fat intake
When it comes to reducing fat intake, it is important to distinguish between healthy and unhealthy fats. For example, oily fish like salmon and tuna are high in omega-3 fatty acids, which are beneficial for heart health. On the other hand, saturated fats, typically from animal-based sources like butter and lard, can increase cholesterol levels and lead to plaque buildup in the arteries.
To reduce unhealthy fat intake, you can make simple substitutions in your diet. For instance, use skimmed milk instead of whole milk, choose lower-fat toppings on pizzas, and opt for leaner cuts of meat like chicken breast instead of beef. When cooking, try baking, broiling, or grilling instead of frying, and use herbs and spices for flavor instead of butter or margarine.
Making these changes can be challenging, but starting with small steps, like replacing butter with olive oil, can help you stick to the cardiac diet and improve your heart health over time.

Limiting alcohol consumption
The cardiac diet is an eating plan that can help minimise the impact of your diet on your heart health. It involves limiting sodium and fat intake, as too much sodium can increase blood pressure, leading to hypertension, a major risk factor for heart attacks and other heart problems. Fat, on the other hand, can cause a plaque buildup on artery walls, also leading to heart disease.
Moderate drinking, defined as no more than one drink per day for women and no more than two drinks per day for men, can be part of a healthy diet and lifestyle. However, it is important to understand the health effects and risks involved with alcohol consumption. While some studies have shown that moderate drinkers have lower rates of heart disease than nondrinkers, there is no research proving a cause-and-effect link between drinking alcohol and better heart health. Additionally, the health benefits seen in moderate drinkers may be due to other factors such as a generally healthier diet and lifestyle, including physical activity and a high consumption of fruits and vegetables.
It is also important to note that drinking alcohol every day can lead to serious cardiovascular disease risks, including high blood pressure, obesity, and stroke. If you find yourself drinking more and more over time, consider cutting back. Alcohol is a source of excess calories and can cause weight gain, which can be harmful in the long term.
Some people believe that a moderate intake of red wine can help protect the heart due to its antioxidant content. However, these antioxidants can also be found in other foods like grapes, grape juice, or blueberries. The American Heart Association does not recommend drinking wine or any other form of alcohol to gain potential health benefits, as regular physical activity is a more effective way to raise HDL cholesterol.
If you choose to drink alcohol, it is important to stick to moderate levels and not overdo it. Additionally, alcohol consumption should be considered in the context of your overall diet and lifestyle. It is crucial to prioritise nutritious, heart-healthy foods and make sure your calorie intake and exercise levels support a moderate weight.

Eating more fruits and vegetables
The cardiac diet is an eating plan that promotes heart health and reduces the risk of cardiovascular disease. It involves limiting sodium and fat intake, as well as processed foods high in sugar and salt, while emphasising foods such as vegetables, fruits, whole grains, lean poultry, and oily fish.
Fruits and vegetables are an essential part of the cardiac diet, and increasing your consumption of these foods can have a positive impact on your heart health. A study conducted by the NHLBI, NIH, found that eating more fruits and vegetables may help lower markers of heart disease. The study involved 326 middle-aged adults with no known pre-existing heart disease, who were assigned eight weeks of monitored feeding with either a control diet, a diet rich in fruits and vegetables, or the DASH diet, which is also rich in fruits and vegetables. The results showed that the heart-healthy DASH diet lowered blood pressure and cholesterol.
Fruits and vegetables are excellent sources of vitamins, minerals, and antioxidants, which are essential for maintaining a healthy heart and body. They are typically low in fat and calories, while being high in dietary fibre, which can help lower cholesterol levels and improve heart health.
When it comes to specific fruits and vegetables, leafy greens such as kale, spinach, and collards are excellent sources of vitamin K, which is important for blood clotting and healthy blood vessels. Citrus fruits like lemons, limes, and oranges are also great for adding flavour to dishes and are rich in vitamin C, which has antioxidant properties. Berries, such as blueberries, are packed with antioxidants and can be a great addition to meals or snacks.
Additionally, choosing a variety of colourful fruits and vegetables will ensure you get a range of different nutrients. For example, red and orange fruits and vegetables like tomatoes, carrots, and apricots are rich in vitamin A and lycopene, which have heart-protective effects. Green vegetables like broccoli, kale, and spinach are packed with vitamins and minerals, including vitamin K, iron, and calcium.
Increasing your fruit and vegetable intake can be a simple and delicious way to improve your heart health and overall well-being. Whether you enjoy them fresh, frozen, or canned, try to incorporate a variety of options into your meals and snacks each day.

Limiting processed foods
The cardiac diet is an eating plan that can help minimise the impact of your diet on your heart health. It involves limiting sodium and fat intake to reduce the risk of cardiovascular disease. Too much sodium can increase blood pressure, leading to hypertension, a major risk factor for heart attacks and other heart problems. Fat, on the other hand, can cause plaque buildup in artery walls, also leading to heart disease.
Processed foods are often high in sodium, sugar, and unhealthy fats, which can negatively affect the heart and overall health. They are usually prepackaged, ready-to-eat, or microwaveable, and can be challenging to give up due to their convenience. Here are some ways to limit processed foods:
- Cook from scratch: Preparing meals from scratch using whole foods allows you to control the ingredients and reduce your intake of sodium, sugar, and unhealthy fats. Whole foods are unprocessed and nutrient-dense, including fruits, vegetables, whole grains, beans, legumes, and nuts.
- Read nutrition labels: Check the nutrition labels of processed and packaged foods to monitor your sodium, sugar, and saturated fat intake. Look for terms like "sodium-free," "reduced sodium," or "low in saturated fat" to make informed choices.
- Choose whole food snacks: Instead of reaching for processed snacks, opt for whole food options like fruits, nuts, or low-fat dairy. This helps satisfy your cravings while providing more nutrients and fewer unhealthy additives.
- Replace processed meats: Processed meats, such as bacon, sausage, and deli meats, are high in sodium, preservatives, and saturated fats. Replace them with plant-based proteins like beans, lentils, or soy products to lower your risk of heart disease.
- Reduce sugar intake: Many processed foods and beverages contain added sugars, especially sodas and energy drinks. Limit your consumption of these drinks, and opt for healthier alternatives like infused water, herbal tea, or unsweetened coffee.
- Gradual changes: Starting and sticking to the cardiac diet can be challenging. Focus on making gradual changes. For example, start by replacing butter with olive oil when cooking, then gradually add other changes like increasing your fruit and vegetable intake.
By limiting processed foods and following the cardiac diet's guidelines, you can effectively reduce your risk of cardiovascular disease and improve your overall heart health.

Adjusting calorie intake and exercise levels
The cardiac diet is an eating plan that promotes heart health and reduces the risk of cardiovascular disease. It involves adjusting calorie intake and exercise levels to achieve and maintain a moderate weight. This includes consuming foods that are low in calories and incorporating physical activity into one's routine.
To adjust calorie intake, individuals should focus on consuming fruits and vegetables, whole grains, lean poultry, and oily fish like salmon and tuna, which are high in omega-3 fatty acids. These foods provide essential nutrients and help maintain a healthy weight. It is also important to limit processed foods, red meat, and refined carbohydrates, as these are typically high in calories and unhealthy fats. For example, individuals can replace butter with olive oil when cooking, as recommended by Hwang. Additionally, sugary foods and beverages, such as soda, baked goods, and candy, should be avoided or limited due to their high-calorie content.
Adjusting exercise levels is also crucial in the cardiac diet. Individuals should aim to incorporate regular physical activity into their routines to burn calories and maintain a healthy weight. This can include activities such as walking, swimming, cycling, or any form of aerobic exercise that the individual enjoys. It is important to consult with a healthcare professional before starting a new exercise routine to ensure safety and determine the appropriate intensity and duration of exercises.
It is important to note that the cardiac diet is not just about calorie counting but also about making healthy food choices. Emphasizing whole, unprocessed foods and limiting saturated and trans fats is essential. This may include choosing non-fat or low-fat dairy products and selecting lean cuts of meat if consuming animal-based sources of protein. Additionally, increasing the intake of mono and polyunsaturated fats, such as olive oil and fatty fish, is recommended as these are considered "good" fats that can help reduce cholesterol levels.
The cardiac diet is a comprehensive approach to improving heart health and maintaining a healthy weight. By adjusting calorie intake through conscious food choices and increasing physical activity, individuals can reduce their risk of cardiovascular disease and promote overall well-being. It is always advisable to consult with a healthcare professional or dietitian before making significant dietary changes to ensure a personalized and safe approach.
