Healthy eating to protect your heart

You might have heard that changing the way you eat can impact your health. But what about your heart specifically? 

Poor diet is one of the leading risk factors for heart disease in Australia [1]. What you eat and drink impacts several heart disease risk factors, including:

• Blood pressure 
• Cholesterol 
• Weight 
• Diabetes risk.

What does a heart-healthy eating pattern look like? 

• Enjoying a wide variety of foods focused on fresh and unprocessed food can be good for your heart. 
• A diet naturally low in unhealthy fats, salt and added sugar, and rich in wholegrains, fibre, vitamins, minerals and healthy fats is ideal. 
• Follow our 5-step heart-healthy eating pattern to help you achieve this balance. 

Eat plenty of vegetables, fruit and wholegrains 

Fruit and vegetables are some of the best foods for your heart, but most Australians aren’t eating anywhere near enough. These foods contain a variety of vitamins and minerals, as well as fibre and antioxidants, and have been shown to help prevent heart disease.  

Wholegrains are foods like brown rice, wholemeal pasta, grainy bread and oats. These foods are full of fibre and can help lower your cholesterol. Swapping from refined grains like white bread and white rice to wholegrain versions is a simple change that can improve your diet. 

Include a variety of healthy protein-rich foods 

Some protein-rich foods are better choices than others. The best options are plant-based proteins like beans, chickpeas, lentils, nuts and seeds, as well as fish and seafood. These foods have been shown to reduce your risk of developing heart disease ^[2].  

Eggs and poultry are also protein-rich foods that can be enjoyed as part of a heart-healthy eating pattern.   

If you eat red meat, it’s best to limit it to 1-3 meals per week as research shows it is associated with an increased risk of heart disease ^[3].

Choose unflavoured milk, yoghurt and cheese 

These foods don’t increase or decrease your risk of heart disease, but they can be an important source of calcium, protein and other minerals.  

Unflavoured versions with no added sugar are the healthiest options. 

If you have heart disease or high cholesterol, reduced-fat milk, yoghurt, and cheese are healthier options. For those who don’t, you can choose between reduced-fat or full-fat alternatives. 

Include healthy fats and oils 

Fats and oils can play an important role in your risk of developing heart disease. Different types of fats can impact your health differently—healthy fats can help protect your heart, and unhealthy fats can increase your risk of developing heart disease.   

Choose foods with high amounts of healthy fats such as avocados, olives, nuts and seeds, and use healthy oils for cooking, for example, olive, canola, sunflower, peanut and soybean oil. These foods can help lower your cholesterol.  

Use herbs and spices to flavour foods instead of salt 

Eating too much salt can lead to high blood pressure, which is a risk factor for heart disease. On average, Australians are eating nearly double the recommended amount of salt ^[4].  

Many people don’t realise that most of the salt they eat is found in processed and packaged foods such as canned foods, deli meats (like ham and salami) and baked goods.   

One of the best ways to reduce the amount of salt you eat is to base your diet on fresh, unprocessed foods like fruit and vegetables. If you want to add extra flavour to your food, try adding herbs and spices.  

What foods should I have less of? 

Reducing the amount of highly processed food you eat is great for your heart. Up to 35 per cent ^[5] of the average Australian diet is currently made up of highly processed foods, such as: 

• Baked goods e.g. cakes, biscuits and pastries 
• Chocolate 
• Chips 
• Lollies  
• Sugary drinks e.g. soft drinks, energy drinks, sports drinks 
• Take away food e.g. pizza, burgers. 

These foods are usually high in added sugar, salt, and saturated and trans fats, and they aren’t part of a heart-healthy diet. Try to have these foods only sometimes and in small amounts.   

Avoid over-eating: The ideal portion size

How much you eat is another important part of eating well for your heart. There are some foods we are eating too much of, some foods that we don’t eat enough of, and in general, the size of our meals has grown over time.  
The amount you should eat depends on many factors, including the type of food served. Use a plate with healthy proportions from different food groups as shown below. 


Healthy eating plate made up of 1/2 vegetables, 1/4 carbohydrates and 1/4 protein.

Check to see if your current eating pattern aligns with our healthy eating recommendations.
