Heart disease is one of Australia’s biggest health problems. It’s the single leading cause of death, killing one Australian every 12 minutes.1
Through healthy eating, exercising and cessation of smoking, these deaths are largely preventable.1
Some foods contain properties which are shown to naturally benefit our health and wellbeing. Food can help to reduce blood pressure, triglycerides and blood cholesterol levels, and assist to reduce the risk of developing heart disease.
If you want to keep your heart as healthy as it can be, these are our top 7 heart healthy foods.
1. Leafy green vegetables
Leafy green vegetables include kale, broccoli and cabbage. These contain an abundance of beneficial nutrients that are protective for heart health.2
The nitrates found in these vegetables can increase nitric oxide levels in the body.2 Nitric oxide allows blood vessels to increase in size and muscles to relax.4 It also increases blood flow through the body.4 This can help to lower blood pressure.
Dark leafy green vegetables such as spinach and rocket are also a good source of vitamin K. Vitamin K helps blood clotting and protects the arteries.5
- Add kale, spinach or rocket in a salad.
- Steam broccoli and include as a side with your meals.
- Use cabbage in a stir-fry or add sauerkraut to meals.
2. Beans, legumes and Pulses
Chickpeas, lentils, and black beans are all classified as legumes and pulses. These plant proteins are high in fiber and packed with protein and antioxidants and should be a part of a healthy whole food diet.
Legumes are top heart healthy food. Studies show they can help reduce risk factors for cardiovascular and other chronic diseases. 6,7 This is especially beneficial when increasing legumes in the diet and reducing red meat consumption.
The fiber legumes contain has been shown to reduce total and LDL cholesterol (LDL is the ‘bad’ cholesterol).8,9 Having high cholesterol levels in the blood is a major risk factor for heart disease.
- Try hummus and carrot sticks as a snack.
- Add lentils to soups, stews and salads.
- Try new recipes like chili-non-carne and include a 5 bean mix.
3. Rolled oats
Rolled oats contain a type of soluble fiber known as beta-glucan. Beta glucan is unique in its ability to lower blood cholesterol levels.10 It does this by reducing the amount of cholesterol absorbed from the digestive tract.11
- Have rolled oats as porridge for breakfast.
- Add rolled oats to a smoothie.
- Make healthy energy balls or muesli bars as a mid morning snack.
Blueberries contain one of the highest amounts of antioxidants of most fruits and vegetables. Antioxidants help to protect the body from dangerous cells known as free radicals. These unstable cells can damage healthy cells and may contribute to ageing and disease states.
These antioxidants in blueberries are shown to reduce “bad” LDL cholesterol. This is an important step in the process of cardiovascular disease.12
A new study has also found that eating 150g of blueberries each day could reduce the risk of heart disease by up to 15%.13
- Top your breakfast cereal with fresh berries.
- Blend frozen berries into a smoothie.
- Enjoy a fruit salad including berries as a snack.
5. Dark chocolate
Dark chocolate is packed full of powerful antioxidants. If you’re a chocolate lover, this is good news for you. One study in Norfolk, England followed almost 21,000 residents for 11 years. It found that those with a higher chocolate intake had a lower risk of heart disease.14
Eating chocolate has also been linked with other heart-protective benefits. This includes reducing blood pressure, increasing “good” HDL cholesterol levels and lowering “bad” LDL cholesterol.15,16
Dark chocolate is also a rich source of magnesium, with 16% of the recommended daily intake in a 30g serving.
Having a high magnesium intake in the diet has been linked with a lower risk of diabetes and high blood pressure.17 High blood magnesium levels has also been linked with a reduced risk of heart disease.17
- Enjoy dark chocolate and blueberries as an after-dinner snack.
- Swap your milk chocolate for dark chocolate above 70%.
6. Red wine
The link between red wine and heart health has long been debated.18 Despite this, some studies indicate that wine may have benefits for cardiovascular health.
Red wine is a rich source of a type of antioxidants known as polyphenols. Grapes, especially red grapes, have high levels of polyphenols.19,20 These antioxidants have been shown to reduce inflammation and oxidative stress (where unstable molecules damage your cells).21
Studies show that people who drink red wine in moderate amounts have lower rates of heart disease.22 This antioxidant packed beverage may also help to reduce blood pressure in people with high blood pressure, which may reduce risk of heart disease.23
7. Fatty fish
There are several types of fats that are found in foods which can affect heart disease risk.
Saturated fat is primarily found in animal based foods like full fat dairy and red meat. It has been linked with increasing LDL “bad” cholesterol and risk of heart disease.
Conversely, polyunsaturated and monounsaturated fats found in fatty fish and avocado or olive oil are highly beneficial in lowering “bad” cholesterol and increasing “good” cholesterol levels.24
Unlike other animal proteins, fatty fish is very low in saturated fat and is rich in omega-3 long chain polyunsaturated fats. Fatty fish include salmon, herring, sardines and blue mackerel. They are also a rich source of other beneficial nutrients including selenium, zinc, iodine, vitamin A, and D.
Australians are recommended to be eating 2 -3 serves of fish per week.25 Research indicates that this intake of fish and omega-3 fatty acids is associated with preventing heart disease.25,26,27 There is also some studies indicating that fish and omega-3 supplementation is beneficial in treating heart failure.25
To ensure you are eating enough omega-3, it may be worthwhile to consider our Vitable omega-3 fish oil supplement.
- Have grilled salmon or a serve of fatty fish and vegetables for dinner 2 - 3 times a week.
- Enjoy tinned salmon or tuna on a sandwich or in a salad.
- Have sardines on crackers as a snack.
The bottom line:
The research linking cardiovascular disease and diet grows stronger each day. The foods that you eat have a huge effect on your blood pressure, cholesterol and triglycerides levels. All these factors have an impact on your overall heart health.
Eating heart healthy foods is the number one way to keep your heart functioning at its best. However, to maximise your nutrition when your diet might not be optimal, it may be worthwhile to consider the Vitable supplement range including Vitable’s Fish Oil, Magnesium and Acetyl L-Carnitine.
