Superfoods have been around for a long time, but it is only recently that researchers have found that superfoods can be beneficial for people with heart disease or high cholesterol.1 There are many superfoods that are great for your heart. Some of these can help reduce inflammation, lower your cholesterol levels, and slow down the formation of plaque – all factors that help reduce the risk of heart disease.
A good diet is necessary to have a healthy heart. You should ensure that you consume plenty of:
- Whole-grain foods
- Vegetables and fruits
- Nuts and seeds
- Protein-rich beans
- Fish and skinless poultry
- Low-fat dairy products
At the same time, you should restrict or avoid the intake of:
- Red meat
- Sugar and sugary drinks
- Refined grains
- Saturated and trans fats
- And junk food in general.
However, even if you know about all this, it still becomes difficult to find the best superfoods for your heart. Here are some of the best superfoods for your heart.
13 Awesome Superfoods For Your Heart
Leafy Green Vegetables
Leafy green vegetables like collard greens, kale, and spinach are famous for being powerhouses of vitamins, minerals, antioxidants, and many other essential nutrients that your body needs.
Green leafy vegetables are especially a great source of vitamin K. Vitamin K is necessary for protecting your arteries and promoting proper clotting of blood.2,3
Green leafy vegetables are also rich in dietary nitrates, which are known to lower your blood pressure, reduce arterial stiffness, and also improve the functioning of the cells that line your blood vessels.4
Several studies have also found that there is a link between a higher intake of leafy green vegetables and a lower risk of heart disease. For example, a 2010 study done on 29,689 women participants found that an increased intake of leafy green vegetables was linked to a dramatically lower risk of heart disease.5 Another analysis of eight studies discovered that increasing the intake of leafy green vegetables was linked with a 16 percent lower rate of coronary heart disease.6
You can include the following leafy greens in your diet:
All types of berries are good for your heart. Blueberries, strawberries, raspberries, and blackberries are all powerhouses of many critical nutrients that play a significant role in your heart health. Berries are also a rich source of antioxidants like anthocyanins. Anthocyanins help protect against inflammation and oxidative stress that are known to contribute to the development of heart disease.7
Studies have found that consuming a lot of different types of berries can help reduce many of the risk factors for heart disease. For example, a 2010 study carried out in 27 adults with metabolic syndrome found that having a drink made of freeze-dried strawberries for eight weeks lowered the levels of LDL (bad) cholesterol by 11 percent.8
Metabolic syndrome is a cluster of medical conditions that are linked with an increased risk of heart disease.
Another 2015 study found that consuming blueberries every day helped improve the functioning of the cells that line your blood vessels. This helps control blood clotting and blood pressure.9
The following year in 2016, an analysis of 22 studies found that consuming berries was associated with a decrease in LDL (bad) cholesterol levels, body mass index, systolic blood pressure, and several other markers of inflammation.10
Berries can make for a delicious low-calorie dessert and a satisfying snack that you can munch on through the day. However, it is essential to understand that berry-flavored baked foods do not count as being beneficial to your health. Bakery items are usually loaded with sugar and fat that can be harmful to your heart. So to benefit fully from this superfood, you should opt for eating fresh berries. It is best to include different types of berries in your diet.
You may not immediately think of tomatoes when you think of what to eat to keep your heart healthy. Tomatoes are actually loaded with a natural plant pigment known as lycopene that has potent antioxidant properties.11
Antioxidants are needed by the body to help neutralize the harmful free radicals, preventing inflammation, and reducing oxidative damage, all of which can contribute to heart disease.
Studies have found that people with low blood levels of lycopene are at a higher risk of having a stroke and heart attack.12,13
A study carried out in 50 overweight women participants found that consuming two raw tomatoes four times a week helped boost the levels of HDL (good) cholesterol.14
Having higher levels of HDL cholesterol is helpful in removing excess plaque and cholesterol from your arteries. This helps your heart remain healthy and also protects against stroke and heart disease.15
Another review of 25 studies found that high consumption of foods that are rich in lycopene is linked with a decreased risk of stroke and heart disease.16
Whole grains have a lot of benefits for your overall health. Common types of whole grains include brown rice, whole wheat, rye, barley, oats, quinoa, and buckwheat. As compared to refined grains, whole grains are rich in fiber. Fiber helps reduce LDL (bad) cholesterol and reduces the risk of heart disease.17,18
There are many studies that have found that consuming more whole grains in your diet can be good for your heart. An analysis of 45 studies found that consuming three more servings of whole grains daily was associated with a 22 percent lesser risk of heart disease.19
Another study also found that if you have at least three servings of whole grains, it can dramatically reduce your systolic blood pressure by 6 mmHg, which is sufficient to decrease your risk of stroke by nearly 25 percent.20
Avocados are rich in monounsaturated fats, which are beneficial for your heart. Monounsaturated fats have been associated with lower levels of cholesterol and a reduced risk of heart disease.
A 2015 study looked at the impact of three types of cholesterol-reducing diets in 45 obese and overweight people, out of which one of the test groups was consuming one avocado every day. The study found that the participants of the avocado group experienced significant reductions in LDL cholesterol, as well as a reduction in the levels of small, dense LDL cholesterol. This type of cholesterol is believed to significantly increase the risk of heart disease.21
A 2013 study carried out on 17,567 people found that those who consumed avocados regularly were almost half as likely to develop metabolic syndrome.22
Since avocados are rich in potassium, which is necessary for your heart health, eating them regularly can help you lower blood pressure and also lower the risk of heart attack and stroke. One avocado provides your body with 975 milligrams of potassium, which is about 28 percent of what you need in one day. Consuming 4.7 grams of potassium a day can lower your blood pressure by 8.4/4.1 mmHg, which in turn reduces the risk of stroke by 15 percent.23,24
Other Superfoods That Are Good For Your Heart
Apart from the superfoods mentioned above, there are many other superfoods that are great for your heart. These include:
Fatty Fish And Fish Oil – This includes fish like mackerel, salmon, tuna, and sardines, which are loaded with omega-3 fatty acids. Omega-3 fatty acids are known for their potent heart benefits.
Walnuts – Walnuts are rich in fiber and micronutrients like copper, magnesium, and manganese. Having walnuts regularly can help protect you against heart disease.
Beans – Beans are rich in resistant starch, which helps improve your heart health by lowering the blood levels of cholesterol and triglycerides.
Dark Chocolate – Dark chocolate is a powerhouse of antioxidants like flavonoids, which boost your heart health. It also lowers the risk of heart disease.
Almonds – Almonds are nutrient-dense and contain a host of vitamins and minerals that are important for your heart health.
Garlic – Garlic has powerful medicinal properties and helps improve heart health owing to the presence of a compound known as allicin. Allicin has a wide variety of therapeutic effects, including for the heart.
Olive Oil – The heart-healthy benefits of olive oil are well known and scientifically proven. This oil is rich in antioxidants that help relieve inflammation and also lowers the risk of several chronic diseases.
As new evidence emerges every year, the link between heart disease and your diet is growing stronger. What you eat can have a great influence on your heart health – from your blood pressure levels to cholesterol levels, inflammation, and even triglycerides. So including these heart-healthy superfoods as part of your daily diet can help keep your heart in good health and also cut down the risk of heart disease.
