Eat These 13 Foods to Help Lower Cholesterol, Improve Heart Health, and So Much More!

From energizing acai bowls and smooth dark chocolate to creamy kale salads and perfectly roasted sweet potatoes, colorful plant foods have one particular thing in common: Antioxidants. Abundant in many of our daily staples, antioxidants reign supreme. They’re essential for the survival of all living things. They’re foundational to our wellbeing, much like vitamin B12 and iron.

Although we generate our own antioxidants, we also need to consume them. Our bodies’ cells naturally produce powerful antioxidants—such as glutathione—but the foods we eat supply other antioxidants, like vitamin C and E. Between what the body produces and what nature provides, we get the best of both worlds.

What are free radicals?

When we talk about antioxidants, free radicals are involved. You’ll often hear that in order to fight free radicals, antioxidants are key. So what are they, exactly?

Free radicals are highly reactive and unstable molecules. They’re formed when molecules (or atoms) gain or lose electrons. In turn, free radicals can easily react with other molecules. As you can guess, these unpaired electrons don’t like being alone. They search the body for an electron to pair with. When antioxidants are available, they step in. Antioxidants stabilize free radicals, stopping any further damage in the body.

Despite getting a bad rap, we naturally produce free radicals—they’re a byproduct of metabolism and exercise, for example. The issue is when we have an abundance of free radicals. When we have too many for the body to regulate, a condition known as oxidative stress happens. Oxidative stress can be caused by many factors, like, chronic inflammation, smoking, pesticides, radiation, and industrial chemicals. Thankfully, that’s where antioxidants come to the rescue.

What are antioxidants?

Antioxidants are chemicals that help prevent or limit the damage caused by free radicals. They slow the wear and tear to cells caused by oxidative stress. As antioxidants balance free radicals, these free radicals are much less likely (or entirely unable) to cause damage to other cells. Generally speaking, antioxidants are powerful compounds that keep our immune systems working strong. They’re everyday superheroes.

Why do we need antioxidants?

Because antioxidants have the ability to protect the body’s cells against free radicals, we need them in order to optimize our wellbeing. Given their ability to neutralize free radicals, antioxidants boost overall health. Plus, they can potentially ward off certain diseases. Research is underway to investigate the role of antioxidants in decreasing the risk of developing cancer, but consuming foods high in vitamin C, vitamin E, and beta carotene can support the growth of healthy cells.

The most important antioxidants.

Of the hundreds (possibly, thousands) of different substances that can act as antioxidants, the most familiar ones are vitamin A, C, E, beta carotene, lutein, selenium, and manganese. These come in the form of food and supplements—bell peppers, oranges, avocados, carrots, Brazil nuts, etc. These substances are joined by other well-known compounds in the wellness world: coenzyme Q10, lipoic acid, flavonoids, polyphenols, phytoestrogens, and more.

What makes food high in antioxidants?

In addition to the body’s innate ability to keep free radicals in check, eating a diet high in antioxidants is an extra defense layer. Think: Eating the rainbow. Plant foods are abundant in a variety of vitamins and minerals, including immune-boosting antioxidants. These include fruits, vegetables, whole grains, nuts, seeds, herbs, and spices. Those with substantial levels of vitamin A, C, E, beta carotene, lutein, selenium, and/or manganese are all considered foods high in antioxidants.

Specifically, garlic, leeks, sweet potatoes, peppers, broccoli, walnuts, pecans, and berries are all rich sources of antioxidants. When you think about building your breakfast, lunch, and dinner, try to choose the rainbow: red, orange, deep yellow, dark leafy greens, and purples. When possible, buy organic to limit additional exposure to chemicals and pesticides.

Antioxidants as part of a healthy diet.

When it comes to getting enough antioxidants every day, think of adding as many colors to your plate as possible. There isn’t necessarily a target amount of antioxidants, and every person has his or her own unique needs, but eating a variety of plants throughout the day is beneficial. Making a smoothie for breakfast, leafy green salad for lunch and a grain bowl for dinner will certainly include an abundance of antioxidants. Thankfully, red wine and coffee count too. In fact, coffee is one of the highest sources of antioxidants in the American diet.

13 foods high in antioxidants:

Artichokes — may lower bad cholesterol.

Artichokes are especially rich in the antioxidant known as chlorogenic acid. Studies suggest that the antioxidant and anti-inflammatory benefits of chlorogenic acid may reduce the risk of type 2 diabetes and heart disease. However, the antioxidant content of artichokes can vary, depending on how they are prepared. For example, Boiling artichokes may raise their antioxidant content by eight times, and steaming them may raise it by 15 times.

Beets — may protect the liver from inflammation.

Beets (and beetroot juice) contain antioxidants, vitamin A, vitamin B-6, and iron. These compounds help protect the liver from inflammation and oxidative stress while enhancing its ability to remove toxins from the body. Beets are particularly rich in a group of antioxidants called betalains. These give beets their reddish color.

Wild Blueberries — can directly increase antioxidant levels in the body.

One of the highest antioxidant levels of all common fruits and vegetables, blueberries (specifically, wild blueberries) are rich in anthocyanin, a flavonoid with potent antioxidant capacity. The antioxidant king, wild blueberries have two times more antioxidants than ordinary blueberries. With high levels of polyphenols, wild blueberries protect the body against inflammation.

Carrots — may improve heart health.

Carrots have two main types of antioxidants: Carotenoids and anthocyanins. Carotenoids give carrots their orange and yellow colors, while anthocyanins are responsible for red and purple coloring. These antioxidants are known for supporting heart and eye health.

Dark Chocolate — may lower blood pressure.

Dark chocolate is loaded with organic compounds that are biologically active and function as antioxidants. These include polyphenols, flavanols, and catechins, among others. Some research suggests that dark chocolate may help lower the risk of heart disease, reduce inflammation and insulin resistance, and improve brain function.

Goji Berries — can support the immune system.

Goji berries’ purported benefits range from anti-aging effects to glucose regulation and immune function support. Goji berries contain large amounts of vitamins A and C, similarly, to other berries, like blueberries and raspberries. Vitamins A and C are vital for building immunity and preventing illnesses, ranging from the common cold to chronic diseases.

Kale — can counteract oxidative stress.

Kale, like other leafy greens, is very high in antioxidants. These include beta-carotene and vitamin C, as well as various flavonoids and polyphenols. One cup of chopped kale provides well more than your recommended daily allowance of vitamins A, C, and K.

Pecansmay enhance the body’s immune system.

Along with feeling energized and satiated, pecans (like walnuts, almonds, etc.) are high in vitamin A. In fact, research shows that pecans are ranked highest, of any nut, in terms of their antioxidant capacity. It only takes about an ounce (or about 8 pecans) to get its nutritional and antioxidant benefits.

Purple Cabbage — may protect against heart disease.

Purple cabbage, along with other dark-colored produce, is loaded with phytochemicals, antioxidants that may help protect against heart disease. Two of those phytochemicals, anthocyanin, and proanthocyanidin, can support your immune system.

Spinach — can improve digestion.

Spinach’s fresh leaves are a beneficial source of vital antioxidants, like vitamin A, vitamin C, and antioxidant flavonoids such as lutein, zeaxanthin, and beta carotene. Of all leafy greens, like kale, spinach is one of the most nutritionally dense vegetables.

Strawberries — can help maintain healthy vision.

Along with other berries, strawberries are loaded with polyphenols. They are an excellent source of vitamin C and manganese. Strawberries are also rich in antioxidants—possibly benefiting heart health, vision, and blood sugar regulation. In fact, the antioxidant properties in strawberries can help to prevent cataracts.

Walnuts — can decrease heart disease risk factors.

Many health benefits associated with walnuts, such as reduced inflammation and improved heart disease risk factors, are due to their high omega-3 and antioxidant compounds. Their antioxidant levels are particularly high in the papery skin of walnuts, which contain vitamin E, melatonin, and polyphenols.


A diet in antioxidants reduces risk for many diseases (heart disease, cancer, et cetera). Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation. The protective effect of antioxidants continues to be studied around the world. So, eat up those yummy fruits and veggies!

Stay safe, healthy, and live life to the fullest.

Xoxo, Messycafe.
