What Are Antioxidants Rich Foods And Drinks

what are antioxidants rich foods

Antioxidants are compounds produced in your body and found in foods. They help defend your cells from damage caused by potentially harmful molecules known as free radicals. When free radicals accumulate, they may cause a state known as oxidative stress. This may damage your DNA and other important structures in your cells. There are many antioxidants rich foods are available on this planet like broccoli, spinach, carrots, and potatoes are all high in antioxidants, and so are artichokes, cabbage, asparagus, avocados, beetroot, radish, lettuce, sweet potatoes, squash, pumpkin, collard greens, and kale. But we are going to discuss the details on this topic.

What Are Antioxidants Rich Foods

Dark Chocolate

Lucky for chocolate lovers, dark chocolate is nutritious. It has more cocoa than regular chocolate, as well as more minerals and antioxidants. Based on the FRAP analysis, dark chocolate has up to 15 mmol of antioxidants per 3.5 ounces (100 grams). This is even more than blueberries and raspberries, which contain up to 9.2 and 2.3 mmol of antioxidants in the same serving size, respectively.

Moreover, the antioxidants in cocoa and dark chocolate have been linked to impressive health benefits such as less inflammation and reduced risk factors for heart disease. For example, a review of 10 studies looked at the link between cocoa intake and blood pressure in both healthy people and those with high blood pressure.

Consuming cocoa-rich products like dark chocolate reduced systolic blood pressure (the upper value) by an average of 4.5 mmHg and diastolic blood pressure (the lower value) by an average of 2.5 mmHg. Another study found that dark chocolate may reduce the risk of heart disease by raising blood antioxidant levels, raising levels of “good” HDL cholesterol, and preventing “bad” LDL cholesterol from becoming oxidized. Oxidized LDL cholesterol is harmful because it promotes inflammation in the blood vessels, which can lead to an increased risk of heart disease.

Pecans

Pecans are a type of nut native to Mexico and South America. They are a good source of healthy fats and minerals, plus contain a high amount of antioxidants. Based on a FRAP analysis, pecans contain up to 10.6 mmol of antioxidants per 3.5 ounces (100 grams). In addition, pecans can help raise antioxidant levels in the blood. For example, a study found that people who consumed 20% of their daily calories from pecans experienced significantly increased blood antioxidant levels.

In another study, people who consumed pecans experienced a 26–33% fall in oxidized blood LDL levels within two to eight hours. High levels of oxidized LDL cholesterol in the blood are a risk factor for heart disease. Although pecans are a great source of healthy fats, they are also high in calories. So it’s important to eat pecans in moderation to avoid consuming too many calories.

Blueberries

Although they are low in calories, blueberries are packed with nutrients and antioxidants. According to a FRAP analysis, blueberries have up to 9.2 mmol of antioxidants per 3.5 ounces (100 grams). Several studies even suggest that blueberries contain the highest amount of antioxidants among all commonly consumed fruits and vegetables.

In addition, research from test-tube and animal studies has shown that the antioxidants in blueberries may delay the decline in brain function that tends to happen with age. Researchers have suggested that the antioxidants in blueberries may be responsible for this effect. They’re thought to do this by neutralizing harmful free radicals, reducing inflammation, and changing the expression of certain genes. Additionally, the antioxidants in blueberries, especially a type called anthocyanins, have been shown to reduce risk factors for heart disease, lowering LDL cholesterol levels and blood pressure.

Strawberries

Strawberries are among the most popular berries on the planet. They are sweet, versatile and a rich source of vitamin C and antioxidants. Based on a FRAP analysis, strawberries provide up to 5.4 mmol of antioxidants per 3.5 ounces (100 grams). Moreover, strawberries contain a type of antioxidant called anthocyanins, which give them their red color. Strawberries that have a higher anthocyanin content tend to be a brighter red.

Research has shown that anthocyanins may help reduce the risk of heart disease by reducing levels of “bad” LDL cholesterol and raising “good” HDL cholesterol. A review of 10 studies found that taking an anthocyanin supplement significantly reduced LDL cholesterol among people who had either heart disease or high LDL levels.

Artichokes

Artichokes are a delicious and nutritious vegetable not very common in the North American diet. But they have a long history — people in ancient times used their leaves as a remedy to treat liver conditions like jaundice. Artichokes are also a great source of dietary fiber, minerals, and antioxidants. Based on a FRAP analysis, artichokes contain up to 4.7 mmol of antioxidants per 3.5 ounces (100 grams).

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

Goji Berries

Goji berries are the dried fruits of two related plants, Lycium barbarum, and Lycium chinense. They have been a part of traditional Chinese medicine for more than 2,000 years. Goji berries are often marketed as a superfood because they are rich in vitamins, minerals, and antioxidants. Based on a FRAP analysis, goji berries contain 4.3 mmol of antioxidants per 3.5 ounces (100 grams).

In addition, goji berries contain unique antioxidants known as Lycium barbarum polysaccharides. These have been linked to a reduced risk of heart disease and cancer and may help combat skin aging. Moreover, goji berries may also be very effective at raising blood antioxidant levels. In one study, healthy elderly people consumed a milk-based goji berry drink every day for 90 days. By the end of the study, their blood antioxidant levels had risen by 57%.

While goji berries are nutritious, they can be expensive to eat regularly. Moreover, there are only a handful of studies on the effects of goji berries in humans. Though these support their health benefits, more human-based research is needed.

Raspberries

Raspberries are soft, tart berries that are often used in desserts. They are a great source of dietary fiber, vitamin C, manganese, and antioxidants. Based on a FRAP analysis, raspberries have up to 4 mmol of antioxidants per 3.5 ounces (100 grams). Several studies have linked the antioxidants and other components in raspberries to lower risks of cancer and heart disease.

One test-tube study found that the antioxidants and other components in raspberries killed 90% of stomach, colon, and breast cancer cells in the sample. A review of five studies concluded that the anti-inflammatory and antioxidant properties of black raspberries may slow down and suppress the effects of a variety of cancers.

Moreover, the antioxidants in raspberries, especially anthocyanins, may reduce inflammation and oxidative stress. This may reduce the risk of heart disease. That said, most of the evidence for the health benefits of raspberries is from test-tube studies. More research in humans is needed before recommendations can be made.

Kale

Kale is a cruciferous vegetable and a member of the group of vegetables cultivated from the species Brassica oleracea. Other members include broccoli and cauliflower. Kale is one of the most nutritious greens on the planet and is rich in vitamins A, K, and C. It’s also rich in antioxidants, providing up to 2.7 mmol per 3.5 ounces (100 grams).

However, red varieties of kale such as red or and red Russian kale may contain nearly twice as much — up to 4.1 mmol of antioxidants per 3.5 ounces. This is because red varieties of kale contain more anthocyanin antioxidants as well as several other antioxidants that give them their vibrant color. Kale is also a great plant-based source of calcium, an important mineral that helps maintain bone health and plays role in other cellular functions.

Red Cabbage

Red cabbage has an impressive nutrient profile. Also known as purple cabbage, it is rich in vitamins C, K and A, and has a high antioxidant content. According to a FRAP analysis, red cabbage provides up to 2.2 mmol of antioxidants per 3.5 ounces (100 grams). That’s more than four times the amount of antioxidants in regular cooked cabbage. This is because red cabbage contains anthocyanins, a group of antioxidants that give red cabbage its color. Anthocyanins are also found in strawberries and raspberries.

These anthocyanins have been linked to several health benefits. They may reduce inflammation, protect against heart disease, and reduce the risk of certain cancers. What’s more, red cabbage is a rich source of vitamin C, which acts as an antioxidant in the body. Vitamin C may help strengthen the immune system and keep the skin firm.

Interestingly, the way red cabbage is prepared can also affect its antioxidant levels. Boiling and stir-frying red cabbage may boost its antioxidant profile, while steaming red cabbage may reduce its antioxidant content by almost 35%.

Beans

Beans are a diverse group of legumes that are inexpensive and healthy. They are also incredibly high in fiber, which can help keep your bowel movements regular. Beans are also one of the best vegetable sources of antioxidants. A FRAP analysis found that green broad beans contain up to 2 mmol of antioxidants per 3.5 ounces (100 grams).

In addition, some beans such as pinto beans contain a particular antioxidant called kaempferol. This antioxidant has been linked to impressive health benefits, such as reduced chronic inflammation and suppressed cancer growth.

For example, several animal studies have found that kaempferol may suppress the growth of cancers in the breast, bladder, kidneys, and lungs. However, because most of the research supporting the benefits of kaempferol has been in animals or test tubes, more human-based studies are needed.

Beets

Beets, also known as beetroot, are the roots of a vegetable scientifically known as Beta vulgaris. They have a mild taste and are a great source of fiber, potassium, iron, folate, and antioxidants. Based on a FRAP analysis, beets contain up to 1.7 mmol of antioxidants per 3.5 ounces (100 grams). They’re particularly rich in a group of antioxidants called betalains. These give beets their reddish color and have been linked to health benefits.

For example, several test-tube studies have linked betalains to a lower risk of cancers in the colon and digestive tract. Additionally, beets contain other compounds that may help suppress inflammation. For example, a study found that taking betalain capsules made from beetroot extract significantly relieved osteoarthritis pain and inflammation.

Spinach

Spinach is one of the most nutritionally dense vegetables. It’s loaded with vitamins, minerals, and antioxidants, and is incredibly low in calories. Based on a FRAP analysis, spinach provides up to 0.9 mmol of antioxidants per 3.5 ounces (100 grams). Spinach is also a great source of lutein and zeaxanthin, two antioxidants that may help protect your eyes from damaging UV light and other harmful light wavelengths.

These antioxidants help combat damage to the eyes that free radicals may cause over time.
