Top 18 antioxidant rich foods

Antioxidants, a type of substance produced in the body, are found in a variety of foods. These substances help to protect cells from potential harm caused by free radicals, which can lead to oxidative stress. This can cause damage to Deoxyribonucleic acid (DNA) and other essential structures in cells, and can increase the risk of chronic disease. Eating an antioxidant-rich food may help to increase the levels of antioxidants in the blood, which in turn can reduce oxidative stress and reduce the risk of diseases. The Fluorescence recovery after photobleaching (FRAP) analysis, which quantifies the amount of antioxidants in a food by neutralizing a free radical, suggests that foods with a higher FRAP value are more likely to contain antioxidants.

This article review the top 18 antioxidant rich foods, and potential risks of taking antioxidant supplements.

Health Benefits of Antioxidants

Eating a healthy diet particularly fruits and vegetables gives antioxidants properties, and provides numerous health benefits, as follows:

  • May help fight oxidative stress 
  • Reduce the risk of developing certain diseases
  • Provides vitamins A, vitamin C, vitamin E, selenium and carotenoids, like beta-carotene, lutein, lycopene, and zeaxanthin

Following are the top 18 antioxidant rich foods:

A. Antioxidant fruits

1. Blueberries –

Blueberries are a superfood because they’re packed with nutrition, vitamins and minerals. Plus, they’re packed with antioxidants, which can help improve brain function, keep bones strong, and lower the risk of heart disease. FRAP analysis shows that blueberries have a whopping 9.2 molts of antioxidants in every 3.5 ounces (100 g) of them. Some studies even said that blueberries have the highest antioxidant capacity of any common fruit. Plus, because they contain antioxidants, they’ve been shown to lower LDL cholesterol and blood pressure, and they’re super low in calories too. And since blueberries are packed with antioxidants, they might even have medicinal benefits for neurological issues, like those related to aging.

2. Strawberries

Strawberries are a widely beloved fruit due to their sweetness, versatility, and antioxidant and vitamin C content. A FRAP analysis indicates that strawberries contain a high concentration of antioxidants, with an average of 5.4 mmol per 3.5 ounces (100 g). Antioxidants such as anthocyanins have been linked to a reduced risk of heart disease, as they are known to reduce levels of LDL cholesterol and raise HDL cholesterol.

Additionally, research has suggested that strawberries may reduce inflammation and lower blood pressure, potentially aiding in the prevention of heart disease. Raw strawberries can be consumed as a snack, in salads, and in baked goods, however, they are rarely healthy and are not recommended for those trying to lose weight.

FRAP analysis shows that raspberries contain up to 4 milligrams (mg) of antioxidants for every 3.5 ounces (100 g) of fruit. Raspberries have been shown to reduce the risk of heart disease and several studies have shown that raspberries and other antioxidant components may reduce the risk of breast, colorectal, and gastric cancer cells. Antioxidants, especially anthocyanin, may also reduce inflammation, and oxidative stress.

4. Purple or red grapes –

Grape varieties such as Purple and Red have been found to contain Vitamin C, Selenium, and Antioxidants, specifically Anthocyanins and Proanthocyanins. These antioxidants may be beneficial in protecting individuals from cardiovascular disease or cancer.

6. Red cabbage –

Cabbage, also known as red cabbage or purple cabbage, is packed with nutrients and antioxidants. It’s got four times more antioxidants than regular cooked cabbage, thanks to its anthocyanin compounds that give it its color. FRAP analysis shows that red cabbage can provide up to two and a half milligrams of antioxidants in every 3.5 ounces. These antioxidants have been linked to a range of health benefits, like reducing inflammation, protecting heart health, managing diabetes, helping with weight control, and even reducing the risk of some cancers.

Artichokes is a tasty and healthy vegetable that is rich in nutrients, fiber, minerals, and antioxidants. It has been used in ancient times as a remedy for liver conditions such as jaundice, and FRAP analysis shows that artichokes have a high antioxidant content (4.7 mmol) and a low antioxidant content (3.5 mmol) per 100 g. Artichokes are particularly rich in an antioxidant called chlorogenic acid which may help protect against certain types of cancer and diabetes, as well as heart disease.

Studies have shown that eating artichokes regularly can be beneficial for gut and liver health, as well as lowering cholesterol levels. Depending on the method of cooking, cooking artichokes can increase the antioxidant content by 8-15 times, while frying them may decrease it. Eating artichokes regularly may help reduce a person’s risk of cardiovascular disease and related conditions.

8. Beetroot –

Beetroot is a great vegetable with an earthy flavor and lots of fiber, iron, and antioxidants. It’s especially packed with beta-carotene, which gives it its reddish color and has been linked to health benefits. Studies have shown that betalains can help reduce the risk of cancer in the colon and gut, as well as reduce free radicals. According to FRAP, beets have up to 3.5 grams of antioxidants in every 3.5 ounces. Plus, there are other compounds in beetroot that may help reduce inflammation, like beta-alanine capsules that can expressively relieve osteoarthritis and inflammation.

9. Spinach –

Kale is an abundant cruciferous vegetable that is rich in vitamins A, vitamin C and vitamin K, as well as a variety of antioxidants. Its popularity as a health food and a strong winter vegetable has made it one of the most sought-after greens on the planet. Kale is particularly rich in antioxidants, with some varieties containing nearly twice the amount of antioxidants as green kale. This is due to the presence of anthocyanin and other antioxidants that give kale its vibrant color. Additionally, kale is a great source of calcium, a mineral that is essential for bone health and other cellular functions.

11. Beans –

Beans are an excellent source of proteins, phytonutrients and dietary fiber that are low in calories and high in vitamins and minerals. They are also one of the top vegetable antioxidants that can help with regular bowel movements. According to FRAP analysis, green broad beans have up to 2mmol of antioxidants in every 3.5 ounces (100 g) of beans. However, some beans, such as pinto beans, contain a special type of antioxidant that has been linked to amazing health benefits. These benefits include reduced chronic inflammation, and suppression of cancer growth in breast tissue, bladder tissue, kidney tissue, and lung tissue. Because beans have so many potential health benefits, you should include them in your daily diet.

12. Broccoli –

Broccoli and leafy vegetables are packed with phenolics, which are a type of chemical produced by plants to resist oxidative stress. Phenolics play an important role in human health, as they are packed with antioxidants and have anti-cancer benefits that may help protect against diseases, inflammations, and allergies.

13. Potatoes –

Potatoes are rich in carbohydrates, vitamins and minerals. As a result, they have many health benefits, including a higher antioxidant content. The antioxidants found in potatoes may play a role in lowering blood pressure, cardiovascular disease, and cancer and neurodegenerative conditions.

C. Other foods

14. Dark chocolate –

The consumption of cocoa-rich products such as dark chocolate has been linked to a range of health benefits, including a reduced risk of heart disease, inflammation, and reduced risk of high blood pressure. Studies have indicated that dark chocolate may be more nutritious than regular chocolate due to its higher cocoa content, as well as its higher levels of minerals and antioxidants. The antioxidant content of dark chocolate is estimated to be up to 15 millimonoles (mmol), which is greater than that of blueberries or raspberries.

Furthermore, research has suggested that dark chocolate may increase the levels of HDL cholesterol, while preventing LDL cholesterol from oxidizing, which is detrimental to the heart. Furthermore, dark chocolate may have other health benefits, including improved cognition, reduced memory loss, and increased mood.

Whole oats are rich in antioxidants that may help reduce chronic inflammation associated with heart disease, diabetes, and other conditions. Oats are also considered to be a good food for weight loss. Oats have high soluble fiber levels, which allow them to absorb water easily. This helps to slow down digestion and make you feel fuller.

What are potential risks of taking Antioxidant supplements?
