Fact-Checked

Humans need a balanced diet for survival. Hence, an assortment of essential micronutrients is needed. An example of one such essential requirement is antioxidants.

Antioxidants are naturally produced by the body to fight free radical damage. Free radicals are harmful compounds that are linked to many diseases, such as cancer and heart disease. Antioxidants help keep free radicals at bay.

Besides the antioxidants your body generates, they can also be found in food and supplements. Some people prefer supplements over foods.

But it is important to remember that there is no need for supplements when dietary intake is sufficient.

In this article, we will discuss some great food sources of antioxidants. Adding these in your daily meals will enrich your diet with numerous nutrients.

Best Antioxidant Foods

Foods Rich In Antioxidants

Generally, low-carb diets and non-veg foods may not be the ideal options for fetching maximum antioxidants. Many of the foods restricted in a low-carb diet have high amounts of antioxidants.

Choose and plan your diet accordingly so that you don’t deprive the body of needed nutrition.

Below is a list of antioxidant-rich foods. You can include any of these according to your needs, preferences and diet plans.

  1. Spinach

    Spinach is one of the best and healthiest greens. It is a staple in numerous healthy and delicious recipes such as smoothies, and salads. Even a small serving of 100 g can provide vitamin A, vitamin C and iron.

    Roughly, 100 g of spinach contains 0.9 mmol of antioxidants, including[1] lutein, carotenoids, beta carotene, and zeaxanthin. This antioxidant-rich food helps promote eye health and prevent macular damage.

  2. Beans

    Beans are available in numerous varieties and are packed[2] with antioxidants, proteins and carbohydrates. The dietary fiber present in beans keeps bowel movements regulated.

    Green board beans are one of the richest bean sources of antioxidants. They contain around 2 mmol of antioxidants per 100 g.

    Kidney beans are also a high octane source of antioxidants. They also contain folate, vitamin C, selenium, zinc and calcium.

    When beans are combined with grains, they act as complete proteins. Including them in the diet is a great way of getting closer to your required nutritional requirements.

  3. Nuts

    Although they might be small in size, the benefits of nuts are infinite. Nuts are a great source[3] of fiber, proteins, fats, and very importantly, antioxidants.

    Almonds and walnuts are the go-to options while chestnuts and pecans are great choices as well. Both the nuts are low in sodium.

    Almonds have a good amount of vitamin E, which acts as an antioxidant helping in cell membrane formation.

    Just 28.4 g of almonds contain about 7.27 mg of vitamin E. Walnuts have more[4] antioxidants than most other nuts. This is due to the presence of vitamin E and melatonin.

    Both almonds and walnuts have polyphenols. This helps prevent oxidative damage.

  4. Berries

    Berries of different sizes, shapes and vibrant colours are mesmerizing, but they have more to offer than just variety. With varying tastes, they have amazing benefits[5] too.

    Many types of berries are rich in antioxidants, including,

    • Cranberries- Cranberries are a great companion for women. They help in maintaining healthy vaginal pH. They provide vitamin C, K and magnesium. Polynutritients present in them are good antioxidants. They may prove to be useful in cancer prevention.
    • Raspberries- They are a good source of ellagic acid. It acts as an antioxidant. Additionally, they provide vitamins and fibers. Raspberries may help in preventing the growth of tumour-causing cells. They provide nearly 4 mmol antioxidants per 100g.
    • Goji Berries- They are a perfect source of antioxidants. The combination of lycopene and beta carotene present in them makes them very effective for eyes, skin and hair.
      They also boost immunity which includes[6] resistance toward unwanted organisms in the body. They may provide 4.3 mmol antioxidants per 100g.
    • Gooseberries- Like all the other berries mentioned above, they have health benefits too. They have phytonutrients that act as antioxidants. The Indian gooseberry[7] popularly known as Amla, is a great source too.
      Ayurvedic medicine, a type of alternative medicine in India, and traditional uses highlight its role as an antioxidant too. It is good for skin, digestion, eyes, hair and a lot more. Its biggest role is in the detoxification of blood. This aids in the prevention of oxidative damage.

  5. Fruits Rich In Vitamin C

    Fruits are effortlessly rich in vitamins. One of these is vitamin C. This vitamin is a strong[8] antioxidant.

    Popular fruits like peaches, oranges and many more have vitamin C in addition to all the other nutrients they hold.

    Dark chocolate is very helpful for skin as well. It adds plumpiness to the face and keeps you hydrated. Dark chocolate with 70 percent cocoa content or more is best for healthy consumption. It may provide 15mmol antioxidants per 100g.

  8. Hen Eggs

    Even though plant foods are better sources of antioxidants, eggs have their benefits. If you love fluffy omelettes and cannot follow an all veggies and fruits diet, this one’s for you.

    The yolk of hen eggs has lutein and zeaxanthin. If you are looking to increase[12] antioxidant intake, try eating whole eggs and not just egg white.

What Are Free Radicals?

They are unstable molecules. They either donate or gain an electron to attain stability. They are produced in our body during activities like exercise and inflammation.

Some external sources like air pollution, smoking, vaping and x-rays are responsible for the production of free radicals.

The Role Of Antioxidants On Free Radicals

Free radicals are responsible for numerous health problems. They may target brain functioning and cause Alzheimer’s disease. They are not safe for the skin and speed up the ageing process.

They may increase blood cholesterol levels. This can be a serious threat to the heart. Additionally, they affect the coded information in DNA. Cancer is another problem often linked to free radical damage.

To counter the production of free radicals, our body produces antioxidants. They are a natural defence[39] against free radical damage. Therefore, they are also included in the diet for reaping maximum benefits.

They may effectively reduce cell damage caused by free radicals. However, they alone cannot prevent the damage, especially in the case where external sources like smoking are involved.

Some examples of antioxidants are:

  • vitamin E
  • Vitamin A
  • Lycopene
  • omega-3 fatty acids
  • omega-6 fatty acids
  • beta-carotene
  • Selenium
  • Lutein
  • Zeaxanthin
  • Carotenoids

Conclusion

Antioxidants are essential for human survival. They are produced by our body to fight free radical damage. These radicals are produced within the body. Some external sources like smoking, pollution and X-rays are also responsible.

They can cause cancer, Alzheimer’s disease, heart problems and ageing of the skin. Antioxidants may prove to be useful in preventing these diseases beforehand.

Including antioxidants in the diet help in improving one’s health. Plant sources like fruits and vegetables provide enough antioxidants. Some of them are seeds, walnuts, spinach, kale, red cabbage, berries etc.

However, some non-vegan sources like eggs and fatty fish are also healthy options. They are packed with antioxidants too.

According to some researchers, a person needs 3000-5000 ORAC units ( Oxidative Radical Absorbance Capacity) per day for a healthy life.

Do not take a surplus amount as it is either excreted by kidneys or causes damage to the body.
