Healthy Foods High in Antioxidants and their Benefits

What are antioxidants? Quick Scoop

  • 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.
  • The sources of antioxidants can be natural or artificial. Certain plant-based foods are thought to be rich in antioxidants. Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient.
  • Dietary supplements provide antioxidants in the form of vitamins A, C and E, carotenoids such as beta-carotene, lutein and zeaxanthin, as well as minerals like zinc, and nutrients like CoQ10.

Why are Antioxidants so Important?

Healthy Foods High in Antioxidants and their Benefits


Antioxidants are molecules that fight free radicals in your body which is very important for maintaining overall health and prevent aging and diseases.

Your body generates free radicals that can cause harm if their levels become too high in your body. Free radicals are linked to many illnesses like cancer, diabetes, heart disease and high blood pressure. We cannot escape free radicals because they are created naturally when we breathe, exercise, and convert food to energy.

Antioxidants are compounds that help neutralize free radicals. The body also makes its own antioxidants, but the level of antioxidants depends entirely on the food we eat. Consuming greater amounts of antioxidant-rich foods might help to protect against and fight many diseases.

Healthy Foods High on Antioxidants

The best way to obtain antioxidants is through food. Fortunately, there is a big variety of antioxidant rich foods. Scientists use several tests to measure the antioxidant level.

The best tests is the FRAP (ferric reducing ability of plasma) analysis. It measures the antioxidant value of foods by how well they can neutralize a specific free radicals.

Here is the list of healthy foods that are high on antioxidants.

  1. Dark Chocolate

Which Vitamins are Antioxidants

Ideally, if you follow balanced diet there is no need on adding antioxidant supplements. In reality many people have vitamin and antioxidant deficiency due to poor diet and consumption of processed foods. Dietary supplements may help increase antioxidant intake.

Below is the list of some vital nutrients for you to ensure your daily antioxidant intake.

  • Vitamin A

Vitamin A can be effective antioxidant and is essential in supporting immune system and eye function.

  • Vitamin C

Vitamin C plays an essential role in shaping and protecting our connective tissue and supporting your immune system. Studies show that antioxidant supplements with vitamin C can help prevent cancer in many ways. Also vitamin C fights the peroxidation of lipids, which have been linked to degeneration and aging.

  • Vitamin E

Vitamin E is the major component in the cell antioxidant defense system. It has been shown to be effective against cancer, ageing, arthritis, cataracts and etc.

  • Alpha-lipoic acid

Alpha-lipoic acid is an antioxdant and it might provide protection to the brain and also be helpful in certain liver diseases. Alpha-lipoic acid can effectively combine vitamins C and E as part of the first line of defense against free radicals.

  • Ellagic acid

Ellagic acid is a plant polyphenol and a highly effective antioxidant that inhibits          hydroxyl radicals.

  • Coenzyme Q10

Coenzyme Q10 (CoQ10), or ubiquinone, helps support heart health and          provides antioxidant support to protect cells from oxidative stress. CoQ10 decreases in the body as people age or develop certain diseases (such as other heart conditions, Parkinson’s disease, and asthma). CoQ10 helps fight those diseases and slow down the effects of aging.

  • Selenium

Selenium supports the healthy functioning of the immune system, acts as a powerful antioxidant, and is essential for good thyroid health.

  • Zinc

Zinc is essential mineral that supports healthy immune system. It is also important for normal growth and development.
