What Are Antioxidants?

Antioxidants, as implied in its name, are nutrients and enzymes that counteract or prevent cell damages. They are called antioxidants as they help fight or prevent cell damage caused by oxidants. They play a huge role in minimizing the risk of developing chronic diseases like heart disease, cancer, Alzheimer’s disease, stroke, cataracts and Rheumatoid arthritis.

Antioxidants are found in many plant-based foods such as vegetables, fruits, tea, coffee, chocolate and wine. There are a lot of antioxidants compound, however, the most popular are resveratrol (found in wine), flavanols (found in chocolate), lycopene (found in tomatoes), catechins and vitamins C, A (beta-carotene) and E.

Antioxidants have three primary types and they are:

  • Phyto-chemicals – This is a type of antioxidants that is made by plants to give themselves protection from free radicals. Flavonoids, carotenoids, polyphenols, Allyl sulphides, etc. belong to this. It is said that people who have diet composed of foods that are rich in phytochemicals also get the same benefits from the antioxidant properties of the plant.

  • Enzymes – These are manufactured by our body. They are made from minerals and proteins in the food that we eat, which include glutathione peroxidase, superoxide dismutase, catalases and glutathione reductase.

  • Vitamins – Since our body is not capable of producing vitamins, it is important that our diet contains antioxidant vitamins such as vitamins C, A, E, beta-carotene and folic acid.

Benefits of Antioxidants

Now that we have identified "what are antioxidants" and their common types, what can it do to our body aside from protecting our cells from the damage of oxidants?

Antioxidants and free radicals

Our body naturally produces free radicals which are bad for our health, however, in most cases, the natural antioxidants are outnumbered by the free radicals. So antioxidants are needed to help the body in balancing and removing free radicals from our bloodstream.


Antioxidants and Skin Health

Our skin has high risk of being damaged if it’s exposed to high levels of ultraviolet light. It results to skin diseases and impurities such as premature aging, photodermatoses and even skin cancer. One of the most powerful antioxidant that is known for its ability in protecting our skin is astaxanthin. Combine it with vitamin E and beta-carotene for a more potent skin protection.


Antioxidants and Immune System

We are exposed to thousands of bacteria and germs every day but thanks to our immune system, it protects us from illness and diseases caused by these particles. It is important that we have a strong immune system to be at the top of our health. It’s hard though to boost our immune system when we are constantly in contact with free radicals. Then antioxidants help a lot. What are antioxidants’ roles in boosting your immune system exactly?

Vitamin C – It helps in the production of antibodies and white blood cells. It also prevents viruses from entering your body by increasing the production of interferon.

Vitamin E – It increases the production of natural killer cells. It also helps in manufacturing of B cells which makes antibodies. Vitamin E can also reverse the natural decline of immune system’s function associated with aging.

Carotenoid – It increases the production of helper T-cells and natural killer cells.

Bioflavonoid – It helps prevent germs from entering your body.
