Antioxidants Facts

What exactly is an antioxidant?

By definition, it is a chemical substances, found in nature or made in the laboratory, that can protect against oxidation damage caused by free radicals which harms or kills cells.

Where do free radicals come from?

Free radicals are left-over stuff (byproducts) of metabolism that uses oxygen in the process.

And pretty much every cell in your body uses oxygen for metabolism. They are everywhere since all earthly life uses oxygen for metabolism.

What do these free-radicals do to our body and cells?

Free-radicals are highly reactive. When they come in contact with cell membranes or other cellular structures, they chemically react with them and cause a certain amount of damage.

The free-radicals made during metabolism, if not removed, are strongly suspected to cause many diseases such as heart disease, premature aging, Alzheimer's disease, cancer, diabetes, Parkinson's disease and cataracts.

Antioxidant - All the Different Types

Types Antioxidants Facts and Food Sources
Vitamin C This is the most well known and widely used antioxidant.

It can boost the immune system, help with symptoms of the common cold, protect the blood vessel against oxidative damage and protect against damage caused by smoking.

There is evidence from research studies, that it doesn't seem to help protect against cancer.

Vitamin E This is a potent antioxidant that enhances the immune system and may help you live longer.
Bioflavonoids See our article Health Benefits of Bioflavonoids to discover this group of antioxidants.

There are over 5,000 different compounds found in this group!

Carotenoids This group includes beta carotene, lycopene and lutein. Studies show that carotenoids can help prevent heart disease, boost the immune system and help prevent certain types of cancer.

Beta carotene are known to be helpful in protecting a smoker's lung.

Lutein is routinely recommended by doctors for people who suffer from eye problems such as macular degeneration (which leads to blindness).

As well, studies show that lycopene helps prevent prostate cancer. Foods that contain carotenoids include tomatoes, spinach, carrots and pumpkins.

Amino Acids There are several amino acids that possess good antioxidant benefits.

They include glutathione, cysteine and alpha lipoic acid (ALA).
