Everything That You Need To Know About Antioxidants

You must have heard a lot about antioxidants... It has become a health buzzword; often comes up frequently in discussions about nutrition, wellbeing, good health, and fitness. But beyond the entire buzz, what are antioxidants? How important are they? What are their health benefits? And why it is very important nowadays to take the antioxidants in our daily diet?


To understand antioxidants, you first need to know about free radicals.

Free radicals are molecules/atoms having an unpaired electron. They are basically single and eagerly ready to mingle…so; always searching out another electron to pair up. This makes them highly reactive.

Free radicals cause damage to important components of cells such as Cell DNA and cell membranes by stealing their electrons through a process called oxidation (That is free radical damage is also called "oxidative damage"). These damaged cells lose their ability to function normally, which may cause cell death hence is associated with early signs of aging, cancer, Alzheimer's, and many other degenerative diseases.

Few free- radicals are part of our body's natural defense system and our body naturally repairs the damage caused by them. But when there are too many of them…our body is not able to repair the natural repair damage anymore.

Free- radical Damage Includes:

  • Deterioration of the eye lens contributes to blindness and cataract.
  • Poor Immunity and immune response.
  • Inflammation of the joints (arthritis)
  • Damage to nerve cells in the brain contributes to Parkinson’s and Alzheimer’s disease
  • Accelerated the aging process
  • Increased risk of coronary heart disease, since free radicals increase LDL (So-called bad cholesterol).
  • Increased risk of certain cancers, triggered by damaged cell DNA.

External factors which trigger the free- radical’s formation are poor diet, alcohol, tobacco, smoke, air pollutants, exposure to chemicals like pesticides/drugs and UV exposure and many more. In fact, healthy act like "Exercising" also trigger the free-radicals’ formation in our body.

What is the solution then? Should I Stop Exercising?

The Solution is Antioxidants – The Super Man!

Adding more Antioxidants rich foods in your diet can save you from free-radical damage.

Antioxidants are stable molecules containing paired electron and can share an electron to the free radical, thus stabilizing it. Antioxidants are supplement foods that neutralize and remove the free radicals from the bloodstream and this prevents free radicals from attacking other cells and triggering the degenerating diseases.

"Free radicals are like the drunken unstable friend who shows up to the party and starts breaking things. Whereas, an antioxidant is like a well-wisher who takes care of that drunken friend and calms her down. Pointless to say, without the presence of well-wisher (antioxidants), free radicals could had ruin the party"


What all other benefits of Antioxidants?

  • Sunburn protection – Vit-C, Vit-E, and selenium antioxidants have been proven to decrease the effect of the sun on the skin and actually prevent further damage.
  • Anti-Aging - Prevent the skin cells damage, also preserves tissue elasticity and slows down the aging and hardening of tissues associated with oxidation.
  • Cardiovascular Disease – Antioxidants prevent heart disease & stroke by raising HDL (so-called good cholesterol).
  • Reduces the risk of cancer – Studies have found that people who eat more fruits and veggies have a lower risk of cancer. It’s a delicious way to cut your cancer risk!
  • Reduces diabetes and its complications – High blood sugar creates free radicals, so everyone with diabetes or pre-diabetes could benefit from a nice hit of extra antioxidants.
  • Defends against dementia – Research has found that people who consumed the most vitamin C & E cut their risk of dementia by up to 50%!
  • Protect our eyes – against macular degeneration and cataracts. Vitamins C & E and beta-carotene are mainly involving in eye protection.
  • Immunity Support – Powerful antioxidants in spirulina have been found to boost the immune system while also protecting cell membranes.
  • Helps to eradicate the effects of air pollution – Research has found that Vitamin C is an important nutrient to protect the lungs from pollution, especially if one suffers from asthma or COPD.
  • Reduces inflammation – Help to reduce as well as repair cells injured by inflammation. Where to find antioxidants?

Antioxidants are naturally occurring compounds in most foods. Our body also makes it and is part of the body’s natural defense system against cellular damage. But, as we age, the ability to produce antioxidants declines.

To maintain the balance, a continual supply of dietary antioxidants is necessary.

Plant foods are rich sources of nutrients as well as antioxidants. They are most plentiful in fruits and berries and green vegetables, as well as other foods including nuts, oilseeds, legumes, pulses, and whole-grains.
