We need antioxidants because many free radical forming substances expose to the body. The external factors such as cigarette smoke (even if we are not active smokers), air pollution and internal factor such as excessive alcohol consumption can lead to free radicals production.

A free radical is any atom or molecule that has a single unpaired electron in an outer shell. The free radical theory of aging states that organism age because cells accumulate free radical damage over time. The theory was proposed first time by Denham Harman in the 1950s.
A balance between free radicals and antioxidants is necessary for proper physiological function. If the generation of free radicals exceeds the protective effects of antioxidants, this can cause oxidative damage which accumulates during our lifetime and has been implicated in aging and age-dependent diseases such as cardiovascular disease, cancer, diabetes, arthritis, macular degeneration, Alzheimer’s disease and other chronic condition.
What Is An Antioxidant?
An antioxidant is a molecule that inhibits the oxidation of other molecules. Antioxidants are nutrients that help protect our cells against oxidative stress from the damage caused by free radicals. Oxidation is a chemical process which involves the transfer of electrons or hydrogen-producing harmful free radicals in the body. Oxidation leads to a chain reaction that may damage cells.
Antioxidants help reduce the accumulation of free radicals in our body. They help to stop the damage done by free radicals and therefore may be effective in reducing the risk of diseases. Antioxidants reduce oxidative stress by neutralizing free radicals – unstable atoms that have an unpaired electron in their outermost shell, almost like a knife without a sheath. The antioxidants act to sheathe the knife, binding with the unstable electron and stopping it from attacking other cells.
The other name is micronutrient or vitamin. Human needs more than 50 micronutrients every day to keep the optimum health. Healthy aging involves the interaction among genes, the environment, and lifestyles.
The Most Modifiable Lifestyles Factors are:
- physical activity or exercise, and
- healthy diet

What Antioxidants Do To Protect The Body Cells?
Antioxidants help stop oxidation reaction by giving away one of their electrons to make free radicals stable, without making themselves unstable. Antioxidants neutralize free radicals by donating one of their own electrons.

ORAC Value / ORAC SCORE: Antioxidant Value of Foods and Beverages
The antioxidant values of foods are expressed in ORAC ( Oxygen Radical Absorbance Capacity ) units, a unit of measurement for antioxidant content which was originally developed by National Institute on Aging ( NIA ) at the National Institutes of Health ( NIH ) in Baltimore. ORAC units measure the antioxidant capacity of foods. Potentially the higher, the better.
The ORAC value of given food will vary due to growing conditions, processing conditions, specific variety and others. We can know the ORAC Value of various foods by searching here.
Here Is The List Of Top 10 Powerful Antioxidants:
Clove, Ground, 314,446 µmol TE/100g (micromol Trolox Equivalent per 100 grams).

We can chew clove like chew a candy, add it in smoothies recipes, or add it in cookies.
Adding more herbs and spices to our diet greatly increases the variety of antioxidants we get from our food.

Cinnamon improves insulin sensitivity so that it has a regulatory role in blood glucose level and lipid and it may also exert a blood glucose-suppressing effect.
- Antiseptic and Local Anesthetic
Eugenol in cinnamon gives local anesthetic and antiseptic properties, hence used in the dental and gum treatment procedures.
Various studies have indicated that cinnamaldehyde in cinnamon inhibits the activation of inflammation causing factor such as arachidonic acids.
Cinnamon is externally used as a rubefacient, a substance for topical application that produces redness of the skin e.g by causing dilation of the capillaries and an increase in blood circulation. It is also employed to counteract the sting of poisonous insects.
- Carminative, Anti-flatulent
An anti-flatulent agent is a drug used for alleviating or preventing of excessive intestinal gas.

We should understand that antioxidants are definitely not a treatment for cancer. The research is only suggesting that having less oxidative stress in life might prevent some occurrences of cancer before they occur, not after someone already has it.
The elderly, especially people over 40 years old whose have bigger health risks, should be encouraged to consume a diet rich in antioxidants because there are many pieces of evidence that such a diet in combination with a healthy lifestyle lower the mortality rate by more than 50% in the 70-90 years old (Knoops et al 2004).
