Free radicals: It is the culprit who is responsible for ageing
« on: February 27, 2012, 05:44:45 PM »
No body of us want to be old. Our age will increase with the change of calender, our experience will be increased but not ageing. But it is not possible for the presence of Free radicals.

Lets know, what is Free radicals?


The process in which oxygen combines with another material is called oxidation. For instance, unprotected iron will turn to rust when oxidized, fruits will turn brown, and butter will become rancid. A similar process occurs in the body causing it to degenerate and age, and as we get older more oxidation occurs in the body.

When our cells are exposed to free radicals, this process of oxidisation occurs. Therefore, our aging process depends on our ability to protect our cells from oxidation. However, this is no easy task; we are exposed to free radicals every day, introduced to the body from toxic chemicals that are either breathed in or absorbed through the skin.

The body’s oxidative reaction occurs due to the exposure to environmental toxins that are present in the air we breathe, the water we drink, the food we eat and the household products we use. And it is these ‘free radicals’ that contribute to the oxidative reactions in the body and cause tissues to damage and can also affect memory and mood, wrinkling of the skin, hardening of the arteries, stiffening joints — the list goes on.

Exposure to environmental toxins dramatically increases the level of free radicals in the body, sometimes beyond what our body can fight on its own. The human body is capable of handling and neutralising a certain amount, but when the system is overloaded the body’s normal ability to cope with them is compromised and become susceptible to premature aging and disease.
Free radicals can be found in the following:

    Junk food
    Refined foods, such as sugar and white flour
    Processed foods (canned, frozen and ready made meals)
    Colourings, preservatives and food additives
    Chemotherapy or radiation exposure (X-rays, TV and computer monitors)
    Drugs and medications
    Coffee and tea
    Hydrogenated and saturated fat (margarine and oils)
    Fizzy drinks
    Exposure to heat or cold
    Household chemicals
    Tap water
    Cigarette smoke and alcohol

So we have to do some things for these free radicals.............
