What are the free radicals ? Evidences to show by scientists that the free
radicals are the main reason causing the body aging of human being.
The free radical means an atom or group of atoms with at least one
unpaired electron; in the body it is usually an oxygen molecule that has
lost an electron and will stabilize itself by stealing an electron from a
nearby molecule. " In the body free radicals are high-energy particles
that ricochet wildly and damage cells" .
As early as 1954, Professor Harman ,working as a teacher in the school
of medicine of Abraham Lincoln University of United States, has been put
forward, but was regarded as a fallacy, never received much attention
until twenty years later. In 1995, Professor Harman was nominated for the
Nobel Prize in medicine.
The relation between free radicals and body aging
What are the free radicals ?
When a variety plex metabolism using oxygen are carried out inside the human body, a free radical that could be a atom or molecule is produced at the same time in which an electron is ejected from the atom or molecule, leaving a positively charged ion (free radical). The free radical is unstable and easy to fetch an electron from others to make itself stable.

Under what circumstances?
Easily lead to free radicals?
It is well known that the people needs to breathe in order to survive, the food
will be converted into energy via oxidation inside the cells of the human
body.
However, a possible condition of an electron ejected from the atom or
molecule inside the human body will sometimes be happening at the process
of electrons delivery throughout the cells durin
