Free Radical
Our normal metabolism in the body created side products, and some of these side products are harmful to our body, for example, free radical, free radicals are atom or molecule which have 1 unpaired electron on their orbital, and due to this unpaired, the electron tends to snatch over the electrons of other molecule, and this eventually will target the most vulnerable side of our body, the human cells.
The cells are responsible for our daily work such as providing us energies, synthesis of our body proteins, the damaged cells lead to reduce performance of our daily activities, prolonged damaged of the cells lead to degenerative diseases such as Alzheimer disease, Parkinson disease, and other degenerative diseases. Several researches had shown that free radical are correlated with the aging of our human being too.
What can our body do to counter the effect of free radical?
The answer is Anti oxidant, which refers to the vitamins, minerals, phytochemicals (plant chemicals) and other natural compounds that protect your body from free radicals. the free radical acts by providing additional electron to the free radical so that the free radicals attack the anti oxidant instead of attacking our cells and damage the important cell component.
Basically there are two types of anti oxidant, fat soluble anti oxidant and water soluble anti oxidant, each of the anti oxidant have its own specialty, for examples:vitamin c is water soluble and is therefore the best antioxidant to target free radicals within the blood and plasma. Vitamin E and coenzyme Q-10 are fat soluble and they are the best anti oxidant within the cell membrane. Glutathione is the best anti oxidant within the cell itself. Member of these anti oxidant network rescue one another when they become oxidized by free radicals.
Sources of antioxidant in our dietary:
Vitamin C – Kiwifruits, orange, lemon, grapefruits, papaya
Vitamin E – Sunflower oil, avocados, wheat germ oil
Coenzyme Q-10 – Fish (salmon, sardine), Heart of animal, soybean oil, grapeseed oil, sunflower oil
Glutathione – Asparagus, spinach, thistle milk, garlic (all these serve as glutathione booster as it is synthesized naturally in our body)
Lipoic acid – dark green leafy vegetables, including spinach and collard greens; broccoli; animal foods such as beef steak; and organ meats such as calf’s liver
