Effects Of Free Radicals - Premature Aging Is Caused By Free Radical Damage To Cells
By Andy Kahn

Free radicals cause massive damage to cell membranes. Any organism and organ system contains billions and billions of cells and each cell has to communicate with other cells for effective functioning of the organ system. While human being is an organism the organ systems are brain, eye, liver, pancreas, heart etc. Cell membranes are also involved in importing necessary nutrients from other cells and exporting waste products. Free radicals also damage cell's nucleic acid, DNA, and mitochondria.

Mitochondrion is the power house of the cell. This where the energy metabolism takes place, furnishing the energy needed by cells and tissues to properly function. Deficits in energy metabolism cause greater fatigue and pain, and cause organs to function at a reduced capacity.

The process of free-radical damage and reduced energy production occurs in a self-perpetuating cycle. Damaged mitochondria produce less energy and more stress. Stressors in the body are one of the major causes of free radical production. This endless cycle of stressors and free radicals cause continuous damage to mitochondria.

Till the age of 30 these subtle free radical attacks show little outward effect. After the age of 30 (and lower for women) the exponential nature of the damage begins to take its toll and energy production declines below levels necessary for good health.

Studies indicate that many people with a shorter life span have higher than normal oxidative stress. Brain tissues from Alzheimer's patients, for example, have unusually high levels of mitochondrial DNA damage. Tissue samples from individuals with heart disease reveal similar damage. Free-radical damage is most pronounced in oxygen-rich organs like eyes, brain, liver, heart, lungs, kidneys, and blood.
