Pay attention and listen very carefully
What Are Free Radicals?
Oxidative stress occurs when an oxygen molecule splits into single atoms with unpaired electrons, which are called free radicals.
The body is under constant attack free oxidative stress. Oxygen in the body splits into single atoms with unpaired electrons. Electrons like to be in pairs, so these atoms, called free radicals, scavenge the body to seek out other electrons so they can become a pair. This causes damage to cells, proteins and DNA.
Free radicals are associated with human disease, including cancer, atherosclerosis, Alzheimer's disease, Parkinson's disease and many others. They also may have a link to aging, which has been defined as a gradual accumulation of free-radical damage.
Substances that generate free radicals can be found in the food we eat, the medicines we take, the air we breathe and the water we drink, include fried foods, alcohol, to***co smoke, pesticides and air pollutants.
Free radicals are the natural byproducts of chemical processes, such as metabolism.
Yet, free radicals are essential to life and the body's ability to turn air and food into chemical energy depends on a chain reaction of free radicals. Free radicals are also a crucial part of the immune system, floating through the veins and attacking foreign invaders.
The danger of free radicals
Once free radicals are formed, a chain reaction can occur. The first free radical pulls an electron from a molecule, which destabilizes the molecule and turns it into a free radical. That molecule then takes an electron from another molecule, destabilizing it and turning it into a free radical. This domino effect can eventually disrupt and damage the whole cell, and that is called cancer and also one of the things that can cause prostate cancer, breast cancer, skin cancer.
