12 Jul Free radicals
The body is under constant attack from 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, according to the Huntington’s Outreach Project for Education at Stanford University. These substances include fried foods, alcohol, tobacco smoke, pesticides, and air pollutants.
