The importance of antioxidants in our daily life normal cell life processes involve the release of radical free to combat viruses, kill cancer cells and destroy the bacteria. These processes are called oxidation. These processes must be very precise and of short duration. If it is not, is produce significant collateral damage to the surrounding tissues. The antioxidants present in blood and fluids from tissues, cells maintain controlled oxidative processes and help prevent collateral damage to the surrounding healthy tissues. Recent research has shown that the deficit of antioxidants during inflammatory chronic conditions such as pollution, smoke, light from the Sun and toxins causes an accelerated and exaggerated response oxidative, causing more inflammation and leads to many degenerative diseases and accelerated aging. Obesity, immune dysfunction, cardiovascular disease, the decline in cognitive function and cancer share these characteristics of uncontrolled oxidation, by what research to identify antioxidants in an effective way and to quantify their abilities has been the focus of the food industry. Tests has focused on trials of the oxidative chemical reactions in liquid or Fluid nutrient fluid body, or in trials in humans in search of concrete results with nutritional supplementation.
The ORAC (oxygen radical absorbance capacity) test has been used as a relatively simple and inexpensive method to test body fluids or extracts of nutrients. However, this method of biochemical reaction not always corresponds to clinical outcomes since it is only a laboratory test or try biochemistry. Obviously, there are more complex mechanisms that would show a greater benefit than the limited series of chemical reactions measured by ORAC. In addition, the solvents used in the extraction of a nutritional agent for ORAC testing they can alter the chemical reactions that are measured, i.e., can give a misleading result. In recent years of nutrition research, cell-based tests have become a new technology to evaluate these complex mechanisms of biological protection.
