The Tin Man in the Wizard of Oz couldn’t move due to oxidation. Likewise, our health can suffer due to oxidative stress, and we need something other than an oil can to keep us in good repair!
We’ve all seen what oxidation does to a piece of metal . . corrosion and rust! Our bodies are under the same kind of stress. Even though oxygen is essential for life, it can generate damaging by-products during normal cellular metabolism. These by-products are called free radicals.
The oxidation process is necessary, but it leaves behind free radicals, oxidized molecules that are short of electrons. These molecules are unstable and agitated. They stay unstable and short of electrons until they seize new electrons to replace the missing ones. They prowl throughout our bodies taking electrons from our cells, even our most vital ones like electron-rich DNA.
When free radicals steal electrons away from our DNA it no longer functions properly. DNA stores our genetic information and controls the reproduction of all new cells, including the cells of our organs, heart, brain and other tissues which are vital to our health.
Left uncontrolled, free radicals may cause in excess of 50 health problems including mutation of new cells; damage to vision; faster aging of skin, organs, and bones; damage to heart and blood vessels; damage to the nervous system and brain cells; enzyme malfunction; cancer; and a weak immune system.
Various things ramp up our metabolic activity and consequently increase our body’s manufacturing of free radicals:
- Strenuous physical activity
- Mental stress, depression, and repeated anxiety
- Toxic industrial chemicals in our water, air, food, and beverages
We have in our blood streams 300 – 500 toxins, the majority of which didn’t exist prior to World War II. This is regardless of what section of the country we live in. One researcher tested people around America and found that 100% of the persons tested had 100% of the toxins tested for.
Our drinking water has been contaminated by chemical fertilizer runoff, medicines flushed down our toilets, and pollution from manufacturing facilities.
Perhaps the primary way to protect ourselves from free radical damage is eating foods high in antioxidants. Antioxidants easily give away their electrons to “hungry” electron deficient free radicals. The way that antioxidants work is that they either bind to the free radicals and convert them into harmless compounds or by repairing cellular damage.
Antioxidants found in what we eat include vitamin C, vitamin E, selenium, and the carotenoids. Our bodies can also produce antioxidants. However, the antioxidant content of our modern diet has been severely decreased due to soil depletion, “green harvesting”, and today’s farming techniques. Any antioxidant nutrients in fruits and vegetables that survive our modern-day growth and harvesting methods then suffer due to the cooking, processing, preserving, and packaging common today.
Thus to make sure that our bodies get enough antioxidants it is necessary that we eat foods high in antioxidants and to take a reliable antioxidant supplement in our daily diet. This pdf document, A comparative list of antioxidants, shows the free radical protection provided by each of 91 different antioxidant products based on their ORACo value. ORAC is an acronym for Oxygen Radical Absorption Capacity. The original ORAC assay was a measurement for only water-soluble antioxidant activity. ORACo assays both fat and water-soluble antioxidant activity.
