Antioxidant Mechanism of Resveratrol - Can We Get This Through the Food We Eat?

The antioxidant mechanism of resveratrol is still being studied.
There are several theories concerning how it works and what function it performs in the cells of the human body.
Antioxidants of all kinds are necessary for life, but they vary in the effects that they have and even where they are found.
The concentration of antioxidants within the human body varies.
Some antioxidants are found in the bloodstream.
Others are present in the cells and tissues.
Some are produced within the human body.
Others must be obtained through dietary sources.
The question that some of us have is whether the food that we eat is nutritious enough to support the body's ability to produce these antioxidants.
In most cases, the answer is "not".
It's not only that many common diets have low nutritional value; most foods are not as nutritious as they were at one time.
Fruits and vegetables are harvested before they ripen, which is necessary for mass distribution, but also means that the amount of antioxidants and other nutrients present in the food will be lower.
Researchers trying to unravel the antioxidant mechanism of resveratrol have found that the nutrient protects healthy cells and prolongs their life, while fighting cancer cells and triggering reactions that cause their death.
It improves the function of the mitochondria, within the cells, and increases the activity of MnSOD, which reduces hydrogen peroxide.
Hydrogen peroxide is formed within the cells during respiration and although it is not particularly toxic, it can trigger free radical chain reactions that can damage the cellular membrane and other cellular components.
One problem with explaining the antioxidant mechanism of resveratrol within the human body has to do with its bio-availability.
Most nutrients are soluble in either water or fat.
Vitamin C and glutathione are examples of water-soluble antioxidants.
Vitamin A, E and coenzyme Q10 are fat soluble.
Resveratrol is only slightly dissolved by water.
Neither is it well absorbed when consumed through dietary sources.
Drinking wine does not greatly increase the trans-resveratrol found in the blood stream.
Supplements with an enteric coating provide a greater increase in the blood's trans-resveratrol content.
In order to get any benefit from supplementation, the manufacturer must protect the nutrient with an enteric coating.
Only the best ones do.
Another part of the antioxidant mechanism of resveratrol has to do with its ability to break down heavy metals that get stored in the bodily organs.
These toxic substances cause damage over time that leads to high blood pressure and neuro-degenerative diseases like Alzheimer's.
It also has natural ant-inflammatory activity and chronic inflammation is believed to play a big role in age-related diseases of all kinds.
If you are considering supplementation, let me suggest a multi-nutritional supplement that includes the common vitamins and minerals, as well as the less common ones.
Botanical and herbal extracts are a good choice, as well.
We may not yet understand the antioxidant mechanism of resveratrol.
We do know that it's good for us.
But, it is only one of many nutrients that our body's need, everyday.
