Resveratrol Supplements: or Just Polish Off the Merlot |

The popularity of the Mediterranean Diet and it's apparent impact on longevity has led to research into the substance resveratrol, an ingredient found in red wine and a diet staple in the Mediterranean culture.
After extensive experimentation, doctors have concluded that resveratrol demonstrates the ability to reverse the effects of obesity in mice. In addition, they observed that mice placed on a diet of resveratrol supplements also exhibited higher endurance levels and longer lifespans than mice on a non-supplemented diet.
In a controlled test environment, ordinary mice will normally run approximately one kilometer on a treadmill before collapsing in exhaustion. However, mice that have been given a resveratrol supplement will run twice as far before showing evidence of tiring. In addition, subsequent tests also show that the mice on the resveratrol program demonstrate heightened muscle control and strength and have a significantly reduced resting heart rate when compared to the ordinary mice.

The Hidden Health Benefits of Red Wine - Resveratrol |
|
|
|
|
There has been a long standing debate on the health benefits of consuming moderate amounts of alcohol. Specifically in regards to red wine, it may not be the alcohol that is gaining so much attention as the resveratrol that is in the red wine.
While resveratrol can be found in plants such as peanuts, mulberries, eucalyptus, spruce, and lily, resveratrol is most abundant in grapes used to make wine. Vitis vinifera, muscadine, and labrusca grapes have the most abundant natural sources of resveratrol. Resveratrol can be found in the vines, roots, stalks, and seeds of the plants, but the highest concentration is found in the skins.
The amount of resveratrol contained in the wine is related to the length of time the grape skins are present during the fermentation process. That's why the concentration of reseveratrol is much higher in red wine than in white wine where the juice is pressed from the grapes and the skins are removed early in the wine making process. Since grape juice is not a fermented beverage it is not a significant source of resveratrol. |

Resveratrol, The Fountain of Youth? Quite Possibly! |

It has long been somewhat of a mystery as to why the French could eat a high fat, high calorie diet and have a lower incidence of heart disease and live long healthy lives. It was known that wine had something to do with it but over the last couple of years, compliments of Dr Sinclair of the Harvard Medical Center and Rafael De Cabo Phd., they may have isolated the properties that answer the mystery.
The key is resveratrol in the fermented skins of the red wine grape, especially grapes that come from cooler climates.
There have been published papers on the fact that people (or animals for that matter) who have calorie restricted diets live longer.
Resveratrol does many things for the body including fooling the body into thinking it is calorie restricted. Hence, the French eating high calorie, high fat diets (with wine) may live longer with less incidence of heart disease.

Does Resveratrol in Red Wine Solve the French Paradox? |

Resveratrol is a polyphenol type flavonoid currently exciting great interest as a potential boon to health. Like other flavonoids and polyphenols, it is a very useful anti-oxidant in its own right, but resveratrol has attracted particular attention as a potential solution to the so-called "French Paradox".
This is the term used to describe the phenomenon, which has long been a puzzle to medical science, by which rates of cardiovascular disease in France have remained low relative to those in the rest of the developed world, despite the widespread national consumption of a diet high in animal fat and cholesterol, and a firmly entrenched tobacco habit. Of course France also enjoys many of the benefits of the so-called Mediterranean diet through its high intake of fresh fruit and vegetables, oily fish and olive oil, but there are good reasons to think that the consumption of red wine may be the real explanation of the apparent paradox.
It is known in any case that the moderate consumption of alcohol has a significant protective effect on the cardiovascular system, reducing disease by as much as 20-30%, but conventional medical opinion is characteristically cautious in acknowledging that the resveratrol in red wine may have any benefits over and above those which would in any case be provided by the alcohol. However, the role of fat-soluble anti-oxidants in protecting the circulatory system from damaging free radical attack is well understood, and it would therefore appear that the resveratrol and other polyphenols contained in red wine can only be beneficial. Laboratory tests, moreover, have shown resveratrol to have significant anti-coagulant and anti-inflammatory effects.

Resveratrol is a phytonutrient molecule whose time has come. It is a polyphenolic phytoalexin present in grape skins and red wine that has been shown to have antioxidant and anti-inflammatory properties. Resveratrol has potent antioxidant and anti-tumorigenic activities as well as important protective effects on the nervous system and more.
This component of red wine has been found to inhibit the proliferation of a variety of human cancer cell lines, including those from breast, prostate, stomach, colon, pancreatic, and thyroid cancers. More recently, reports on the potential for resveratrol to inhibit the development of cancer and extend lifespan in cell culture and animal models have continued to generate scientific interest.
Clinical trials are currently underway to address this question and to also determine whether resveratrol might be beneficial in cancer treatment. There is an extensive and growing amount of work devoted to the possible links between diet and a reduction in the risk of breast cancer as well as other forms of cancer. Recently, reports have come in that resveratrol could inhibit a number of cellular events associated with the initiation, promotion, and progression of cancer. |
