Resveratrol is a phytoalexin. This group of polyphenols are the antibiotic compounds that plants produce as part of their defense system to combat disease. Plants insulin plant powder eucalyptus, spruce, and lily, and the mulberry fruit tree and the legume peanuts contain resveratrol, but the Vitis vinifera, labrusca, and muscadine grape that are the most abundant sources of Resveratrol, and these grapes are used to make wine. The concentration of Resveratrol in the wine appears to be linked to the length of time the skins are left to process.
Poor nutrition, stress, air pollution, smoking, ultraviolet light or disease can all contribute to upset our oxidative balance. The oxygen we breathe, we get from air, and we need oxygen for normal metabolic activity. This is called ‘ground-state’ or ‘triplet’ oxygen, and it is stable in this form. Harmful reactive oxygen species such as singlet oxygen, superoxide, peroxyl and hydroxyl radicals are formed as a result of photo-oxidation, physiological stress and normal immune system functions. Singlet oxygen is an excited form of ground state oxygen that is formed from normal biological functions; it is highly reactive and long-lived and must transfer this excess energy to another molecule to relax again to the ground state of oxygen. Resveratrol is an antioxidant that can supply an electron to reduce the free radical damage, and it does this and is able to remain stable. Cancerous cells invade normal tissue. They are aided by enzymes called matrix metalloproteinases. In studies, resveratrol has been found to inhibit the activity of at least one type of matrix metalloproteinase. Invasive tumors grow rapidly, and they need to develop new blood vessels to fuel this growth. This process is called angiogenesis, and in vitro studies have shown that resveratrol will inhibit this process.
Other well known antioxidants such as Vitamin C and E are not as protective as resveratrol.
Resveratrol helps prevent insulin resistance, Insulin resistance is a precursor to diabetes, a condition in which the body becomes less sensitive to insulin. Insulin is a hormone that lowers blood sugar. Resveratrol has also been linked to prevention of age-related problems such as heart disease and insulin resistance. Researchers believe that resveratrol activates the SIRT1 gene, a biological mechanism that seems to protect the body against the harmful effects of obesity and the diseases of aging.
Resveratrol is thought to limit the spread of cancer cells and trigger the process of cancer cell death (apoptosis).
Resveratrol prevents the oxidation of LDL “bad” cholesterol, helps reduce inflammation, and makes it more difficult for platelets to stick together and form the clots that can lead to a heart attack.
Resveratrol may protect nerve cells from damage and the buildup of plaque that can lead to Alzheimer’s
