Even though all the elements present in wine play an integral roll in the beneficial factors of wine, but the single most beneficial agent present in red wine that contributes more to health in your body than perhaps any other substance is polyphenol.
Micronutrients of wine are principally composed of minerals (calcium, magnesium, potassium) and polyphenolic substances.
Present in great amount in red wine, 2 to 4g per liter on average, polyphenols are a big family of natural substances or micronutrients that are in the roots, stems, leaves and flowers of all vegetable plants.
For example red wine or green tea have a large amount of polyphenols.
They are secreted by the plant and allow it to fight the attack of toxic microorganisms such as microscopic fungi.
This antioxidant is mainly present in the skin of the grape and more present in some grapes than others, like Pinot Noir.
Resveratrol and Tannins that are famous for their therapeutic properties are part of the polyphenol family.
Resrveratrol is of course claimed and proven in major laboratories to be effective in heart disease and cancer prevention and weight loss.
It is also known to help lower blood sugar and boost the immune system and most importantly extend the life span.
Tannins also have their therapeutic attributes.
Existing in the skin and seeds of grapes, tannins confer to wines astringent properties, and they have been used for a long time for their anti diarrheic effect.
Tannins are also phenolic molecules with anti wrinkle effects on the body.
These are the principle reasons why wine is such a favorite with the medical community.
These health benefits contribute to a more healthy and balanced body, all thanks to this wondrous substance made available by the divine creation called polyphenol.
