Grape juice is the best resistance to oxidation

Grape juice is the best resistance to oxidation

According to a new study that purple grape juice is a privilege source most of its content of antioxidants between the different types of juice are also common.
Researchers from the University of Glasgow Scottish purple grape juice that offers the highest ability to resist oxidation, and has a higher quantity and wider range of phenol antioxidant is common among the 13 species of fruit juices and drinks, which have been tested and evaluated.
The researchers used two methods to diagnose and measure every single compound of phenolic compounds in fruit juices and drinks, and drinking fluids are high performance (hplc) and mass spectrometry (ms).
They also used an additional analysis to measure the phenolic content of juices and the roots of oxygen absorption capacity (orac) to measure the ability of antioxidants. Varied significantly according to the flavor of the ability to resist oxidation and the level of diversity of phenol antioxidant.
Antioxidants:The present study is the second in less than a year that appears beyond the capacity of antioxidants to grape juice.
In July last classified study published in the "American Journal of Clinical Nutrition" this juice as a drink first in terms of antioxidant capacity (per amount) of more than 1,000 food and drink in the United States.
It is known that antioxidants are active biological compounds present in food, and play an active role in the life of the human body, explains Professor Alan Koziyr professor of plant bio-chemistry and human nutrition at the University of Glasgow.
And the reduced oxygen to the roots of the free, antioxidants help to maintain the balance of oxidation, and may be actually responsible for improving the health status and conservation. And phenol compounds (phenols) is an effective set of natural antioxidants, and is believed to play a role in the prevention of chronic diseases.
Best benefits:Professor Koziyr striking that, while growing awareness of the importance of antioxidants and polyphenols, this study highlights the importance of attention to every single type of compounds that we consume, because the health benefits of each type is different.
According to the University of Glasgow research team that the best health benefits of polyphenols can be achieved with consumption of a range of fruit juices including purple grape juice, in addition to the juice, "grapefruit" juice, cranberry juice, apple dark color.
This is because the purple grape juice is a rich source Btnoaah wide range of polyphenols, especially Filavanolat Alonthusianinat and strong, and the juices "grapefruit" and cranberries and apples are rich in the dark with some other polyphenols.
