French scientists say grape juice seems to also work to prevent cardiovascular disease like red wine. Researchers at the University of Louis Pasteur de Strasbourg are studying the effect of Concord grape juice on the heart.
Dr. Valerie Schini-Kerth, who led the study published in this cardiovascular research journal, said: 'Grape juice may work (against heart disease) similar to red wine but not. there is alcohol - this is a very important message '. Red wine and some grape juice have high polyphenol content and this is the substance that prevents the production of a cardiovascular-related protein, which is the leading killer in Western countries.

Cardiovascular problems arise when endothelial cells responsible for constituting blood vessels do not function normally.
Dr. Schini-Kerth and her team found that polyphenol in Concord grape juice activates nitric oxide-producing endothelial cells, a substance that helps fight cardiovascular disease, maintains vascularity. Healthy blood and blood pressure stability.
Polyphenols in red wine or Polyphenol in grape juice are equally effective. Dr. Schini-Kerth said: 'However, not all grape juice has a positive effect. For a positive effect, the juice must have high polyphenol content. '
The amount of poyphenol in grape juice as well as in red wine will depend on the type of grape used for pressing and how to make it.
Mrs. Schini-Kerth: 'We currently have information on more than 100 different wines and polyphenol content in these wines. What we know is that the most protective wines are the ones with the highest polyphenol content and this has been verified. ' However, according to Dr. Schini-Kerth, there is almost no information about grape polyphenol content.
Scientists are now studying pig cells, a typical model for studying human cells.
They are currently studying the effect of grape juice on healthy blood vessels, and are planning to conduct a further study to see if grape juice has the same effect on marked blood vessels. Is the cardiovascular disease effective?
