Just in time for the festive season, champagne is suggested as a heart healthy drink. By increasing the availability of nitric oxide, champagne can improve blood flow and thus decrease blood pressure, the researchers claim. The substance that produces this effect is polyphenols, the same substance that has given wine a heart-healthy rumour. Regardless of the positive effects, the suggested two glasses of champagne a day might have a detrimental effect on the body that can overshadow any potential positive effect. Moderate to heavy alcohol consumption (over three drinks a week), increases the risk of breast cancer reoccurrence according to another study. Until larger studies can backup the claim that heavy drinking (14 glasses of champagnea week) is beneficial for our health, alcohol should not be consumed on regular basis or in large quantities.
