The purple grapes used to make red wine and purple grape juice contain types of phytochemicals called polyphenolic compounds. These compounds support normal, healthy heart functioning. The polyphenolic compound found in the skin and seeds of grapes (used in making purple grape juice and red wine) has a special anticlotting function, which reduces plaque buildup in the arteries. This substance also helps to keep LDL ("bad") cholesterol from attaching to the arteries. Therefore, including purple grape juice in your fruit consumption a few times a week, has an added health bonus.
These compounds are also found in many other fruits, including cranberries, blueberries, and raspberries. Despite the benefits of red wine, it is not recommended that you begin drinking wine or other alcoholic beverages if you do not already do so. If you consume wine, it is recommended that you do so in moderation.
