As the name implies, red wine vinegar is made from red wine, though the final product is nonalcoholic. The vinegar is acidic and is often used in salad dressing and marinade recipes. Beyond the trace amounts of certain nutrients, red wine vinegar offers a variety of other potential health benefits.
Red wine vinegar is very low in calories and doesn’t contain any fat. Using the vinegar on foods such as tossed green or pasta salads adds a burst of flavor without adding large amounts of fat and calories. Keeping your intake of fat, more specifically saturated and trans fats low is one step you can take to improve your overall health.
Because red wine vinegar is essentially sour red wine, it contains resveratrol, according to Cal Orey, author of “The Healing Powers of Vinegar.” Resveratrol might help reduce the risk of cancer and slow or inhibit the growth of cancerous tumors.
