Balsamic vinegar is an aromatic, aged type of vinegar, which is traditionally made from the concentrated juice or must of white grapes. It is very dark brown in color, and its flavor is rich, sweet and complex. Most aged balsamic vinegars are very expensive, although the commercial balsamic vinegar, which is sold in supermarkets, is typically made with concentrated grape juice mixed with a strong type of vinegar. Regardless of how it is produced, balsamic vinegar must be made from a grape product. Balsamic vinegar has a high acidity level, but the tart flavor is usually hidden by the sweetness of the other ingredients, making it very smooth and tasteful.
Balsamic vinegar contains a very low caloric content, and finding low-calorie foods is always the focus when trying to lose weight. Take, for instance, one tablespoon of balsamic vinaigrette salad dressing. It contains only 43 calories when compared to other creamy salad dressings that contain double of what balsamic vinegar contains. It has been suggested that when balsamic vinegar is consumed with carbohydrates, it keeps the blood sugar levels from rapidly increasing, thereby preventing sugar crashing later, which causes people to eat more.
Balsamic vinegars also contain resveratrol, which is a powerful antioxidant that is derived from various types of berries— especially grapes. It has been shown to have several positive cancer and weight-loss benefits. Studies have shown that the natural substance found in red wine and grapes offsets the bad effects of a high-caloric diet and helps to foster longevity. It is believed that resveratrol promotes weight loss by triggering the SiRT1 gene that is responsible for reducing fat stores in low-calorie diets. The research on resveratrol’s weight-loss benefits also indicates the possibility that its antioxidant properties may trigger certain receptors in the upper intestines, allowing for that prolonged feeling of being full.
