During a crisis, your body releases turbocharged stress hormones that flood into your cardiovascular system to prepare you to deal with the emergency at hand. Unfortunately, stress hormones flooding the system can also cause damage. Antioxidants—which are beneficial natural chemicals found in high levels in certain foods—act as scavengers of free radicals, the by-products that are created when cells use oxygen. Antioxidants can both prevent and repair damage caused by free radicals. Squeeze or use a juicer to extract the juice from organic fruits and vegetables such as oranges, limes, strawberries, apricots, peaches, cantaloupes, carrots, and green leafy vegetables. Pomegranate, purple grapes, and cranberries are high in phytochemicals and antioxidants as well. Drinking fresh, organic juice is especially beneficial when you are under duress.
