Fresh green beans are very low in calories and contain no saturated fat. Plus they are a good source of vitamins and minerals.
Green beans contain vitamin A, and contain antioxidants such as lutein, zea-xanthin and ß-carotene in good amounts. These help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species.
Free Radicals are highly reactive molecules that can damage muscle proteins and are one of the causes of post-exercise muscle soreness. Free radical buildup is a natural consequence of exercise. The more oxygen we breathe, the more free radicals we produce. Free radicals cause fatigue by interfering with muscle contraction, interfering with the delivery of oxygen and nutrients to the muscle and the release of brain fatigue signals.
