From a dietetic standpoint Savoy cabbage is low in calories (before they are seasoned), and rich in fiber, folic acid, vitamin C, vitamin B, and even richer in vitamin E, which makes them a good preventive against spontaneous abortions; they’re also quite rich in calcium, and therefore indicated for those suffering from osteoporosis. They also contain antioxidants, and sulfur compounds that inhibit the growth of Helicobacter Pilori, one of the primary causes of stomach ulcers. In short, they’re good for you, unless you’re prone to kidney stones.
