Why Black Tuscan Kale (Cavolo Nero) is Good for You
Black Tuscan kale, or cavolo nero, is a green leafy vegetable that is starting to gain popularity outside of Tuscany, Italy, where it has been used for years as a tasty and healthy ingredient in salads, gratins and soups. Also known as lacinato kale, dinosaur kale, or nero de toscana, this dark green leafy vegetable provides many of the same health benefits as the common curly kale and the red Russian kale, but it also provides some unique benefits. Here's a lowdown of the purported nutritional and health benefits of cavolo nero:
Health Benefits of Cavolo Nero
Like all Brassica vegetables, black Tuscan kale or cavolo nero contains glucosinolates such as glucoraphanin. The glucoraphanin and the other glucosinolates in black kale are well-known precursors to isothiocyanates, much-researched health-benefiting compounds. Numerous studies suggest that foods rich in isothiocyanates may help prevent cancer and even suppress the growth of tumors. Isothiocyanates' anti-cancer effects have been attributed to their ability to eliminate potential carcinogens from the body, reduce DNA damage, and facilitate the apoptosis (self-destruction) of cancerous cells.
Most of the studies related to the anti-carcinogenic properties of isothiocyanates have focused on colon cancer and breast cancer, but there's also evidence that diets rich in glucosinolates may also help reduce the risk of ovarian cancer, prostate cancer, and bladder cancer.
Aside from being a good anti-cancer food, Tuscan kale has some interesting properties that could prove to be beneficial to MS patients. An Italian study published in the journal CNS Neuroscience & Therapeutics in August 2013 found that cavolo nero had neuroprotective and immunomodulatory effects in experimental autoimmune encephalomyelitis, an animal model for multiple sclerosis (MS). However, further research is needed before any definitive conclusions about the health benefits of black kale for MS patients can be made.
If you're still not impressed by the nutritional value of cavolo nero, consider this: this brassica vegetable is among the most antioxidant-rich foods on Earth. The antioxidants in Tuscan black kale destroy free radicals, unstable molecules that can cause damage to your body at the cellular level. The damage caused by free radicals has been implicated in the pathogenesis of a wide range of diseases and health problems, including asthma, macular degeneration, diabetes, heart disease, thrombosis, atherosclerosis, pre-mature aging of the skin, Alzheimer's disease, and rheumatoid arthritis.
Finally, all common kale cultivars provide plenty of carotenoids, particularly lutein and beta-carotene. Carotenoids have various roles in human health, but their best-known health benefits relate to their eye health protecting qualities. A large body of evidence suggests that carotenoids may help fight age-related macular degeneration, impaired night vision, cataracts, and retinitis pigmentosa.
