In addition to containing a rich concentration of vitamins, minerals, and health-promoting sulfur compounds, Brussels sprouts also provide the powerful phytonutrient antioxidants, lutein and zeaxanthin. Members of the carotenoid family, these two phytonutrients help defend your cells from the damaging effects of free radicals and have been shown to protect your eyes from developing age-related macular degeneration and cataracts.
All about Brussels Sprouts (This bloke sure does his homework)
While the origins of Brussels sprouts are unknown, the first mention of them can be traced to the late 16th century. They are thought to be native to Belgium, specifically to a region near its capital, Brussels, after which they are named. They remained a local crop in this area until their use spread across Europe during World War I. Brussels sprouts are now cultivated throughout Europe and the United States. In the U.S., almost all Brussels sprouts are grown in California.
