Wellness
A cup of cooked collard greens has about 63 calories, 773 mcg of vitamin K (644% DV) and 722 mcg of vitamin A (80% DV). (USDA) The NIH Office of Dietary Supplements says vitamin K is important for blood clotting and healthy bones, and that people who take the blood thinner warfarin (Coumadin) should get about the same amount of vitamin K each day. (NIH ODS) NIH ODS also says vitamin A is important for normal vision, the immune system, reproduction, and growth and development. Plants supply carotenoids such as beta-carotene, which the body can turn into vitamin A. (NIH ODS)
Pick, store and use
- Store
Wrap unwashed greens in moist paper towels and keep them in a sealed plastic bag in the crisper. They keep about 3–4 days. (MSU Extension)
- Use
Wash well in several changes of water; greens often carry dirt and grit. (MSU Extension)
- Freeze
Pick young, tender leaves, cut off woody stems, blanch collards 3 minutes, then cool and pack. (MSU Extension)
