Wellness
A cup of shredded green leaf lettuce has about 5 calories, 45 mcg of vitamin K (38% DV) and 133 mcg of vitamin A (15% DV). That makes it a good source of vitamin A. (USDA) The NIH Office of Dietary Supplements says vitamin K is important for blood clotting and healthy bones. (NIH ODS) In large long-term studies cited by Harvard's Nutrition Source, green leafy vegetables such as lettuce, spinach and Swiss chard were among those most strongly linked with lower risk of cardiovascular disease.

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
Greens often carry dirt and grit, so wash them well in several changes of water just before using. (MSU Extension)
