Collard greens
What it is
Collard greens are a leafy vegetable, listed as collards in the USDA reference. The table here is for raw greens, not a cooked dish with broth, meat, or added fat.
What it does
The reference provides 4 g of fiber, 129 micrograms of folate, and 437 micrograms of vitamin K per 100 g. Folate supports DNA production and normal cell division. Calcium and vitamin C are also recorded in the food profile.
Research context and ingredient forms
The nutrient amounts describe 100 g of raw edible greens. They do not describe a cup of cooked collards or account for ingredients added during cooking.
Using this information
When estimating a cooked dish, choose a cooked record that matches drainage and salt where possible, or use the recipe. Measure the portion on the same basis as the chosen record.
Considerations
If you use warfarin, consistency in vitamin K intake matters. Discuss substantial changes in leafy-green intake with your prescriber; the goal is not automatic avoidance.
