Bok choy
What it is
Bok choy is a leafy Chinese cabbage. USDA lists the example used here as raw Chinese cabbage, pak-choi. That identity matters because other Chinese-cabbage records can describe a different vegetable.
What it does
The reference provides vitamin C, folate, calcium, and vitamin K. NIH lists bok choy among nondairy foods containing calcium and explains that calcium absorption differs among plant foods. The table reports calcium content, not the exact amount an individual will absorb.
Research context and ingredient forms
This is a raw-food profile. It should not be transferred directly to a stir-fry containing sauce and oil or used as proof that a serving corrects a calcium deficiency.
Using this information
Match pak-choi in the source description when comparing records. Weigh the edible portion and calculate other ingredients separately. A clearly named food is more useful than selecting a record simply because it contains the word cabbage.
