Several studies have indicated that celery seed reduces blood sugar levels, an important part of managing diabetes.
A cup of celery contains about 29 micrograms of vitamin K. Recent research by University Medical Center Utrecht in the Netherlands concluded that those with the highest intake of vitamin K were nearly 20% less likely to develop type II diabetes compared with those who had the lowest intake of the vitamin (Diabetes Care. 2010 Aug;33(8):1699-705).
The celery anti-diabetic benefits can also might attributed to its unique ability to fight Helicobacter pylori (H. pylori), a bacterium that leads to a near three-fold increase in the risk of type II diabetes (Diabetes Care. 2012 Mar;35(3):520-5).
