Raw celery is a 0, which is the perfect number for diabetics, on the GI scale. Because celery will not break down quickly into sugar in the bloodstream, it is an excellent vegetable choice for diabetics. One serving of celery contains only 1.2 grams of digestible carbohydrates, and half of those carbohydrates are from dietary fiber. The dietary fiber helps to curb the appetite and to curb any cravings for sugary foods. Furthermore, celery contains very little natural sugar, and all of that sugar is burned off during digestion so that it does not enter the bloodstream. Like carrots, celery has nutrients that have been shown to reduce the risk of Type 2 diabetes. Its high vitamin K content along with its ability to block the H. Pylori bacteria from growing in the digestive tract contribute to this factor. For these reasons, celery has positive effects on blood sugar and is a diabetic person’s best friend.
