Guar biscuits in the diabetic diet.

A new type of guar-containing biscuit has been developed and incorporated into the diabetic diet in both short- and medium-term studies. It has been found to be effective in reducing the postprandial rise in the blood glucose level and in improving glycaemic control, as shown by reduced fasting blood glucose values and decreased 24-hour urinary glucose excretion. This form of guar has proved to be palatable and acceptable to patients. It was effective in smaller quantities than have previously been tested and may prove a valuable adjunct in the treatment of diabetes.
