Diabetic patients are advised not to eat lotus root powder because it contains relatively high calories and is consumed by steeping it in boiling water to form a paste-like substance, an intake method that can easily lead to a relatively rapid rise in blood sugar after consumption. If patients eat lotus root powder, they should reduce the intake of other forms of staple foods accordingly, so as to ensure that the calorie intake is roughly within the control range, which is good for blood sugar control. Nevertheless, the preferred diet for diabetics is not lotus root powder, but rather steamed buns or dry rice, which have relatively little effect on blood sugar.
