Diabetic patients are advised to eat less or no root vegetables. For diabetic patients, dietary management is crucial, and its main purpose is to control blood glucose by rationally controlling the total calorie and nutrient distribution of the diet. There are no contraindications in a normal diabetic patient’s diet, but the amount of food eaten needs to be controlled. Generally speaking, lotus root powder is made from lotus root, which is rich in iron, calcium and other trace elements, plant protein, vitamins and other nutrients, which can provide diabetic patients with nutrition. However, lotus root powder itself also contains a lot of starch, consuming too much will affect the control of blood glucose, so it is recommended that diabetic patients eat less or not eat lotus root powder. In addition to paying attention to diet, diabetic patients should monitor their blood glucose and undergo regular checkups in the hospital.
