Generally, porridge is high in sugar. The common ingredients of congee are rice, millet, etc. These ingredients are mainly composed of starch, which has a very high content of carbon-hydride compounds. For diabetic patients with unstable blood sugar control, drinking congee can easily increase blood sugar, which is not conducive to the control of the condition. Therefore, it is generally not recommended for diabetic patients to eat congee. In daily life, patients with high blood glucose are recommended to eat more fresh vegetables and fruits, pay attention to the intake of nutrients, maintain a comprehensive and balanced nutrition, and choose a low-salt, low-fat, low-sugar diet, along with regular aerobic exercise, which will help stabilize blood glucose control. It is recommended that diabetic patients monitor their blood glucose regularly and go to regular hospitals if they feel unwell.
