Diabetic patients can eat protein powder, but need to pay attention to the right amount, so as not to cause elevated blood sugar and increase the burden on the kidneys. Protein powder is rich in protein and can provide nutrition for diabetic patients. If diabetic patients have insufficient protein intake or suffer from hypoproteinemia, they can supplement protein through protein powder, and if their daily protein intake is sufficient, they do not need to eat protein powder. Excessive intake of protein powder will lead to calorie overload, which is not conducive to blood glucose control and increases the burden on the kidneys at the same time. Dietary regulation is an important part of the treatment process for diabetic patients, diabetic patients need to reasonably control the intake of calories, balanced with nutrients. It is recommended that diabetic patients take protein powder before taking in the regular hospital, consult the doctor after taking, so as not to lead to adverse consequences.
