As a diabetic who has been eating for half a year, I think it is very useful. Drinking a cup half an hour before a meal has a strong feeling of fullness, which can reduce the calorie intake at dinner on the basis of paying attention to diet and help control sugar. Blood sugar has been well controlled by half a year. Doctors have always suggested eating more dietary fiber. Because I'm worried about not getting enough dietary fiber every day, I start eating light and healthy food, which is really good for my health.
