in my opinion more restrictions on diets on the diabetics patients  are not accepted by them, because it is a life long treatment and patients are most disobedience  to the doctors advises. if you restrict the sugar so he will try to take, if you give little liberty to the patient and his attendant,being a consultant i am facing every day. so advise him to take in moderate and to maintain health balanced diets are essential for him.more restrictions most disobedience,
