What is "Saboo Dana"? Can it be taken by diabitics?

Saboodana is prepared from Tapioca and is high in starch content. In large quantities it is not good for diabetes. Small quantity, if consumed once in a while, is harmless. All starches get converted into sugar and hence is not good for diabetics. Whether it is rice or wheat, small quantities only are allowed. Say 100 grams pert day.
