Is sago or tapioca pearl good for pregnant women to make khichdi, kheer or bubble tea? Sago and tapioca pearls, though often used interchangeably and having similar shape and form, may come from different sources. Sago is made from the pith of an array of tropical palm trees, whereas Tapioca pearls are made with tapioca or the starch from cassava, a root crop. Another variation of sago, known as nylon sago is also available in certain countries such as India, which refers to partially pre-cooked sago which is steamed and dried before packing. All three of these ingredients are often used interchangeably in sweet as well as savory dishes and bubble teas. Sago, nylong sago and tapioca pearls are safe to eat during pregnancy.
