Well if you want to decide whether to get the bubble tea with boba balls or the lychee jelly in terms of health benefits, you should go with lychee jelly.  The tapioca pearls are of course high in calories as they are nothing but starch. But in addition to starch, there are more chemicals used to stabilize and improve the texture of the boba balls. So, bobs balls have high carbs and chemicals. Now the lychee jelly has equal if not less chemical ingredients, but it is much lower in carbs.
