I have ordered stevia leaves for my diabetic parents after knowing about its benefits for diabetes. But my mother disliked taste of stevia leaves when I used in her tea. So, can any one tell me about other sugar substitutes?  I have heard of coconut sugar, palm sugar, Jaggery powder as other better alternatives. So plz tell me about any other for my diabetic parents. I know stevia is one other most sought after sugar substitute. But they dislike its taste l. Currently we r using Jaggery powder in less amounts. So, plz doctors tell me about any other better alternative which we can use in less amount without too much affecting blood sugar level.
