is dahi bara good or bad for the health

What makes you think that spices are not good for our health? In fact most Indian foods have a touch of spice. If spices were that bad, India would not have the kind of population that it has now. Any food can be good or bad depending on the constitution of the person having the food. I personally love dahi wada ( i suppose it is the same as dahi bara that you mention), dahi puri and all related stuff. They are yummy and even thinking about them makes my mouth water. Bye for now, I am going to have a dabi wada.
