It is pointless to talk about bread and rice which exist in all cuisines in the world. Certainly you are welcome to prefer Indian breads but don't say that they taste good because they have sugar/starch. All breads and rice have starch: you are making a sugar-related distinction where there's none. That leaves curries/sauces. Indian curries can have starch; they often don't. You can say a potato curry tastes good because it has potato, but you cannot generalize that to say curries taste good because they have sugar/starch. Also, my experience with Indian food comes from being Indian.
