Bottle Gourd or Doodhi or Lauki is one of the highly underrated vegetables I guess. I really believe that all the haters of lauki that I know were not served the tastier versions of this very nutritious vegetable. Even in my home, I have seen only 2-3 versions including a sweet! You might have noticed that in hospitals they serve lauki generously; that is because it is high in water content (92%) and it helps lower bad cholesterol. It is a rich source of Vitamin C, Kand Calcium. It is also beneficial for diabetic patients.
