I should warn regarding this. Rice is my staple food. And I come from ethnic background where rice is cultivated vastly and it is the staple diet from morning to evening.
You should not eat raw rice. It will cause Anemia. This what my mother and grand parents will say when we try to eat raw rice in the childhood. We will boil rice until it is cooked and mix it with sambar, rasam, saarus, curd or curries and eat it. The boiled rice is called Anna, Annam, Soru, Saadham in different South Indian Languages.
I will tell another fact: In our farms we don't give raw rice particularly parboiled rice to goat or sheep. If you feed your goat with at least 1 pound of parboiled raw rice and give water to drink. The goat will die the next day, The died goat will have bloated stomach.
Try anything, but with some reference.
