For me, rice is the best one - because it is the main food that we have every day. Corn and wheat may be the other alternative. These three provide sufficient carbohydrate and vitamin B1 for our body. If you ever visited Indonesia, you will understand why I say like this. Moreover, the rice from my province is the best one in Indonesia (maybe also in the world). And it is also the reason why the people from my province is well known with their ability at cooking and organizing restaurant. Indonesian people call the restaurants as Padang Restaurant, and the most famous menu for the rice is "rendang". If you want to taste delicious meal in rice, just come to my province - Sumatera Barat in Indonesia. Padang, the capital of Sumatera Barat is only one hour flight from Singapore.
