I have one more question. Is white rice actually made of white, refined flour?

No, white rice consists of grains from the rice plant. The "milling" process removes its husk, bran, and 'germ', but a kernal of rice remains. It is not turned into flour.

White rice is nutritionally not much different from white flour. Both are starch, devoid of vitamins and minerals found in the bran and germ. I would classify it in the nutritional same category as white, refined flour.

No, white rice is not made from white, refined flour. White rice is actually made from the grains of a type of grass called Oryza sativa. The grains go through a milling process to remove the outer husk, bran, and germ layers, resulting in white rice. The milling process removes these layers, which contain most of the essential nutrients, fiber, and natural oils present in the whole grain, leaving behind the starchy endosperm.

To confirm this information, you can conduct a simple search using a reliable search engine or visit trusted culinary or educational websites that provide information on the topic. Some examples of trusted sources include agricultural and governmental websites, reputable health organizations, educational institutions, or culinary resources. Reading articles or references from multiple reliable sources is often a good practice to ensure accuracy and obtain a well-rounded understanding of any subject.
